Captain Wales, as he is known in the British Army, is on a month-long attachment with his Australian Army counterparts ahead of retiring from the forces.
He spent the first fortnight in Australia's remote north and west, getting airborne in an Armed Reconnaissance Helicopter Tiger.
The prince has flown Apache helicopters for Britain.
"Captain Wales undertook flight simulation training, before heading out with members of the 1st Aviation Regiment on an ARH Tiger reconnaissance flight from Robertson Barracks, Darwin," the Australian Defence Force said.

Hundreds of well-wishers turned out to see the 30-year-old when he arrived in Canberra on April 6 at the National War Memorial -- his only public appearance -- before reporting for duty at Duntroon Military College.
He delivered a letter to the Australian Defence Force head, Air Chief Marshal Mark Binskin, from Queen Elizabeth II, in which she wrote her grandson would "benefit greatly from spending time with the Australian diggers".
In an update, the defence force said Captain Wales met elders and children at the Wuggubun indigenous community in Kununurra, around 470 kilometres (290 miles) southwest of Darwin.
Building on his interest in veterans affairs, the prince also joined some of the army's wounded, injured and ill members to play wheelchair Australian Football League.
