Former Foreign Minister Julie Bishop has revealed her surprise that no federal deputy from Washington voted for her in the leadership vote last week, and says she was caught in an "incredible conflict" within the Liberal Party.
The former Liberal vice president also said he believes there is a Queensland influence on the federal party.
Speaking about her decision to resign as foreign minister, Ms. Bishop did not deny being told she was not wanted in the new Scott Morrison cabinet, Post Newspapers in Perth reported.
"I just felt it was better not to be part of that cabinet," Mrs. Bishop told the newspaper.
The 62-year-old woman did not say if her position was offered to another person in exchange for a vote.
"I'm sure someone else could say," she said, adding that "she got caught in" an "incredible conflict between the left and the right of my party."
Ms. Bishop, who will remain in parliament on the bench as a member of Perth's headquarters in Curtin, expressed surprise at the fact that none of the other 11 federal deputies in Washington voted for her in the August 24 vote. .
"I was surprised," he said.
"I always believed that Western Australians had a responsibility to look after the interests of this state.
"Without doubt there is an influence of Queensland, there is no doubt".
Ms. Bishop said she believed that she had the depth and political experience for the main job, and the ability to put together a good team.
But she was also comfortable with the decisions she had made, and now she will focus on her campaign for Curtin in next year's election.
Ms. Bishop launched a failed offer to replace Malcolm Turnbull as prime minister on August 24, but was knocked out in the first round of voting for the Liberal leadership.
Scott Morrison beat Peter Dutton in the final showdown to become prime minister.
Ms. Bishop resigned as foreign minister two days later, after five years in office and more than a decade as vice president of the Liberals.
