A Royal Australian Air Force plane has delivered ammunition to Kurdish forces in northern Iraq before returning without incident to an airbase in the United Arab Emirates, Defence says.
The C-17A Globemaster aircraft flew to Tirana in Albania over the weekend where it was loaded before delivering the ammunition to the Kurdish town of Irbil via Baghdad.
It then landed back at Al Minhad Air Base in the UAE.
RAAF C130 Hercules aircraft have already been involved in dropping aid to communities in northern Iraq threatened by the advance of Islamic State militants.
The new RAAF role in flying in small arms and ammunition is part of a US-led effort to fend off the IS militants and on Tuesday received the backing of UN chief Ban Ki-moon.
