Senator PATRICK (South Australia) (14:23): Minister, what happened to Northern Endeavour could well happen to some of ExxonMobil's assets in the Bass Strait, which it is trying to offload. ExxonMobil has earned $42 billion in revenue over the past five tax transparency years and not paid a brass razoo in tax and would be seeking to devolve itself of responsibilities for the assets that were used to generate this tax-free revenue. The cost to the taxpayer could be billions. What is the government doing to prevent this from happening?
