Thinking RAAF low level penetrator in overall Foliage Green (like some WWII RAAF combat aircraft), maybe a conventionally armed B-58A but leaning towards a specialist penetrator / interdictor with more powerful alternate engines preferably more economical turbo fans, either afterburning or non afterburning but with super cruise capability. i.e. Sprey, Conway, Olympus (yes and maybe possibly Iroquois). Pave Tac or Pave Spike either pylon or pod mounted, maybe a rotary bomb bay fitted to the semi permanent centre line pod. Pylon mounted Shrikes, HARMs, Standard ARMs, possibly Sidewinder and Phoenix
. In built Wild Weasel kit, jamming pods. Possibly DSTO (fictional) developed Laser Guided missile using Paveway seeker and maybe Standard ARM airframe and motor for stand off attacks against difficult targets.
