  1. I believe there are electric vehicle operating in mines in Australia right now. Battery-electric mining vehicles are operating in Australian mines today, but battery-electric haul trucks are mostly still in the trial or early deployment stage. Already operating today Fortescue is operating: 16 electric excavators in the Pilbara Electric drill rigs Various smaller electric mining equipment being tested and introduced into service Fortescue says each electric excavator saves about one million litres of diesel per year. Battery-electric locomotives are also now being commissioned on Fortescue's Pilbara railway. These are not prototypes sitting in a workshop—they are being prepared for operational use on the rail network. Giant haul trucks (the really big ones) This is where things get interesting. BHP, Rio Tinto and Caterpillar are currently trialling two battery-electric Cat 793 haul trucks at the Jimblebar iron ore mine in the Pilbara. These are 240-tonne-class trucks operating in real mine conditions, but they are still part of a formal trial rather than routine fleet deployment. Fortescue has fitted out its first battery-electric Liebherr T264 haul truck and has commissioned a 6 MW fast charger capable of charging a truck in about 30 minutes. However, Fortescue has stated that its first operational battery-electric haul truck is expected to enter service later in 2026. So the answer is: Equipment Operating in Australian mines now? Electric excavators Yes Electric drill rigs Yes Battery-electric locomotives Yes (commissioning/early operation) Small electric mine vehicles Yes 240-tonne battery haul trucks Trialling now Large battery haul truck fleets Not yet The biggest surprise for many people is that excavators may electrify before haul trucks. An excavator works in a relatively fixed location and can be supplied power more easily, whereas a haul truck may need to climb several hundred metres carrying 200–300 tonnes of ore, making battery size, charging speed and mine-site power infrastructure much more challenging. If you're wondering whether these trucks actually make economic sense, the answer appears to be increasingly "yes" for remote mines. A large haul truck can consume several million litres of diesel over its life, so even expensive batteries can be worthwhile if charging infrastructure and renewable power are available. That's one reason companies like Fortescue are pushing so hard—they believe electrification will eventually reduce operating costs as well as emissions.
  2. Don't be ridiculous, it obviously means keyboard players 😁
  3. Yes that is true. The comment I was addressing was this: So lets see what is going on with mining vehicles and machinery. For many mines, getting renewable electricity for crushers, conveyors, processing plants, camps and offices is relatively straightforward. The really difficult challenge is replacing the huge diesel haul trucks, loaders, trains and other heavy equipment. Where the industry is today Processing plants Many Australian mines are already running a large portion of their fixed equipment on renewable electricity because the power comes from the site's solar, wind and battery systems. This includes: Crushers Conveyors Mills Pumps Processing plants Workshops and accommodation facilities These are the easiest loads to electrify. Haul trucks The giant haul trucks are the biggest diesel users. A single large haul truck can burn millions of litres of diesel per year. The major miners are now trialling battery-electric trucks: BHP and Rio Tinto are jointly trialling 240–250 tonne battery-electric Caterpillar haul trucks at Jimblebar in the Pilbara. Fortescue has developed its own high-power charging systems and expects its first operational 240-tonne battery-electric haul truck to enter service in 2026. Fortescue is probably the most aggressive 5 Fortescue's strategy is not just to build renewable power stations but to electrify the fleet as well. The company is: Building more than 1.4 GW of solar generation in the Pilbara. Installing large battery systems. Deploying battery-electric haul trucks. Operating electric excavators. Testing electric dozers, graders and loaders. Their goal is to eliminate fossil fuels from their terrestrial iron ore operations by 2030. Mining railways are also beginning to electrify. BHP has taken delivery of Australia's first purpose-built battery-electric heavy-haul locomotives for testing on its Pilbara rail network. These locomotives use large battery packs and regenerative braking. How much diesel is still being used? For most Australian mines today: Equipment Renewable/Electric Status Processing plants Often 50–100% renewable electricity Site buildings Often 50–100% renewable electricity Conveyors and crushers Often renewable-powered Light vehicles Increasingly electric Excavators Early electric deployment Haul trucks Mostly diesel, some electric trials Trains Early battery-electric trials Drill rigs Limited electric deployment So when you hear that a mine is "80% renewable", that usually means 80% of its electricity, not necessarily 80% of all its energy use. Diesel trucks can still account for a very large share of total energy consumption. This is one reason critics sometimes argue that mining companies overstate their progress, while the companies respond that the technology for replacing 250-tonne haul trucks is only now becoming commercially viable. The next five years will probably determine whether battery-electric mining fleets become mainstream in Australia.
  4. Australia has quite a few mines that either run partly on renewable energy or are among the world's leaders in renewable-powered mining. Very few large mines operate on 100% renewables all the time, but several are regularly achieving 50–90% renewable penetration and occasionally reaching 100% for extended periods. Major Australian mines using renewable energy Mine Commodity Location Renewable Energy System Renewable Share Agnew Gold Mine Gold WA Wind, solar, battery, gas microgrid Typically 50–60%, up to 85–95% at times (Australian Renewable Energy Agency) Bellevue Gold Mine Gold WA Solar, wind and battery hybrid system Designed for ~80–90%; achieved 155 consecutive hours on 100% renewables (Reddit) Kathleen Valley Mine Lithium WA Solar, wind, battery, gas hybrid Around 60–80% renewable energy (The Australian) Mt Weld Mine Rare earths WA Renewable hybrid power system Reportedly exceeded 95% renewable share during one quarter (Reddit) St Ives Gold Mine Gold WA Large solar and wind project under development Expected to provide over 70% of site power (Reddit) DeGrussa Mine Copper/Gold WA Solar farm with battery storage One of Australia's pioneering renewable-powered mines (Australian Renewable Energy Agency) Weipa Mine Bauxite QLD Large solar installation Partial renewable supply (Australian Renewable Energy Agency) Tropicana Gold Mine Gold WA 24 MW solar, 24 MW wind, battery system Significant renewable contribution to mine power (Solar Now) The leaders Agnew Gold Mine Often regarded as the pioneer. It was the first Australian mine to use large-scale wind generation as part of a mine microgrid. The site combines: 18 MW wind farm 4 MW solar farm Battery storage Gas backup It typically obtains 50–60% of its energy from renewables and can reach much higher levels under favourable conditions. (Australian Renewable Energy Agency) Bellevue Gold Mine Currently one of the most ambitious renewable mining projects in Australia. The mine recently reported operating for 155 consecutive hours (over six days) entirely on renewable energy with diesel and gas generators switched off. (Reddit) Kathleen Valley Lithium Mine A good example of a new-generation mine being designed around renewables from the outset rather than adding them later. It uses a large solar-wind-battery system and has reportedly achieved renewable shares above 80% in some periods. (The Australian) An interesting pattern Most of Australia's renewable-powered mines are in remote Western Australia. That's because: Diesel fuel is expensive to transport. Many mines are off-grid. WA has excellent solar resources. Wind and solar can often generate electricity more cheaply than diesel generation. As a result, renewable energy is often adopted primarily for cost savings and reliability rather than environmental reasons alone. The economics can be very attractive for remote mining operations. (Australian Renewable Energy Agency) If you're interested, I can also list the major iron ore mines (BHP, Rio Tinto, Fortescue) and explain how far they have progressed toward running on renewable energy, because the Pilbara iron ore sector is currently undergoing a huge transition.
  5. A lot of industries are already exploring renewables and some are already off grid such as parts of the mining industry. As solar and batteries get cheaper, it will be irrational for households to connect to the grid merely to support the grid for the benefit of industry.
  6. I think this is a humorous reference to the shape of the roof.
  7. I agree, but the thing is that to some people not automatically believing he is innocent equates to "not supporting the troops" My point is that BRS is not the only soldier in this story. Those who beleive BRS is innocent surely must believe that the 20 soldiers who brought this to light must be lying. It will be tested in court.
  8. I beleive you can avoid any tax,if you sell it within 2 years and under some circumstances this period may be able to be extended.
  9. Just to be clear this is not a new rule. The method of valuation has changed. I am not necessarily disagreeing with your points, though.
  10. The only CGT I have first-hand experience of was on the sale of my house on 44 acres. As has been discussed on this forum in the past, there is a rule that you are liable for CGT on everything over 5 acres (2 Hectares). Unlike CGT on collectables, you are legally allowed to do the valuation yourself (but you may need to show your workings out). The exempt 5 acres need not be one parcel of land, so you choose all the most valuable bits to exempt. In my case, the house and infrastructure (water tanks, septic tanks, etc. and a strip of river frontage. I then was able to deduct the cost of ownership (rates etc maitanance of fences and other things). I was able to aggressively (but legally - I think) whittle the CGT bill down to $1500. I did half expect a please explain letter; however, it never came, and 9 years later, it is too late for them, unless they detect out-and-out fraud. I did plenty of research, and I actually found in an obscure place a tax department internal document that listed the conditions that trigger an audit with regard to land sales, so I felt on safe ground. The thing is, compared to some people selling land, my case was pretty trivial. It does not really make sense for ATO to spend vast sums of money detecting the sale 1 watch or piece of jewellery in a private sale. This is not tax advice!
  11. In practice, for the ordinary person, I suspect it will be difficult to enforce. A CGT already exists; it is just the method of calculation and valuation that has changed (as far as I can see). If Onetrack sells me some of his lovely junk, how would the ATO even know? Since I have been downsizing, I have sold many possessions, mostly they have lost value, but some musical instruments have gained in value and are probably subject to CGT. Pretty hard to detect, though.
  12. OK I think I have my answer. https://share.google/aimode/gHgADhB5bpfnRHy3G I think if you don't have a valuation, you can use what is called an "apportionment formula", but in some circumstances, this may be less advantageous.
  13. PM, are you saying that the change is regarding the need for a valuation? CGT on items like jewellery has existed for a long time, but are there specific changes regarding the method of determining its value?
  14. Approximately 209 million people were registered to vote in the 2020 presidential election and 158,427,986 ballots were submitted for president (75.8% of registered voters).
  15. To clarify, the word average was quoted in the thread title "Sympathy for the AVERAGE American." This is why I included the word average, not as a mathematical statement. Some have suggested that Americans (average or otherwise) are not worried about Trump, so my point is that come the midterms, we will know what they do think or at least what those who vote think.
  16. I guess we might get a feel for how the average American (voter) feels in November.
  17. And how is that looking so far? As I understand it, the memorandum of understanding which lasts for 60 days, does not include handing over nuclear materials. It does seemingly involve unfreezing billions dollars of assets for the Iranians. I also understand that the Iranians have not ruled out charging tolls for ships using the Strait of Hormuz. Then there is regime change. This has not occurred, but several leaders have been killed, and it is believed their replacements are even harder line. The US has squandered its arsenal of weapons such as the Tomahawk Missile, which will take years to replenish. https://militarywatchmagazine.com/article/us-indefinitely-suspends-tomahawk-japan#:~:text=The United States has indefinitely,day U.S. assault on Iran. "The United States has indefinitely suspended the delivery of Japan’s first 400 RGM-109 Tomahawk cruise missiles, due to serious shortages of the missiles in the U.S. Navy that have resulted from the 39 day U.S. assault on Iran. " It would be a great time for China to take Taiwan. But I guess if Americans are feeling down because of increasing healthcare costs, high petrol prices, etc. I am sure they are massively cheered up by the bulldozing of the East Wing to build that big, Beautiful Ballroom to be used by the ultra-rich. MMmmmm you've got to love all that gold leaf. I bet they they cant wait for the Arch De Trump or to get their first $250 bill with the dear leader's face on. I am sure they are so proud of the immense intelligence of the leader. So smart that he aces tests that are used to detect dementia. But of course, the doctor administering the test has never seen such a perfect score.
  18. One Nation, led by Senator Pauline Hanson, has faced numerous financial and lobbying controversies over the years, including undisclosed campaign funds, police raids, and National Anti-Corruption Commission (NACC) referrals. [1, 2, 3] Key Corruption and Financial Controversies: NACC Staffer Referral: In May 2025, a former One Nation senator referred a senior party staffer to the National Anti-Corruption Commission amid allegations the staffer sought commissions from clients met during a 2017 Senate inquiry. [1] National Treasury Audits: In mid-2026, financial accounting reviews revealed the Queensland branch of One Nation accumulated missing assets and repeatedly failed to lodge required audited financial statements with the regulator since 2022. [1, 2] Defrauding the Electoral Commission: In late 2021, the party’s national treasurer, Alexander Jones, was charged with fraud following a referral from the Electoral Commission of Queensland (ECQ) over fraudulent documentation relating to election funding. Jones later pleaded guilty to attempted fraud in 2022. [1, 2, 3] Internal "Money Grab" Allegations: In August 2023, two of One Nation's New South Wales MPs quit the party after alleging under parliamentary privilege that officials improperly misappropriated and funneled state funds into federal coffers. [1] Undisclosed Plane Donations: The party was referred to the Australian Electoral Commission (AEC) following allegations that party officials hid the true ownership and donations of a light aircraft, and misused state taxpayer money. [1, 2] NRA Lobbying Scandal: An undercover investigation in 2019 captured senior party advisers seeking millions of dollars in campaign donations from the US National Rifle Association (NRA) in exchange for lobbying to weaken Australia's gun laws. [1, 2, 3]
  19. Until the last few days, this forum has been pretty respectful between people with different political views. Suddenly, it has deteriorated. I am happy to listen to any reasoned, respectful argument.
  20. One problem is that during an election, the electorate doesn't really want to hear the truth. Take house affordability. Most people acknowledge that homes, especially for first-time buyers, are way too expensive. A politician who promises to lower housing prices will surely do well until people who actually own a home realise that devaluing housing prices devalues their property as well. Not a great election pitch to existing home owners. Note, I personally am fine with that; you can't have everything. I find that voters at election time are rather like kiddies sitting on Santa's lap. They just want to be told what is in it for them.
  21. I can relate to this. I mostly have 1 bottle a week, but these days Mrs Octave doesn't drink much at all so I end up drinking most of it. Whilst I am pretty moderate (mostly) if there is an open bottle, I will finish it. We are just experimenting with going out to a wine bar and having just one nice glass rather than a whole moderately priced bottle. Four times a year Mrs Octave is away for a week, so I tend to overdo it. When visiting my son in NZ I do fall into a bit of a trap. His household is pretty nerdy. They brew beer which is stored under the house and is piped into the kitchen. There are 3 taps with 3 different delicious home brews. A new addition is gin, which they distil themselves. There are bottles in a rack with a dispenser. This is a little problematic when I am cooking. Chop some onions, fill glass, saute onions fill glass, etc.
  22. Brendon, you maybe should reflect on your own postings. As a new poster, you did rather come in quite aggressively. Many of us have been posting here for many years. I started posting in 2007. Although we have different views, here we can politely disagree and move on, instead of referring to "left wing turkeys" etc. I have often had disagreements with Nev, but I would never say this, and he would not say this about me because I don't make aggressive posts. You generally get what you give. T
  23. In most EVs I know of it is in front of you. My heater and demister switches on my old Ford Focus are not directly in front of me. Here is a picture of the primary display for a BYD
  24. By labour, I guess you mean Labor. Here is a breakdown of the levels of crime per state. Here is how the states and territories generally break down by safety and crime rates: Here is how the states and territories generally break down by safety and crime rates: Northern Territory: Highest per-capita crime rate nationally. Cities like Alice Springs and Darwin often top national per-capita crime lists. [1, 2, 3] Queensland: Has the highest crime rate among the major eastern states, with surging rates of assault, break-ins, and youth-related property crime. [1, 2, 3] Victoria: Frequently ranks highly on a per-capita basis, with recent statistics indicating record highs in criminal incidents—particularly in the Melbourne CBD and specific regional centres. [1, 2] New South Wales: Despite the high total volume of reported crimes (driven by its large population), its per-capita crime rates are relatively low compared to the rest of the country. [1, 2] Australian Capital Territory: Consistently considered one of the safest jurisdictions in Australia with significantly lower crime rates. [1, 2, 3] If you are making a connection between Labor governments and crime, you have to account for the fact that NSW has a low per capita crime rate. Is this an achievement of the NSW Labor government? The ACT has been governed by Labor since 2001 and has significantly lower crime. I am not spruiking for Labor here, I am not a party political person. In one of your posts you link to an ABC News site, which is lists all the crime stories. These are Australia-wide, not just Victorian. If you keep doomscrolling, of course, you will become anxious. I live in Victoria, and of course, I would like crime to be as low as possible; however, you have to keep things in perspective.
  25. Whilst I don't doubt that there are problems to be worked out, it is not insurmountable. Consider a sport such as wrestling or boxing. Within one gender, there is a range of sizes and weights. They don't pair up a 110kg competitor with a 60kg competitor. They have weight classes. The fact is that sport only works when it is competitive. We don't team up professionals with amateurs; it would not be interesting to watch. The point is that these problems have solutions. In any case, the sports argument is often that is presented is "what about sport" as if this is an argument against trans is and an argument about sports. Now personally, I have little interest sport however, I suspect these issues of competitiveness regarding gender are as solvable as problems of different weight and size, as well as experience.
