Warren is well known for his editorial cartoons, his appearances on radio and television, as well as being an author and adventurer.

He has been the full-time editorial cartoonist for the Sydney Daily Mirror, Daily Telegraph Mirror, The Daily Telegraph and Sunday Telegraph newspapers since 1986 and had accrued many awards including three times winner of the Australian Cartoonists’ Association Cartoonist of the Year.

Goulburn Mulwaree Mayor Geoff Kettle said Mr Brown was a great choice to be the city’s Australia Day Ambassador.

“Warren was chosen as our Australia Day Ambassador because he is a local to the district,” he said.

“He is also a particularly appropriate choice for 2015 because he is continuing in his role as the overnight host at Gallipoli on ANZAC Day and the pre-service host for the service at the Australian War Cemetery at Lone Pine.”

Since 2006 Warren has been the overnight host at Gallipoli on Anzac Day and the pre-service host for the service at the Australian war cemetery at Lone Pine.

In 2010, he was appointed a Commissioner on the National Commission for the Commemoration of the Anzac Centenary – a six-person committee which included former Prime Ministers Malcolm Fraser and Bob Hawke, to deliver a report to the Prime Minister as to how Australia would commemorate the centenary of the landings at Gallipoli in 2015 – and a four-year program of commemoration from 2014 to 2018.

He was appointed a member of the subsequent Anzac Centenary Task Force headed by Air Chief Marshal Angus Houston for Commemorative and Ceremonial – and the Creative committees. His role continues at Gallipoli in 2015.

Warren has written several books – his most recent is the biography of the Australian motorist and adventurer Francis Birtles. He lives with his wife Tanya and seven year-old son at Middle Arm near Goulburn.
