Thousands of Australians in Lebanon are being warned to leave immediately as rocket exchanges with Israel narrow the window to escape safely.
Foreign Minister Penny Wong expressed alarm at the escalation of the conflict and called for Australians to get out, while spearheading a push to protect humanitarian workers in conflict zones better.
Australia was doing what it could to develop a contingency plan to get people out of Lebanon but numbers were "beyond the capacity of the government to provide assistance to all", she said.
