Australia offers Ukrainians refuge
Australia has offered temporary refuge to visiting Ukrainians due to soon return to their country, which is in turmoil.
Russian troops control the Crimea region of Ukraine amid concerns the country could be close to war.
Ms Bishop described the situation in Ukraine as "highly charged and volatile".
She said: "We are concerned by reports that Russia has increased its military presence in Crimea.
"We reiterate our view that Russia's aggressive acts against Ukraine, an independent sovereign nation, are totally unacceptable."
The Australian government did not say how long visas would be extended, nor did it immediately provide figures on how many Ukrainians might be eligible to extend their stays.
