Foreign Minister Julie Bishop says no Australians have been confirmed killed or injured in the Paris attacks but the situation is very fluid.
Ms Bishop told reporters in Perth on Saturday that she has spoken with Prime Minister Malcolm Turnbull, who is in Berlin, in the wake of multiple terrorist attacks in Paris overnight. 
"The death toll is rising, the situation is very fluid," she said. "The siege at the Batalcan Concert Hall has just ended. I understand it was a rock concert, it was anticipated that many Europeans would be at this concert.
"The concert hall has a capacity of perhaps up 1500, I understand that when the two two terrorists entered, many people were able to escape but not all. So the circumstances have been absolutely tragic and horrifying."
Ms Bishop said the death toll was about 112 but the official figures for the Batalcan Concert Hall vary between 70 and 100.
"This is indeed a black Friday for France and for the world," she said.
Opposition leader Bill Shorten said the "people of Paris are in our thoughts" and Australian Greens Leader Dr Richard Di Natale expressed his deepest sympathies.
There are 2500 Australians registered as being in France but the actual number may be much higher.
"There are no reports of any Australians killed or injured at this stage," Ms Bishop said.
ASIO's national threat assessment centre is monitoring the situation to assess whether there needs to be security changes in Australia, Ms Bishop said.
"At this stage we do not intend to change the threat level," she said.
Australia has offered all assistance to France, she said.
"We stand in solidarity with the French people in condemning these horrific and devastating attacks.
"No organisation has yet claimed responsibility. We don't know who has carried out these horrendous attacks on innocent people but it certainly has all the hallmarks of the terrorist attacks we've seen in recent times by ISIL, Daesh and similar organisations."
The minister urged Australians in Paris to "stay put, stay safe" and get in contact with the consulate on1300 555 135.
