Australia is playing a role in a review by the United States of the battle against Islamic State, says Foreign Minister Julie Bishop.
Ms Bishop met for almost an hour with US Vice President Mike Pence at the White House on Wednesday, in what was the highest-level personal contact between Australia and the new Trump administration since the presidential inauguration in January.
She said Australia had not been asked to boost its contribution to the battle in Iraq and Syria, but was assisting in a review.
"There is a review in the United States under way as to the strategy for defeating ISIS and I gave some input into the Vice President's thinking," she told reporters in Washington after the meeting.
She said foreign fighters leaving Iraq and Syria was a concern for both the US and Australia.

"We have to look at post-defeat of ISIS environments and scenarios," the minister said.
Ms Bishop said the fact that the meeting went longer than scheduled was "a good sign" of strong relations with the Trump administration.
The relationship got off to a bumpy start with the leaking of details of a phone call between President Trump and Prime Minister Malcolm Turnbull, in which the president described a refugee deal as "dumb".
On Afghanistan, Ms Bishop said Australia's current military contribution was considered "appropriate".
She expected there would be opportunities this year for Mr Turnbull to meet face-to-face with Mr Trump, but would not go into details.
She was hopeful Mr Pence would visit Australia during an expected tour of the Asia-Pacific region by the vice president.
Ms Bishop said she understood the US wanted to have a "constructive" relationship with China.
