The controversial menu was presented at a dinner hosted by opposition Liberal Party leader Mal Brough, an ex-minister under former Prime Minister John Howard.
Gillard, 51, has described the menu as a "grossly sexist and offensive". The leader ruling Labor Party said the menu follows a "pattern of behaviour" from the opposition party.
Opposition leader Tony "Abbott's solution to this pattern of behaviour is not to show any leadership. I mean, he's effectively stood by Brough," Gillard was quoted as saying by ABC News.
The opposition party was forced on to the back foot in the row over sexism in politics after the menu, which contains crude references to Gillard's body emerged online.

Abbott condemned the use of the menu card, but said it should "absolutely not" cast doubt on Brough's pre-selection for the Sunshine Coast seat of Fisher.
"I think we should all be bigger and better than that; whether it's a tacky, scatological menu out the front of a Liberal Party event, whether it's squalid jokes told at union conference dinners with ministers present," he said.
Opposition Treasury spokesman Joe Hockey was the guest of honour at the dinner for about 20 people hosted by Brough in Brisbane on March 28.
