Well the funeral companies costs would certainly have increased on July 1 so their fees could be expected to rise some degree or are you just disputing the amount? The power costs are higher, superannuation is higher, A/C install & servicing much higher and so it goes on for all Australian businesses. I wonder about the crematorium aspect also; not sure how these are powered? The local aluminium in the Jabiru engines just went up by $380 per tonne.
The carbon tax is a reverse tariff - it taxes local business without harming imported goods or services.
