Liberal Senator Sue Boyce is shocked and embarrassed there is only one female cabinet minister in the incoming Abbott government.

Prime Minister-elect Tony Abbott unveiled his ministerial line up on Monday, revealing the only woman in the cabinet is Foreign Affairs Minister Julie Bishop.

Senator Boyce, who is retiring from parliament when her term in the Senate expires next July, said the lack of women in cabinet should be a wake up call for the Liberal Party.

"It's a systemic problem for our party," Senator Boyce said in a statement.

"It's a shame that this shocking and embarrassing statistic will permanently tarnish a wonderful victory."

Senator Boyce urged the party to reform preselection processes in order to foster the depth of talent to ensure both women and men take on senior roles.

She also had a crack at the coalition's preselection process in her home state of Queensland where only six out of 30 candidates were women.
