Julia Gillard will be quizzed on her achievements as the country's first female prime minister and her defeat during a public interview with journalist Anne Summers in Sydney on Monday.

Australia's first female prime minister has agreed to be the inaugural guest of the Anne Summers Conversations, which will be held at the Sydney Opera House on Monday night.
The event will run for 90 minutes including an hour long interview and 30 minutes of questioning from the audience.
A similar event will be held at Melbourne Town Hall on Tuesday.

Ms Gillard revealed this month she was writing her memoir to be published in October 2014.
