Australia has reiterated support for sanctions against Iran amid backlash from the Middle Eastern nation for joining an international effort to protect shipping in the Strait of Hormuz.
Australia will soon send troops, a surveillance plane and a Navy frigate to help guard oil tanker attacks which Tehran denies it is responsible for.
Kamal Dehghani Firouzabadi, the deputy chair of Iran's foreign relations parliamentary committee, has warned Australia is taking a risk by joining the action.
"I don't think there'll be material damage to Australia. The damage will be to the reputation and prestige of Australia," he told the ABC.
He said he was surprised Australia joined the US-led coalition, accusing Washington of making repeated mistakes including pulling out of a nuclear agreement.
Prime Minister Scott Morrison has warned against conflating the two issues, stressing that Australia's involvement in the coalition is purely about protecting shipping movements.
He's been keen to divorce that from Australia's steadfast opposition to Iran getting nuclear weapons.

"We support the sanctions. We maintain the sanctions there, we maintain the sanctions when it comes to North Korea as well," he told Sky News in an interview aired on Wednesday.
"We want to make sure we don't end up in a situation where a country like Iran has nuclear weapons."
The warship will be redirected from an anti-piracy operation in the Middle East, while the Australian troops will be based in the headquarters that are coordinating the US-led maritime security mission.
Mr Dehghani said Australia joining the military effort in the Strait of Hormuz was unnecessary because Iran protects tankers in the region.
"Donald Trump had already stated the US is trying to milk the cow of the Arabian states. They are doing this with Islamophobia. I'm very surprised they are milking the cow of Australia with this strategy," the senior MP said.
