Professor Michael Dirkis says the use of the departure prohibition order by the Ausralian Taxation Office (ATO) on actor, Paul Hogan is an example of its increase in recent years under Project Wickenby.

In an article published in the Australian Financial Review, Professor Dirkis says he could see why such orders were necessary because most countries have a prohibition on collecting foreign debts.

"The only country where the ATO may pursue debt is New Zealand," he asserts.
