Artist Linda Klarfeld, who was previously commissioned to create Prime Minister Tony Abbott's bust, said she hoped to have the sculpture unveiled by June.

"It's always incredibly exciting, everyone you do is a completely different face. This was a more informal meeting which I enjoyed," Ms Klarfeld said.

"He let me do my thing, he was very charming and accommodating. I'm hoping to persuade him to come into my studio to have a sitting as well, which would be a first for me."

Ms Klarfeld said she create the sculpture by doing a "mini-bus" in plasticine. She said she uses it purely as a reference, rather than enlarging the model.

"I've already started, but it will take about six weeks at the foundry," she said.

"This is something that has been happening for more than 100 years. I love knowing that I'm part of Australian history."

Mr Turnbull's bronze bust will become the latest addition to the Prime Minister's Avenue. It currently feature bronze portrait busts of each of the previous 28 Prime Ministers of Australia.

The Avenue was officially opened by the Governor of Victoria, Sir Winston Dugan on March 2, 1940 who unveiled the busts of the first six Prime Ministers'.

The first 12 busts in the Prime Minister's Avenue were a gift to the people of Ballarat from prominent local benefactor and Member of Parliament, Richard Armstrong Crouch, who left a further bequest to ensure the continuation of the Avenue after his death.
