A former special-forces-soldier-turned-Liberal-MP says allegations Australia's elite soldiers may have committed war crimes in Afghanistan should be taken seriously.
The allegations were raised in a confidential defence inquiry report obtained by Fairfax Media.
The inquiry was told of unsanctioned and illegal application of violence on operations and disregard for human life, Fairfax reported on Friday.
West Australian MP Andrew Hastie, who served three tours in Afghanistan, said he had confidence in the report.
But he declined on ABC radio to comment on specific allegations or the culture within the Special Air Service Regiment, which is based in Perth.
Labor defence spokesman Richard Marles said the opposition will seek a private briefing about the report.
"Our soldiers, particularly our special forces, work in difficult and complex environments," " Mr Marles said.
"It's important that we know, as a country, that they're doing it in a professional and legal way."
He said information in a report of this significance should not be coming to light via leaks to newspapers.
He called for aspects of the report to be made public.
The inquiry was commissioned in 2016 by the then-head of the SAS and compiled by a consultant who interviewed soldiers and other defence personnel.
The Defence Department said it takes allegations seriously and that another investigation by the Inspector General of the Australian Defence Force would make recommendations on how to deal with the claims.
