I hear that Hungry Beast aired a short segment on the lack of Asians on Australian TV recently. Lawrence Leung makes a guest appearance too. You can still catch it on iview. Just follow the link here, select episode 10 and fast forward to the 8:00 minute mark.

Nothing we didn't know already.
EDIT: Found the clip on the Hungry Beast site!
