I've been looking quite frequently on the Australian ebay to see the various styles of radio and TV cabinets they made there back in the vacuum tube era. I see a different flavor as compared with American sets. Your radios have radio callsigns instead of frequencies on the dials. Only one American maker (Packard Bell) did that in the USA. Can't do that today, as stations here change callsigns almost every other year.
There's an Australian collector site

25 years ago I took a vacation in Australia, was a great time, and Australia looks to be one of the few places in the world where they actually like Americans...
I have a couple of Aussie radios:
No TV sets, though. Shipping would be very expensive.
And a radio from New Zealand
They all work, and are quite happy with 60Hz. We used to make outlets back in the 1940's that accept Aussie plugs, and I have a few wired up to provide 240VAC (American homes are fed a pair of 120VAC lines, 180 degrees out of phase. In other words, we get 240VAC with a grounded centertap. Small loads are usually run off 120V, and big loads like electric ovens and big air conditioners get 240VAC). Both current carrying prongs are hot with 120VAC to ground, but as all Aussie radios have power transformers, it doesn't matter.
