I don't know whether Australians send each other cards on Australia Day, but I think they should be given the opportunity to find some here. Australia Day falls on the 26th January, probably too close for sales this year, however, I would like to add some to my store through the year.

I wouldn't bust your chops making Australia day cards...it's just not something that we in Oz do on Australia day.......you'd be lucky if one in a million cards got sold.
