Not sure about 'atmosphere' but you might have had a ground full of drunken Aussies on working holidays rocking up to it going "bloody hell these Poms are crap mate, look even old man Hodgo's runnin rings around 'em. HEY BRETT! GO THE TIGGGES!! YEAH MAN GO THE TIGGES!"

I went the Oz/Kiwi game at The Stoop, great atmosphere, Kiwi and Oz combined would have created a great foil against the English.

like i said at twickenham the other day the lower tiers were packed out with a fantastic atmosphere, who cares if the aussie/kiwi fans are there more interested in a p-up and being in fancy dress, they'd create some noise and not just booing when sam t gets the ball!
