Foreign Minister Julie Bishop says the bomb attacks in Brussels show that no country is immune to terrorist atrocities.
The Australian government has offered its support to the Belgian government to help in any way to track down those responsible for the "atrocious attacks" that have killed at least 30 people.
Ms Bishop said they have no information at this stage to suggest that any Australians had been involved or caught up in the attacks.
She urged Australians in the country to stay calm and continue to follow travel advice.

"There has been a lot of contact between our intelligence and law enforcement agencies and Australian border force to make sure that we can keep Australian airports secure and that is obviously an ongoing job," he told reporters in Bali.
"This threat has been around for a long time and will continue to be around for a long time."
