Australia has imposed a six-month ban on Iranian nationals holding tourist visas, citing concerns linked to the ongoing conflict in the Middle East.

The restriction primarily affects individuals with visitor visas who are currently outside Australia. Authorities said the move was taken amid fears that travellers may be unable to return home due to the unstable situation in the region.

Officials also raised concerns that some visitors could seek to remain in Australia if conditions worsen in Iran. The government said the measure is temporary and will be reviewed as the situation develops. The decision has drawn criticism from members of the Iranian diaspora, who argue the policy unfairly targets civilians.

Australian authorities said exemptions may apply in certain cases, including for family reunification or special circumstances. The ban reflects growing caution among governments as tensions in the Middle East continue to escalate.
