OK - here is the full schedule
We arrive (Ms B Watson is along for this trip) on 17 Nov and Depart on 23 Nov. I am in MEL for the day on 19 Nov. and am going to the Blue Mountains (yes - B Watson takes two days of Holiday!) for the nights of 19 and 20 Nov.
I will be staying at the Observatory in SYD and Lillenfels for the Blue Mountains trip.
I have a rather full business schedule, but still have some flexibility in moving things around.
