"We didn't want to change anything we did, just to get that first place. Because if we had to change something to get it, that wasn't us. We just had fun and fed off each other."
The winning performance comprised two songs, Mikey and Shroomy Sam, he said. "Mikey is about how everybody is so focused on their own idea of success and that going to uni, getting educated, finding a house, finding a job, having a family - all that stuff. But you have to live in the moment and enjoy where you are, because otherwise you regret it."
The second song was based on surfboards being made out of mushrooms.
"It's a more sustainable way of making surfboards and better for the environment. Basically mushrooms are put in a mould with mulch and the fungi eats around it, goes hard and the board is then coated with a bio-resin."
Nicholas said the boys had no idea they would top this year's competition.
"There was just such a high standard of musicians this year. It was just crazy. From the moment we walked in, we could not pick anything, solo and bands. You could not tell who was going to get what."
The three musicians would all take a gap year next year, making music their priority. "We might only get one shot at this, so we have got to make it a good one."
Mollison, 16, said Friday night's performance was one of the first gigs he went into not feeling too nervous. "I was just ready to get on and perform and I think that really helped with the performance and how it all turned out."
He wrote both the songs he performed - People of the Night and One to One.
One to One was about a John Lennon poster he had in his room, while People of the Night was about a homeless man he met in Greerton a few years ago.
"He came and talked to me like we'd met before and it was just a strange, odd interaction. It struck me as very bizarre but very inspirational." It was also the first song he had written.
Mollison said he felt privileged with the award. "Everybody in my category was crazy talented and I felt very fortunate to take out first prize."
