Another Australian government-assisted flight will leave Israel for Dubai if deteriorating security conditions allow.

Foreign Minister Penny Wong has warned Australians to leave Israel and take any opportunity possible as the situation remains “highly challenging and rapidly changing”.

Seats on a number of repatriation flights had been left empty despite all of them being allocated, the foreign minister said.

More than 1500 Australians registered with the foreign affairs department have left Israel and occupied Palestinian territories.

About 1200 Australians are in contact with the government and are receiving updates about returning home.

Australia is also helping schedule onward departures from London and Dubai to Australia, with 222 people – including 164 Australians – landing in Sydney on an assisted flight on Tuesday night.

A Qantas flight left London on Tuesday night and is due to land in Sydney on Wednesday evening with about 300 passengers on board.

The government is also working to support Australians to leave the West Bank as it liaises with international partners to arrange transport to Jordan.

The safety of the 46 Australians in Gaza remains unknown after a barrage of Israeli rockets hit the territory.

The Department of Foreign Affairs and Trade has been contacted for comment.

The evacuations come as hundreds of civilians were killed in a blast at a Gaza hospital, which authorities in the Hamas-run enclave blamed on an Israeli air strike but the Israeli military blamed on a failed rocket launch by Palestinian militants.

The blast was the bloodiest single incident in Gaza since Israel launched a bombing campaign against the territory in retaliation for a deadly cross-border assault by Hamas in southern Israel on October 7.

Israel’s blockage of water, food and fuel is also making the situation in Gaza more dire as hospitals warn of a worsening humanitarian crisis when emergency generators run out of fuel and cut electricity.

Australia’s terror threat level remains unchanged, but Australian intelligence chief Mike Burgess says ASIO anticipates “spontaneous violence” as anti-Semitic and Islamophobic attacks reverberate around the world.

The foreign minister is also working with regional partners to open a humanitarian corridor at the Rafah crossing into Egypt to secure safe passage from Gaza.

The US secretary of state is in the Middle East and working to broker a solution as President Joe Biden touches down in Israel on Wednesday.

DFAT remains in direct contact with Australians seeking to leave Gaza and they have been told to be ready in case the humanitarian corridor eventuates as it may not stay open for long.

“We support the work of the US, Egypt and others to open the Rafah crossing for humanitarian purposes,” Senator Wong wrote on X, formerly known as Twitter.

Australian parliamentarians have also expressed their support for the people of Israel after the Hamas terrorist attack.

The government, opposition and independent MPs voted in support of a motion to unequivocally condemn the attack against Israel, reaffirm its right to defend itself and call for the immediate release of all hostages.

They also acknowledged the “devastating loss of Israeli and Palestinian life” from the attacks and that the events were deeply distressing to Australian communities.

A Greens push to condemn Israeli war crimes and call for an end to the war and occupation of Palestinian territories failed. The minor party subsequently voted against the Israeli support motion.
