I read that the England v whiney arsed convicts game in the Pool stage had something like 10,000 tickets available via the lottery/ballot allocation (bearing in mind Twickenham seats 80,000) and that 800,000 applications were received for tickets for that 1 game.
Australia just aren't the force they were and don't have the draw they once had either, although I always enjoying going to any game where Australia play and support the opposition, sadly I'm away for the Barbarians game this weekend though.
