The four band members stood around, tuning their instruments and loosening up before opening the festival at 11am.

After one more quiet moment, the boys launched into action and didn't disappoint the first crowds through the gate.

"We had a lot of friends in the front row but there were so many other people there," lead guitar Marcus Kent said.

For lead singer Stevie Hammer, it was his second gig with the band.

"I was probably more nervous last night for my first gig but with our mates in the front row it was a lot easier for us," he said.

The Triple J Unearthed winners got a good cheer at the end of their 15 minutes before handing over to local act My Echo.

The rest of the day was a chance to rub shoulders with their heroes.

"We saw a lot of bands from side stage and hung out with My Echo and Lurch and Chief," Kent said.

"Parkway Drive are around, so I'll try and get a photo with them."

Outlines are hoping to tour the east coast with fellow GTM alumni Oh Pacific later in the year and will also support UK act Basement.
