One of three asylum seekers claiming Australian border protection officers deliberately burned their hands, during a controversial Operation Sovereign Borders turn back, has spoken out about the ordeal.

In January, allegations emerged that officers deliberately burned the hands of asylum seekers on hot engine parts after the Australians boarded the vessel to send it back to Indonesia.

An asylum seeker claims he was deliberately burned.

The Abbott government continues to dismiss these as unsubstantiated claims of inappropriate conduct and says it accepts assurances from Customs and Defence about the conduct of their personnel.

There are clear rules and guidelines to govern behaviour and use of force in relation to the conduct of operations by Border Protection Command, it says.
