Next thing is to decide if you want a "digital" clock or clock with hands.
Flash is also an option... there are several good .swf clocks available also.
For the dual timezones... either get it from the client machine with the local TZ and do the offsets for Oz and UK or you can base it on the server time and do the TZ offset.
