More bands to be announced. Blink 182 will play with or without Travis. I'd want to see at least 11 of those bands. Great line up so far, but not the full line-up.
There's usually more bands announced but most of the time they're local bands endorsed by Australian radio. Other Bands get announced are bands that AJ (The event organiser and founder) hasn't been able to finalise yet, and a band usually pulls out for one reason or another.
