Australia joined 67 other countries in Washington to discuss the future of the international coalition's battle against the self-proclaimed Islamic State.
The United States hosted the event - the first of its kind since the election of President Donald Trump late last year.
Secretary of State Rex Tillerson told those gathered that defeating IS is the United States' top goal in the Middle East.
He said the next phase of action would be to establish safe zones to help refugees from conflict areas return home.
"While a more defined course of action in Syria is still coming together, I can say the United States will increase our pressure on ISIS and Al-Qaeda and work to establish interim zones of stability through ceasefires to allow refugees to go home."
It is not yet clear how the proposed "interim zones of stability" would work, and they are not mentioned in a statement at the conclusion of the meeting.
Secretary Tillerson also urged member states of the coalition against IS to increase their commitment to the joint military efforts.
"It is the policy of the United States to demolish and destroy this barbaric terrorist organisation. That is what we're going to do. The United States will do its part, but the circumstances on the ground require more from all of you, especially in regard to contribution to military and financial resources."
The Foreign Minister Julie Bishop told the ABC Australia is prepared to consider any specific requests from anti-IS coalition partners.
But she says Australia's contribution in the region is already considerable.
"We haven't been asked to provide anything specifically, but if there were a request to provide something specific, we would of course consider it. There have been requests for further funding and I will certainly take that into account in the context of our budget. But the point I'm making is Australia has already contributed $500 million, committed and provided $500 million, to the effort, particularly the humanitarian effort in Syria and Iraq and the countries around Syria and Iraq."
Hungary, meanwhile, has already announced plans to increase its troop presence in Iraq from 150 to 200.
Foreign Minister, Peter Szijjarto welcomed the US aspiration to bring about what it calls a complete defeat of IS, also known as ISIS.
"We are enthusiastic about the new U.S. strategy to defeat ISIS. We think that we must not relax until we totally eliminate ISIS. ISIS with its brutal acts, with its attacks, put a direct security hazard on Europe, including Hungary."
As Islamic State loses ground in Iraq and Syria, there are fears so-called foreign fighters will attempt to return to their home countries, possibly to launch attacks.
Julie Bishop says Australia is working with countries in the Middle East, Europe and Asia to track people who, it is deemed, could pose a threat.
