A dual national abroad can be stripped of their citizenship without a conviction if they are deemed to be "engaged in relevant conduct", or they had engaged in such conduct in Australia but left for overseas before being charged or brought to trial.

Also removed is the proposal to include as an offence the destruction or damaging of government property, which could have left common vandals prone to deportation.

The new proposals, however, do recommend that the laws be applied retrospectively to anyone who has been convicted of terrorist offences within the past decade and given a jail sentence of 10 years or more.

This potentially applies to seven dual nationals currently doing time in relation to three separate plots that were foiled.

Intelligence showed that militants connected with Islamic State were planning to behead a member of the public in Australia, Prime Minister Tony Abbott said on Thursday after hundreds of police raided homes in a sweeping counter-terrorism operation. More than 800 police were involved in the pre-dawn security operation in Sydney and Brisbane, described as the largest in Australian history. At least 15 people had been detained, police told a news conference.

These were the plan to attack the Holsworthy military barracks, the plot to attack public sites in Melbourne and Sydney as uncovered by Operation Pendennis, and Faheem Lodhi, a Pakistani-Australian jailed for conspiring with Willie Brigitte to bomb the power grid and three military facilities.

The committee of 11 MPs acknowledged there was internal controversy over the retrospectivity and said it should be applied "with great caution and following careful deliberation, with regard to the nation as a whole".

Prime Minister Tony Abbott supported retrospectivity while his deputy, Foreign Minister Julie Bishop, said she opposed it in principle but could accept retrospectivity if applied on a limited basis.


Ultimately, all 27 recommendations were backed on a bipartisan basis and Mr Dutton indicated all would be adopted by the government.

The original proposals for stripping citizenship were deemed unconstitutional. Even though the laws have been pared back, legal experts who appeared before the committee said they would be vulnerable to a High Court challenge.

Attorney-General George Brandis refused to give the committee a copy of advice from the Solicitor-General countering this view but sent the committee a letter vouching for the constitutionality of the laws.

A minority of committee members remained concerned but, in recommending the laws be passed, agreed the government would bear the responsibility should they be successfully challenged.

Shadow attorney-general Mark Dreyfus said the constitutionality of the laws or otherwise was now the government's responsibility.

"Despite requests by Labor, the government refused to release its legal advice to the committee. The government has assured the committee that it believes the bill will withstand constitutional challenge," he said.​
