After undertaking much investigation into buying 100mm binoculars, and what is involved in freighting then into Australia from the US, I have put together a webpage on Big binoculars for Australian buyers.
It provides some information about 100mm binoculars, what is available for under $1000 (Australian) and information for those wishing to purchase 100mm binos from companies in the US (Customs, Duty, Taxes etc. etc.)

I welcome comments and any additions.
