The review will conclude at the end of next month and Mr Abbott’s is understood to have left the door open to a judicial ­review following criticism that the current review is too narrow, a report in today’s News Corporation Sunday newspapers says.

The joint NSW-federal ­inquiry will examine the arrival of Martin Place siege gunman Man Monis, an Iranian, in Australia and subsequent granting of asylum, permanent residency, citizenship, and welfare payments to him.

The Australian Security Intelligence Organisation is also understood to have checked a website of Monis after an anonymous phone call only last weekend just drawing attention to it, the report says.

REPORT: National hotline tipped off to check gunman

The call was to a national security hotline that receives thousands of calls every year and many are hoax calls, it says.

Monis, who had 14,000 “likes’’ on Facebook from supporters, had several websites, a Facebook account and a Twitter account in support of Islam and jihadism but there was no mention of a planned terrorist attack.

ASIO, which is the nation’s domestic spy agency, was aware of a call but the caller did not suggest that Monis had a gun or that he was planning a terrorist act.

ASIO is understood to have looked at Monis’ website as result of the phone call. The hotline receives thousands of calls every year and a substantial proportion are hoax calls.
