I was searching for a good deal on 10x50 binoculars, and found this on Amazon (from Amazon US).
This is the new version (PWV1050), which seems to have some improvements when compared to the first version (131056). I don't know much about binoculars, so won't get into details I don't understand. I'm sure other users might be able to help with other questions, if they want.
I haven't checked all the options, but the price of the Powerview 2 10x50 on Bushnell US website is USD 64.99, which is AUD 83.72 right now.
The first version is on TED's for AUD 109.95 (you can get a $10 discount if you become a ClubTED member).
TED's has a nice guide too.
