"Since early 2006, over 360,000 Xbox 360 consoles have sold in Australia and New Zealand, with over 320,000 sold into the Australian market alone."

So, 360 sold over 21k in Q1, PS3 should be higher, and Wii could be potentially 2-4 times higher (although I expect this ratio didn't happen every week in Q1).
