Only one woman has occupied The Prime Minister's Chair in Australia. Who was she?

Julia Gillard is the current Prime Minister of Australia.
She is the first and only women to hold the position. Gillard is also the leader of the
Australian Labor Party. She first assumed the role of PM after Kevin Rudd, the former PM
and head of the Labor Party, lost the support of his party and was forced out, in 2010.
Shorty after this Gillard maintained power after the 2010
election.

Gillard was first elected to the House of
Representatives in 1998. She represented Lalor, Victoria. She has risen steadily
throughout her party and politics in general, serving in a variety of positions prior to
her becoming PM. She filled roles as a member of the shadow cabinet, deputy leader of
the opposition, and deputy prime minister.
