Federal Opposition Leader Peter Dutton raised the prospect of a "catastrophic outcome" as the result of Palestinians receiving visitor visas to come to Australia amid the Israel-Gaza war.

The extraordinary claim follows days of the Coalition hammering Labor about Australia issuing 860 temporary visas to Palestinians.

Federal cabinet minister Ed Husic yesterday took aim at the Coalition's commentary on the issue.

"The conditions of visas will be as those which apply to people who come to Australia from other parts of the world," Senator Wong told the ABC on Wednesday.

Mr Dutton said among the Palestinians receiving visas there could be "one person, or could be 10 people, I don't know" of concern.

Following Mr Dutton's comments, a spokesperson for the government repeated that people must satisfy identity, health, security and character requirements to enter or remain in Australia.
