An Indonesian official has criticised Tony Abbott as "unethical" for sidestepping allegations the Australian navy paid the crew of a boat carrying 65 migrants to return to Indonesian waters.
Australia's prime minister did not deny the payment claims in a radio interview on Friday.
He said officials were being "incredibly creative" in responding to asylum seekers.
Agus Barnas, spokesman for Indonesia's co-ordinating ministry for political, legal and security affairs, said Abbott's comments could be interpreted as endorsing bribery and might encourage people smuggling.

The boat's captain and five crew members say they were each paid $US5,000 ($A6,450) after being intercepted by an Australian navy ship on May 20.
