The festival's first three-day event will place focus on family, fun, local produce and performers.

Tomorrow's opening day will feature Melbourne headline act The Go Set, supported by a host of popular Tasmanian performers.

Festival director Bridget Nicklason-King said she expected the biennial event to  sell out again  after recording a bumper 2012 crowd.

``We've probably got more than 100 musicians, and at least 30 bands, and almost all of them are Tasmanian,'' Ms Nicklason-King said.

``It's very community-focused.  All of our market stalls, all of our food stalls are supplied by local farms. It's all organic where possible.

``We've also had our own festival beer created by Brewnouveau with Seven Sheds just for this.''

Due to the  environmentally sustainable vision, Ms Nicklason-King said attendees were asked to bring their own plates, bowls and cutlery - as well as enough cash to survive the weekend.

``We have a no-rubbish policy, which means that none of the stallholders provide food or drinks on disposable utensils,'' she said.

``It's got better and better each year. We're closer and closer to becoming environmentally sustainable - the entire festival is run on solar power.''

Saturday's program includes a headline performance from former John Butler Trio drummer and Bomba frontman Nicky Bomba, and  Ramornie sister duet Siskin River will headline the following day's program.
