Australia's Prime Minister Julia Gillard has been sworn into office, making her the first woman elected to the post in the nation's history.

澳大利亚总理茱莉亚·吉拉德已宣誓就职，是该国历史上第一位通过竞选产生的女首相。

Ms Gillard heads a minority government with the backing of Greens and independent MPs

She called an election after ousting¹ former PM Kevin Rudd in an internal Labor² party revolt in June.

Last month's poll produced a hung parliament, forcing Ms Gillard to seek the backing of independents and Greens to form a government.

Mr Rudd has been sworn in as foreign minister.

"I, Julia Eileen Gillard, do solemnly（庄严地，严肃地） and sincerely affirm and declare that I will loyally serve the Commonwealth³ of Australia in the office of prime minister," she said in the ceremony in the Australian capital, Canberra.

Her cabinet includes her deputy, Treasurer⁴ Wayne Swan, and former pop star Peter Garrett, who switches from environment to education. Former Foreign Minister Stephen Smith moves to defence.

Analysts⁵ say her majority of one in the 150-seat lower house of parliament will force Ms Gillard to negotiate issue-by-issue with the opposition⁶ Liberals.

Ms Gillard has promised a 30% tax on iron ore（铁矿石） and coal mining companies' profits, a tax on major polluters to help cut carbon emissions⁷ by 5% in 10 years and a broadband network for rural areas.
