Is it just not possible to hold these companies accountable for anything?

Just make a rule that a company will be taxed on its local revune assuming it made profits equal to it's most profitable "related party". Eg, Adani Ireland has 30% profit, then we assume Adani Australia's revenue includes 30% profit and we tax that.

Absolute shocker. This has never happened before and is completely unexpected!

Capitalism never works.

“Did you think we were going to pay $22billion in tax?”

“We paid $22billion to a lobbying firm who bribed the previous government MP with a pittance to pass legislation that is beneficial to us but detrimental to the Australian People and also the Environment.”

“Also, the lobbying firm is a subsidiary of ours so we can keep the money in the company”
