Israel blocking Gaza aid against international law: PM

"The humanitarian suffering in Gaza has reached unimaginable levels. Famine is unfolding before our eyes," the statement said.

"Humanitarian space must be protected and aid should never be politicised."

Prime Minister Anthony Albanese said Israel's actions in blocking aid to the region was "not defensible".

"It's certainly not something that's consistent with international law," he told ABC radio on Wednesday.

"We're also seeing people killed while trying to get access to food and water. Now, in 2025 that's completely unacceptable.

"It is an affront to common decency and community humanity what is happening in Gaza."

Israel has denied responsibility for the lack of food in the Gaza Strip, accusing Hamas of stealing aid shipments.

It has also denied there is starvation among the population, although it has throttled the flow of food to Gaza for months, according to international human rights groups.

The prime minister's latest comments come two days after he announced Australia would recognise Palestinian statehood at September's UN General Assembly, joining the UK, France and Canada in the move.

The shift means Australia's foreign policy has diverged from that of the US, a key ally that has for decades opposed formal recognition of Palestine.

However, the White House has declined to directly criticise Australia for its actions in recognising Palestine after US President Donald Trump suggested a similar move from Canada could affect trade talks.

A spokesman told Nine newspapers the president had an open mind on the status of Palestine, despite not backing statehood.

Mr Albanese said the US would have a critical role to play in peace talks.

"One of the things that has defined president Trump's position internationally on global affairs is that he is an advocate for peace and he's been an advocate for peace in the Middle East for a long period of time," he said.

While some have argued Australia's decision to break from the US could imperil the bilateral relationship, Flinders University international relations expert Jessica Genauer said the government's diplomatic calculus had helped dampen any impact.

"Because Australia waited until other important countries all said they're planning to recognise Palestine ... I don't think it will be singled out by the US," Dr Genauer told AAP.

"The Trump administration is opposed to countries recognising Palestine, but I think that they would put Australia in with a whole group of other countries and it wouldn't particularly be detrimental to Australia's relationship."

Australia will join more than 140 UN member states in recognising Palestine, but Opposition Leader Sussan Ley said the prime minister's priorities were wrong.

"He's clearly distracted by what he's been talking about now for weeks with respect to Palestinian recognition, that is actually not going to make the world a safer place," she told Seven's Sunrise program.

The coalition has pledged to reverse the recognition decision should it win the next election.

Crossbench senator Fatima Payman, who defected from Labor in 2024 after criticising the government's stance on the Middle East, said recognising statehood was overdue but could not be an end point.

"Symbolism matters, but saving lives matters more so when we're thinking about what Australia needs to do next, it's to make sure that they keep that pressure on Israel," she told ABC radio.
