Prime Minister Tony Abbott will interrupt his week in Arnhem Land to farewell troops heading to Iraq.

Prime Minister Tony Abbott will fly out of Arnhem Land on Thursday to farewell troops bound for Iraq.

Hours before touching down in the region last weekend, Mr Abbott announced the deployment of 600 troops to help combat Islamic State.

He had indicated he may cut his week-long trip short to deal with security issues but will instead interrupt the trip to farewell troops.

The prime minister will fly out of Nhulunbuy after attending a World War II commemoration at Yirrkala war memorial.

AAP understands Mr Abbott is considering visiting one of two bases to farewell troops – one being the Amberley RAAF base near Brisbane, where Super Hornet fighter jets are based.

Opposition leader Bill Shorten is also hoping to attend.

“I think it’s important that Australia’s defence men and women recognise that all Australians are supportive of their professionalism and the efforts they make on behalf of Australia,” Mr Shorten said.

The prime minister remains committed to fulfilling his promise to spend a week in indigenous communities so will return to Arnhem Land on Friday.

He has been running the government with the help of several ministers from a temporary tent village in the area.
