The KC-30 can carry up to 100 tonnes of fuel. Its dual delivery systems—probe-and-drogue in the wings and boom under the tail—are designed to refuel the RAAF's McDonnell Douglas F/A-18 Hornet and Boeing F/A-18 Super Hornet multi-role fighters, Boeing C-17 Globemaster III heavy airlifters, Boeing E-7 Wedgetail early warning aircraft, or other KC-30s. The tanker is also capable of refuelling future acquisitions including the Lockheed Martin F-35A Lightning II stealth fighter, the Boeing EA-18G Growler electronic warfare aircraft, and the Boeing P-8A Poseidon maritime patrol aircraft. In its transport configuration, the KC-30 can carry 270 passengers or 40 tonnes of cargo. As well as its aircraft, No. 33 Squadron operates a simulator at Amberley.
