HMAS Stalwart (III) is the second and final Supply Class Auxiliary Oiler Replenishment (AOR) ship built for the Royal Australian Navy.
The ships are intended to carry fuel, dry cargo, water, food, ammunition, equipment and spare parts to provide operational support for the deployed naval or combat forces operating far from the port on the high seas for longer periods.
In addition to replenishment, the vessels can be used to combat against environmental pollution at sea, provide logistics support for the armed forces, and to support humanitarian and disaster relief (HADR) operations following a natural disaster.
