"There is the possibility for Ukraine to buy Australian uranium for our nuclear power stations."
Mr Abbott said energy security was an important issue for Ukraine and the country faced difficulties in shoring up supplies of coal and uranium.
"This would be good should we be able to bring it about for jobs and prosperity in Australia as well as for jobs and prosperity in the Ukraine," Mr Abbott said.
