Here is a fun card that celebrates Australia and/or Australia Day. Colour it in and fold in half. It is best printed with your printer's borderless settings.
Just for fun, here's a colouring page for the sports chant - Aussie Aussie Aussie - Oi! Oi! Oi! Colour it in Australian flag colours, or perhaps a sporting green and gold...
Why not colour in a card to welcome in Chinese New Year, the Year of the Rat? It would make a fun writing activity too, and whoever gets the finished card will appreciate the effort that has gone into it more than a "bought" card!
