Tickets for Manchester! HELP PLEASE!!!!

I am going to do the Australian thing and travel in the UK later this year. I have just noticed thast they are going to be playing in Manchester when i am over. Is there a websit that i can get tickets from? And wil they post it here to me in Australia as i would really love to see these guys again. Any help on this subject would be appreciated. I cannot call as the phones i use have some kind of international block (it comes from living with a paranoid dude who has lived with too many backpackers). PLEASE PLEASE help a young Australian man realise his dream of seeing NO on their home soil.
