Australian broadcast stations are unlikely to be confused, on air,

Australian broadcasters are like those in North America and --
DAB/DAB+ or LW aside the UK. Medium Wave (520-1710 kHz give or take)
using AM and VHF (88-108 MHz give or take) using FM. Even the few
remaining shortwave broadcasters use AM. Longwave broadcasting, which
was never a thing in the Americas, but that you all still have is also
AM. I think BBC 4 is at 198 kHz?
As for where to start ... you kind of already have. :-)
