Lawyer Frank Costigan has been named in a list of the top 100 Irish Australians of all time.
The Irish Echo, an Australian newspaper for the Irish community, has compiled the list to celebrate its 20th anniversary and showcase the contribution Irish migrants and their descendents have made to Australia since the arrival of the First Fleet.
Costigan was a Queen's Counsel and is most famous for chairing the Costigan Commission, which investigated organised crime and tax evasion in the early 1980s.
He also chaired the anti-corruption agency Transparency International in Australia.
He passed away in Melbourne in April at the age of 78.
