The Australian government is considering a request from Ukraine for more coal to the region to keep its electricity running over winter, the prime minister says.
Russia has targeted energy infrastructure in Ukraine, which has requested Australian shipments of coal so citizens don't freeze over colder months.
Prime Minister Anthony Albanese said the government was considering the request.
"We'll give consideration (to the coal request). I note the comments of the ambassador from Ukraine, who was talking about (shipments of coal) next October," he told reporters in Sydney.," he said.
"Next winter was what he was talking about."
The Department of Foreign Affairs and Trade has been in contact with the Ukrainian embassy following the request in December.
"Australia is helping empower Ukraine to end the war on its own terms," a spokesman said.
"We are in close contact with the Ukrainian embassy and our partners to ensure we are making the most effective contributions."
The federal opposition had urged the government to supply further coal to Ukraine as part of crucial energy support.
Opposition foreign spokesman Simon Birmingham said an offer to supply coal should have been made in Australia before winter.
"As late as it is, the Albanese government should immediately commit to continue crucial energy support to Ukraine," he said.
"(Ukraine's) war to defend their sovereignty from Russia's illegal invasion is also a significant test of democratic nations' resolve to defend international rules."
The previous coalition government pledged about 70,000 tonnes of thermal coal to Ukraine.
