Australia's death toll in the latest Bali bombings rose to four after a missing couple's bodies were identified formally by the Indonesian authorities.

Australian Foreign Minister Alexander Downer on Thursday confirmed that the couple, Colin and Fiona Zwolinski, from Australia's southeast city of Newcastle, have been killed in the Bali bombings last Saturday.

"We can now confirm that four Australians have actually been killed in the bombings in Bali," Mr Downer told Australian Broadcasting Corporation radio.

"The bodies of Colin and Fiona Zwolinski have now been identified formally by the police and we're able to verify that it 's them who were killed," he said.

Earlier, a 16-year-old boy from the state of Western Australia and a 48-year-old woman from Newcastle have been confirmed dead in the bombings.
