DHAKA: Australia is to toughen citizenship laws and tackle those inciting hatred under new measures targeting domestic extremists.

PM Tony Abbott has said, reports the BBC.

He said citizenship for dual nationals involved in terrorism could be suspended or even revoked.

People born in Australia could also lose some privileges if they broke anti-terror laws, he added.

Officials have warned that the country faces a growing security threat from radical Islamists.

Dozens of Australian nationals are thought to be fighting for Islamic State (IS) militants in Iraq and Syria.

Experts are worried about the effect of returnees - and on those who support them - on domestic security.

‘It has long been the case that people who fight against Australia forfeit their citizenship,’ Abbott said in a speech at the federal police headquarters in the capital, Canberra.

‘So Australians who take up arms with terrorist groups, especially while Australian military personnel are engaged in Afghanistan and Iraq, have sided against our country. And should be treated accordingly,’ he said.

For dual nationals, that meant revoking or suspending citizenship, he said, and the government was also looking at measures targeting Australian nationals involved in terrorism.

‘These could include restricting the ability to leave or return to Australia, and access to consular services overseas, as well as access to welfare payments.’
