Foreign Minister Julie Bishop is attending her fourth AFL grand final in as many years at the taxpayers expense after being the star attraction at two Liberal party events since she arrived in Melbourne on Thursday.

On Saturday morning North Melbourne AFL chairman Ben Buckley joked to a packed grand final breakfast audience including Ms Bishop that she "had arranged a meeting of cabinet in the Yarra Room at the MCG regarding the North Korean crisis".

A spokeswoman for Ms Bishop said it was appropriate for senior leaders from all parties to attend the AFL grand final in their official capacities. When politicians are in their official roles, taxpayers fund travel and other expenses.

"I have no concerns at all by the attempt at humour because all of my travel expenses are consistent with the guidelines for parliamentarians," Ms Bishop said in response to Mr Buckley's comments.
