Transporting a big batch of items from England to Australia.

At some point next year I will be wanting to bring a ton of my stuff from England to Australia, it will be 100s of cds and dvds. 100s of console and pc games. My old xbox, my Wii, a few books and other things.

Has anyone got any experience in transporting a batch of items this far a journey, know how long it would take? How much it would cost? How its transported etc?.

I’m clueless!
