Those sorts of communications happen every day between staff - FYI emails cc emails etc - there's a sea of them, and what you quoted here relating to the Federal Minister's media adviser, an unspecified sender to the media adviser, "Victorian Border Force", Assistant Immigration Minister Michaela Cash and an apology from someone for not making it clear the ANF press release was to be published on the Friday.
This implies that the press release content had not been brought to the attention of the Minister, and the Prime Minister.
The Victorian Commander of ABF has publicly taken responsibility for the wording stuff up.
There's no suggestion that the Commisioner of the ABF in Canberra was aware of a problem, or had changed ANF operating procedures to include wandering the streets picking you and I, asking for our papers, or suggesting that the "innocent until proven guilty" convention had been changed.
Apart from any of that, there is a separation of powers between operations of the ABF, which is controlled by the Commissioner, and operation of the Government, which is controlled by the Parliament and through the Minister and Prime Minister. They can't just issue orders to the Commissioner to go out and kick some a*rse.
So yes, the plan to have ABF join the Victorian Police, Victorian Transport Police and Victorian Sheriff's Office at several hot spots was a Victorian plan.
