Hey Mick,
This is a site I used as a reference source on what constitutes a good
pair of binoculars. In general any decent binoculars in Australia were
way overpriced compared to the US. With the strength of the AUS$ at the
moment now is probably a good time to buy from overseas off the
internet. I got my Pentax 10x32 off ebay.
Cheers JAG
