Hi all - I've just come across what looks like a new Australian astronomy equipment buy/sell site that's trying to get off the ground. Paul (the webmaster, who looks like a keen amateur) has put some effort in as it seems quite functional. While there are lots of specific telescope buy/sell sites around, there are few that cater specifically to the Aussie market.
FYI - I'm not affiliated with his project, I've just mentioned it here for you to peruse if you wish. He did email me at my Omaroo site asking me to have a look at it for him and apologised for the unsolicited email. I have no problems with that type of mail if it comes with a personal apology. I don't know how commercially successful it could be, but congratulations on him attempting it anyway!

Good luck to Paul and his endeavour!
