I run a blog displaying checklists amongst many other things relating to soccer cards and stickers - Football Cartophilic Info Exchange.
I have a lot of Australian checklists but I am always looking for more, some I have already featured include:
Davies & Herbert Ltd - Newcastle Famous Footballers
A.W. Allen - English Rugby League & Soccer Players (1925)
Michelides Ltd. - Sports Club Directory
Scanlens - 1963
Scanlens - 1965
Nestlé Milo - Greatest Moments in Sport
Daily Mirror - Hotspur's Australian Soccer School
NSW Building Society - Phillips Soccer League (1977)
Scanlens - Phillips Soccer League (1978)
Futera - Coca Cola Australian National Soccer League
etc.
I also have quite a few complete checklists but I haven't been able to find decent scans to help illustrate the checklists. These include sets like Cann's Bakery (Newcastle KB United FC), J.C. Hutton (West Australia Football Badges)
