Yes Skytrain, it is the Harry Houdini's Voisin Biplane, bought in England, in their first flight in Australia.
I am not well enough versed to say whether that was the first motorized flight in Australia, first sustained motorized flight there, or just Harry Houdini's first flight in Australia, but the picture says "first flight in Australia". Maybe there is some controversy on the subject, too....
All yours!
