Foreign Minister Julie Bishop says she's not interested in a high profile domestic portfolio in Malcolm Turnbull's looming frontbench reshuffle, saying she still has work to do overseas.

As the Liberal Party's deputy leader, convention states Ms Bishop can choose her frontbench position, but there have been reports she is coming under pressure from colleagues to take a portfolio considered more central to the government's domestic political fortunes.

Speaking on ABC radio on Wednesday, Ms Bishop said she was not concerned about the reports.
