Hello and welcome Dave.
The more the merrier from this side of the country!! Sounds like you and your son had a great nights viewing. Like Roger I looked outside and could not force myself to set up. Daylight saving, dont get me started
However, have you checked out
http://www.heavens-above.com/, a great site for shuttle, ISS, and Iridium times and co-ordinates. A -8 Iridium is passing over Bully tonight at 22:10 daylight savings time in the ESE. Should be visable from Perth.
