An asylum seeker vessel with 105 passengers on board has been intercepted by Australia northwest of Cocos Islands.
The boat was detected on Sunday by an RAAF maritime patrol aircraft and the ACV Triton was sent to the area.
AAP reports the passengers will be transferred to the Cocos (Keeling) Islands for basic health and security checks, before being sent to Christmas Island.
People arriving by boat without a visa after 13 August run the risk of being sent to processing centres on Nauru or Manus Island in Papua New Guinea.
Opposition justice, customs and border protection spokesman Michael Keenan said five boats, carrying more than 300 people, had arrived in Australia in the past 48 hours.
He said the numbers would continue to grow unless a tougher stance on border protection was taken.
