Red Wave Radio

On Boxing Day (December 26) in Australia we have a yacht race that
starts in Sydney Harbour, and about 70 yachts race down the East coast
of Australia and finish up in Hobart some days later.

I would like to follow the progress of the yacht by listening in on the
radio skid.
 Can somebody of the frequency and time this skid starts.

My understanding is all yachts are required to report in once every 12
hours.
