Home Affairs Minister Peter Dutton is considering listing Hezbollah in Lebanon as a terrorist organisation.
Mr Dutton has indicated he will receive security briefings on the Shiite Muslim political party and militant group before its status is reviewed in April.
"I mean, when you look at the activities of Hezbollah, nobody should have sympathy for the way in which they conduct themselves," he told 2GB radio on Thursday.
"But we need to make decisions based on all of the facts and unfortunately sometimes in these cases, all of the facts aren't publicly available.
"We've got to make a decision speaking to the agencies and working out what sometimes is a line-ball call, but there are other equities that we need to look at in the consideration of many of these matters."
Mr Dutton said he relied heavily on advice from the intelligence agencies ASIS and ASIO, as well as Defence and other government agencies.
The minister indicated there were often a variety of factors at play, including intelligence sharing arrangements and counter-terror cooperation.
The issue has cropped up again after a prosecutor's bid to have a Sydney man declared a "high-risk terrorist offender" failed because the Australian government has not declared Hezbollah a terror group.
The group's external security organisation has been listed as a terrorist organisation in Australia since June 2003.
