Hi guys,
As Groucho Marx once said "I refuse to join any club that would have me as a member!".
Seriously, the yearbook has separate entries and contact details for both the AGWA and ASWA. You can also get links to websites from the Quasar Publishing page:
http://www.quasarastronomy.com.au/society.htm
YOu will notice the AGWA have close links to the Binocular Telescope and Optical World (astro shop).
Regards
Glenn
