Australia is stepping up its support for Ukraine with a new $75 million aid package as fighting intensifies in the country.
The Federal Government today announced it will send more weapons, humanitarian supplies and coal to Ukraine as the fourth week of the Russian invasion begins.
The 70,000 tonnes of coal is being sent after Ukrainian authorities requested it to help keep the country's electricity grid running.

That request came after Russian forces captured Ukraine's largest nuclear power station.
Meanwhile, there are fears scores of Ukrainian soldiers have been killed and many others are trapped under rubble following a Russian attack on a military base in Mykolaiv in south-east Ukraine.
There were 200 soldiers sleeping in the barracks when missiles hit the base.
Dozens of troops are reported to have been killed in the attack.
It is believed Russian warplanes dropped five bombs on the base.
Rescuers at the scene have been using shovels and their bare hands to free survivors from the rubble of the buildings.
CNN Swedish affiliate Expressen quoted one of the surviving soldiers, 54-year-old Serhil, who was sleeping in the barracks opposite where the attack hit, as saying, "of the approximately 200 who were there, I would guess about 90 per cent did not survive."

"Glass flew everywhere. I prayed to God that I would have time to take shelter before more bombs came. There are always more bombs," Nikita, a 22-year-old Ukrainian soldier, said.
Mykolaiv, a southern city that sits along the Black Sea, has been a frequent target of Russian attacks.
It is seen as a strategic target for Russian land forces in any move to capture Ukraine's third-largest city, Odesa, which lies further west along the coast.
The attack on the barracks came after US officials confirmed that Russia launched hypersonic missiles against Ukraine last week, the first known use of such missiles in combat.
Russia's Ministry of Defence said on Saturday a powerful hypersonic "Kinzhal" missile destroyed a military ammunitions warehouse in western Ukraine on Friday.
