A pop star-inspired painting of one of Australia's most lethal fast bowlers has knocked over the judges' stumps at this year's Bald Archy Prize in Canberra.

The Bald Archy parodies Australia's top prize for portraiture, the Archibald Prize, promoting comedy, cartoons and caricatures.

Mitchell Johnson's 37 wickets in Australia's recent 5-0 Ashes whitewash tore the heart out of England's batting order.

Winning artist Judy Nadin from Newcastle, New South Wales, saw Johnson's deliveries more like a wrecking ball and drew inspiration from American pop star Miley Cyrus's eponymous music video.

Ms Nadin says her winning caricature has a feminine touch.

"I happened to get a couple of my friends to pose for me so maybe that's why it's got a bit of a feminine element, but Mitchell's kind of a sexy guy," she said.

"I did put hairs on the legs though, so that butched him up a little bit."

Ms Nadin says she initially considered another famous cricketer for her subject.

"At first I thought I might do Michael Clarke, but then I thought, no I have to do Mitchell Johnson.

"Just the 'stache' that he grew and his face is interesting - nice and elongated and the steeliness in his eyes."

But Ms Nadin admits she is not a die-hard cricket fan.

"I did jump on the bandwagon for the Ashes; I like Mitchell's fire and spirit and the fact that we beat the Poms," she said.

"I'll jump off the bandwagon now that the cricket's over - I'm more of a tennis fan."

Ms Nadin is a graphic designer who submitted three entries to the Bald Archy competition for 2014.

Her two other caricatures portray famous figures Cate Blanchett and Tina Arena.

Ms Nadin won the Bald Archy Prize in 2010 for her entry Patti's Cake, featuring Australian entertainer Bert Newton.

The best of the finalists will go on tour nationwide from March, but are currently on display at the Watson Art Centre in Canberra.
