I wondered if there shouldn't be a thread for Australian Postmarks. My collection of Australian postal history is limited, but I am happy to share what I have.
For starters here is a Feb 24 1956 Sydney slogan cancel announcing the Melbourne Olympic Games. With US machine cancels with which I am more familiar, we refer to the number 9 as a "service mark". Is there a local term for these numerations of machine cancels?
I'll let Steve sort that out. Suggestion: Just move as a new thread to Australia : Pre-decimal.
My Opinion. (and it is a head cracker) Ideally for Australia, (Lacking Allan's style database) Postmarks should 1. lie in the states and territories for those before federation (eg: West Australian in Western Australia : Stamps, or similar) (NSW in NSW: stamps or similar) 2, After federation in "Pre-decimal" or "Decimal"
Why? These are all exacting disciplines for Australian collectors. For Western Australia, I have a catalogue of rarities and scarcity index (10,000 postmarks)
Victoria, even deeper, I have 2 volumes of Victorian Postmarks of a proposed 5 volume set.
We could lump them all together, but it may lose interest. One day, a new member may come along, that specialises in NSW say, and his input can enhance the thread. (much like Allan came along with British Postmarks)
