People who help Islamic State-linked families return to Australia would face up to 10 years in prison under a coalition proposal, but aid groups are concerned they could be caught up in the laws.
Opposition Leader Angus Taylor said the coalition would introduce legislation in March making it illegal to assist in the repatriation of people who have gone to declared terror hot spots or committed a terrorist offence.
The proposal comes as 34 Australian women and children linked to Islamic State fighters attempt to return to Australia after being held in a Syrian refugee camp since the militant group's defeat.
