Following her return to Australia in 2006, Overington gained a position as senior journalist with the News Limited newspaper The Australian. She covered the AWB scandal, in which AWB Limited (formerly the Australian Wheat Board), owned by the Australian Government, paid $290 million in kickbacks to the regime of Saddam Hussein, in contravention of the United Nations Oil-for-Food Humanitarian Program. Overington's book Kickback: Inside the Australian Wheat Board Scandal, released by Allen & Unwin in 2007, provided an account of the scandal.
