Thanks, Malcolm. I'm not too familiar with Australia, but the population density maps suggest that the west coast might have fewer transmitters than the NSW area.
I also read that your television stations will transition to digital over the next couple of years. The U.S. went digital last year, and most stations which had been operating in the lower VHF channels opted for higher frequencies. Here in Arizona, that made it easy for me to monitor Mexican television transmitters (they're still analog) without any local interference.
