I suppose an 80's boombox is like an oversize "transistor"

If you're careful enough, you can modify a 120V parallel plug with a soldering gun, to melt the plastic a little to twist the prongs to angled positions to mate the Aussie style outlet.

I had though of the shortwave bands as a kind of feature list, for owners to brag about "My boombox can get shortwave stations, can yours?".

The plant I worked, in the mid-60's, still used receptacles like that. The Hubbell devices had the lower outlet flipped 180 degrees. I guess they did that so there was no ground up, ground down issue.
You can also use one of those travel kit adaptors, made for Aussie receptacles.
