So I decided to limit myself to the 106 stamps of the "Classic" period
(1849-1900) and to acquired stamps of better quality from that period.
Haunt eBay and don't be afraid to contact the seller and make an offer
on a 'buy it now' listing. I've managed some early mint GB that way.

I also decided to begin to collect Australia after acquiring some 8 000
Australian stamps in a kiloware sale. And I was delighted and still am
in discovering the philately of this country that I visited lengtly in 2
occasions.
You should find a copy of Brusden-White if you are going to study OZ
in detail. They're the Yvert specialised of OZ. You'll also need
access to a 'black light' for the few issues in ordinary and
'phosphor' coated.

Thanks for this quite interesting site.
I noticed there is a chapter on Australia that I will visit in detail
ASAP !
It's only fair, just a few items, though I'm 97% complete as singles.

Happy hunting!
