Happy Australia Day! You could stay at home with a four-pack of Fosters and a Vegemite sandwich, but we'd expect something more imaginative from a Londonista. There's plenty of choice across town, with Aussie wine-tastings and singalongs galore (yes, tonight you do come from a land down under, where women grow and men chunder...or something). But our pick has to be the (Wii-bound) snowboarding competition at the Porchester in Bayswater tonight. For more ideas, here's a handy round-up of events, which stretch throughout the whole week as you'd expect from such a fun-loving nation.
