Although I didn't want to Jonah myself and buy a suitable male display mannequin too early, a casual Google search surprised me. I typed in "second hand" male mannequin Sydney and up popped a mannequin called, so appropriately: "Bluey"! Perfect! And no need to panic about finding a mannequin that can be painted, or working out which paints were stable enough not to react to fabric.
I immediately got on the phone and secured him.
For my international readers, "Bluey" is a typical Aussie nickname for a red-haired man. (Please don't ask why.)
