Cartoonist Bill Leak has died of a suspected heart attack.
Leak, 61, died on Friday morning in Gosford Hospital, The Australian reported.
"We will miss him dreadfully and our hearts go out to his wife Goong, his stepdaughter Tasha and his sons Johannes and Jasper," The Australian's Editor-in-Chief Paul Whittaker said.

Leak was known for his highly controversial cartoons -- including one that depicted an aboriginal father, beer can in hand, asking a policeman what his own son's name was.
He was also a vocal opponent of section 18c of the Racial Discrimination Act and was last year accused of being racist over the cartoon.

"I think 18C is an abomination. Look, I can only assume that a lot of people genuinely believe that freedom of speech means the legal right to hurl abuse. In fact, nothing could be further from the truth," he told the ABC in October last year.
"Freedom of speech is what created our civil and free society. It is all about the exchange of ideas, about letting people express their views in the marketplace of ideas."
