G'day Mick. Welcome to the site.
1. Not that I'm aware of but there is a group of us that get together each new moon at Cambroon near Kenilworth. Keep an eye out on the Star Parties and Observing Sessions Forum.
2. If you use the Search>Advanced Search option you will find a number of way to order your search results including from oldest to newest.
3. Cambroon is lovely and dark
