Parliament house could be evicted from the five dollar note to make room for the face of charity crusader Fred Hollows.
Former Prime Minister Bob Hawke, Olympian Cathy Freeman and Mr Hollows' widow Gabi gathered at Sydney Opera House on Monday to launch the "Get Fred on the Fiver" campaign.
Former chairman of the Foundation and broadcaster Ray Martin said it was fitting that Fred Hollows be on the note.
"The fiver and Fred is almost as one, we had the `Fiver for Fred' campaign because a fiver meant we could buy a lens to allow a cataract blind person to see," he said.
"There are five million people who in the world can see because of his inspirational idea."
Fred Hollows Foundation chief executive Brian Doolan said he welcomed other Australians of the Year being featured on notes, listing Rosie Batty as a prime candidate.
