I would like to get a list of the Australian TV channel frequencies and
in particular the Digital channels. Could anyone suggest where I might
find them?

Try these.
List by Channel order.
http://www.acma.gov.au/acmainterwr/_assets/main/lib100059/tv_7.pdf

List by area served.

Digital Channels are highlighted in Blue.

Cheers

I'm intrigued as to why the same channel in different areas are on slightly
different frequencies...

Thanks everyone, just what I wanted!

It's to reduce interference during periods of enhanced propagation.

That's telling him...

Yeah it is but I wonder how much difference fractions of megahertz makes?
I suppose a few dB difference (due to the frequency offset between
interferers) could help somewhat in freak conditions.

Still, the most interesting thing is that you can never assume "Channel 2"
is exactly frequency "X"

There are two reasons.

If there is a digital channel or channels adjacent the frequency
of a lower analogue channel is shifted down to stop the digital
channel interferring with the stereo audio carrier on the analogue
channel.

The other is when there is an overlapping area or possibility of one
during periods when propagation is causing a channel to transmit into
an area where it normally dosn't reach interference can be
minimised by using a GPS locked precision offset on the carrier
frequencies. This offset is most effective at a value of 26 Khz or
multiple
due to the sideband distribution in a normally modulated TV signal.

You have a problem with the accuracy of my reply, or the brevity?

You didn't mention the digital offset.

I didn't need to.
The original question already stated that.
"I'm intrigued as to why the same channel in different areas are on
slightly
different frequencies..."

My response was in that context.
