Career
He is the daily editorial cartoonist on The Australian newspaper. These included portraits of Donald Bradman in 1989, Malcolm Turnbull in 1994, Graham Richardson in 1995, Tex Perkins in 1997, Gough Whitlam in 1998, Sir Les Patterson in 2000 and Robert Hughes in 2001. He was interviewed in the 2005 Peter Berner documentary about the Archibald Prize called Loaded Brush.
In 2007 he ran into trouble by portraying the then leader of the opposition Kevin Rudd as Tintin (accompanied by Snowy).
This was resolved by Leak promising to not profit from any sales of cartoons from this series. On 18 October 2008 he sustained serious head injuries in a fall and, while his outlook was initially poor, he recovered.
Leak"s television series, Face Painting, in which he paints portraits of people who have died, went to air on the American Broadcasting Company in November 2008. A cartoon of his, commenting on the 2015 United Nations Climate Change Conference, published in The Australian in December 2015, generated controversy over its allegedly racist content.
