A new search and rescue operation is underway off Christmas Island after an asylum seeker boat carrying 80 people issued a distress call.
The Australian Maritime Safety Authority (AMSA) on Wednesday received a request for assistance from the vessel at around 12.25pm (AEST).
A P3 Orion aircraft is at the scene about 94 nautical miles off Christmas Island, and ships have been radioed by AMSA and asked to assist.
A merchant ship is on its way and HMAS Bathurst and ACV Triton are expected to arrive later in the day, AMSA confirmed in a statement.
The latest rescue bid comes after four people died when a boat carrying nearly 150 people capsized in rough waters off Christmas Island on Tuesday.
