James Radford was evacuated over the border with the help of his billionaire boss, Australia’s richest person Gina Rinehart.

He told 9News he used the stairwell of a hotel to take shelter as sirens sounded, before safely crossing the border in an armoured car.

Meanwhile, Brisbane woman MJ told 9News she hasn’t heard from her husband’s Iranian family in two days.

When they were last in contact, the family sent a video from a town west of Tehran.

“I have faith that they’re alive still, I just don’t know what condition they’re in,” she said.

Foreign Minister Penny Wong earlier confirmed around 1200 Australians are seeking support in Israel and 1500 have registered for assistance in Iran.

The number of Australians needing help is expected to climb, however Wong said there is little the government can do right now for those in Iran with the airspace closed.

The department is working to try to assist more Australians and it’s hoped the bus operation out of Israel will be scaled up.

The Australian government’s latest advice for Iran is do not travel.

“If you’re in Iran, you should depart when it’s safe to do so. The Australian government may not be able to assist with your departure,” a message from Smartraveller reads.

The Australian embassy in Iran remains closed.
