Immigration Minister Scott Morrison rejects claims the Australian Government delayed its response to distress calls from an asylum seeker boat that sank off Indonesia, leaving many dead or missing.
More than 20 people, including children, drowned and a further 30 are missing after the boat carrying about 80 people broke up off the coast of Java on Friday.
Survivors say they called for help on Thursday, but no one came.
"The Government completely rejects allegations of a 26-hour delay in response to this tragic incident by Australian agencies," Morrison's office said.
One survivor told ABC TV a GPS location was sent to authorities when multiple distress calls were made on Thursday.
