Just stumbled across this article about Green Day possibly going for a tour in Australia. Same as the USA, they want to do both club and arena shows. Original article is here (see if it's a reliable page), but I transcripted the important part of it here:
Billie Joe Armstrong says Green Day is looking at an Australian tour for “February or March” next year.
“We’d like to do some clubs as well as playing in the bigger places,” Billie Joe told the Herald Sun.
“That’s an experience we haven’t had in Australia since the first time we have been there, playing the 300 to 500 seaters. Australian crowds go off - so being in that small a room would be a lot of fun.”
Green Day are set to unleash their first album, titled ¡Uno!, this Friday and will follow that up with two more albums over the coming months - ¡Dos! - Nov 9th, 2012 ¡Tré! - Jan 11th, 2013
EDIT: Nevermind, just found out someone posted in Random News. Sorry.
