In 2018 the Department of Infrastructure paid 10 times the appropriate amount for a triangle of land near the proposed Western Sydney Airport, providing a windfall to a significant Coalition donor.

The government department then behaved unethically when the Australian National Audit Office (ANAO) investigated the matter.

It's not clear from the ANAO's remarkable report on the scandal why exactly this happened. What is somewhat clearer is the how of the process.
