A further two boats carrying 108 people have been intercepted in Australian waters, bringing the total number of illegal boat arrivals for June to 1781 people.
That is a record number of arrivals in a single month, says coalition immigration spokesman Scott Morrison.
One boat carrying 41 people was picked up northeast of Ashmore Islands in the Timor Sea on Friday evening, and a second carrying 67 passengers was intercepted at Cocos (Keeling) Islands that night.
Passengers from both boats will be processed on Christmas Island.
Parliament failed to agree on a compromise bill on asylum policy this week, despite about 100 people dying in twin boat disasters in the past 10 days.
