Dirty sensor, where to get cleaned? - Sydney

Ok, so, I'm not entirely sure this was the right place to put this thread, but it seemed appropriate to me, apologies if it's in the wrong spot!

Basically, my 5D mk1 is filthy.

Where would be the best place to take it in Sydney? Is Canon the best place to take it to? Would I be safe to clean it myself?

I've used a rocketblower, but it's still filthy...

Cheers!
