Opposition Leader Anthony Albanese wants a peaceful resolution between the US and Iran, saying military conflict is not in the interest of anyone.
Prime Minister Scott Morrison confirmed he discussed with US President Donald Trump on Thursday the nuclear deal at the heart of the Iran dispute.
But Mr Morrison said the talks did not extend into what role Australia could play if the situation deteriorated.
Asked whether Mr Morrison should have flatly ruled out a request for support if there is a conflict with Iran, Mr Albanese encouraged a non-violent outcome.
"We would call upon Iran to act responsibly, but we'd also call upon all the parties to ensure that these issues are resolved in a peaceful manner," Mr Albanese told reporters in Sydney on Saturday.
"A military conflict is not in the interest of anyone in terms of this dispute."
He said it is a matter for the Morrison government whether it should consider sanctions on Iran.
"We have asked for briefings and we will have further briefings next week," he said.
