Australians stranded in Israel have been given fresh hope as the government announces more evacuation flights after scheduled repatriation ones were cancelled due to security concerns.
The multiple flights on Sunday will be a mixture of chartered and air force planes, Foreign Minister Penny Wong said.
But flights "remain subject to factors including the security environment", she told reporters in Adelaide on Sunday.
"The situation in Israel in the occupied Palestinian territories continues to change rapidly."
The government is also working with commercial carriers to help Australians get home from Dubai after leaving Israel.
Australians in Lebanon are now being told to reconsider whether their need to stay is absolutely essential.
About 1540 Australians in Israel and Palestine have registered with the foreign affairs department but some 300 have registered for information only.
A further 939 Australians who had previously registered have already left Israel.
Australian Defence Force planes are on standby in the region to evacuate citizens with hundreds of Australians in Israel wanting to leave.
Two scheduled flights over the weekend were scrapped as the Australian government assured people affected it was doing everything possible to bring them safely home.
Australians have been told if they have other options to leave, they should take them.
Defence Minister Richard Marles said the government continued to look at all available options to get Australian citizens to safety but some things are out of its control, such as if Israel closes its airspace.
"We are positioned, we have the intent to put in place flights very soon, almost immediately," he told the ABC's Insiders program on Sunday.
Hamas reportedly fired a rocket that landed near Israel's main airport on Saturday night, just hours after the repatriation flights were cancelled.
The Palestinian militant group is expected to make the airport a major target as Israel prepares to launch a full scale ground offensive in Gaza.
Senator Wong reiterated Australia's support for Israel's right to defend itself but called on the government to act within the rules of war.
"Israel's right to defend itself and secure its borders is legitimate but ... I would also urge for the observation of international humanitarian law because civilians on all sides are being harmed and that is a very distressing situation," she said.
Mr Marles made the same point but added he believed Israel was acting within the rules when asked about Tel Aviv cutting access to food, water and electricity to Gaza.
"I'm not casting a negative judgment on what they're doing," he said.
"But ... I'm not sitting in their control room either, I don't have all the information available to me that they will have to them."
The Australian government has announced $10 million in humanitarian assistance for civilians in Gaza.
This includes $3 million to the Red Cross for services such as urgent medical supplies and a further $7 million for emergency water, sanitation, hygiene services and child protection through United Nations agencies.
The foreign minister also called for unimpeded access for innocent civilians to leave Gaza after a proposed window for approved foreign nationals to leave didn't eventuate.
Senator Wong said she was doing everything she could to allow Australians who wish to leave Gaza to be able to do so through Egypt.
The Rafah crossing remains closed.
"We support work being done by Egypt and others to make the crossing available for humanitarian purposes including the outward passage of civilians," Senator Wong said.
"We have engaged, including me personally, with our Egyptian counterparts and the Israelis to this end."
