Australians entering declared terrorist hotspots will face strict penalties upon their return, as the government extends laws cracking down on foreign fighters.
Provisions allowing a minister to declare an overseas zone and ban Australians who have visited the area from returning are set to be extended for an extra three years, after laws cleared the lower house on Monday.
The laws are due to expire in September, but the federal government is seeking to extend the measure for three years until 2027.
No areas overseas are currently listed as a declared area, although provinces in Iraq and Syria have previously been named as hotspots.
The laws were originally drafted in response to the threat of the terrorist group Islamic State and fears Australians could travel overseas and enlist.
Four people have been charged with offences since the laws were created.
Independent MP Zoe Daniel said the laws were out of date, with no hotspots being declared after they were used to combat foreign fighters joining Islamic State.
Ms Daniel questioned whether the laws would be rolled over forever.
Chair of parliament's intelligence and security committee Peter Khalil rejected Ms Daniel's characterisation, saying the laws weren't put in place to deal with a single, specific threat.
"The law itself pertains to the government making an assessment and declaring an area and that could be for many other reasons, many other terrorist groups," he told AAP.
Attorney-General Mark Dreyfus said the extension was necessary to prepare for future threats.
"The offence plays a role in the disruption and prosecution of returning foreign fighters and their associates," he said.
The moves comes as the intelligence committee officially endorsed the attorney-general's listing of Ansar Allah, known as the Houthis, as a terrorist organisation.
The Yemen-based rebels have attacked foreign ships passing through the Red Sea, sparking the US to head an international coalition to counter the attacks.
"It was pretty clear-cut evidence, since 2022, there were some 19 terrorist attacks conducted by Ansar Allah," Mr Khalil said.
The coalition has called for areas of southern Lebanon to be put on the declared list, due to parts of it being controlled by the group Hezbollah.
The laws and listing come against the backdrop of Australia's security agency ASIO raising the terror threat level from "possible" to "probable".
The change on August 5 was the first time the terror threat level had increased since 2014, when it was raised due to the threat of Islamic State.
