The "best and biggest sustainability event in Australia" has drawn thousands of people to Eldorado for the third year.
Selling out within hours for its first day, the festival returned to Centennial Park after being pulled one month out in 2020.
Organiser Kate Nottingham said it was great to be back.
"The talk tents have all been packed this year - there has been three and any time I've been past them they've been spilling out with people," she said.
"People are here to really soak up the knowledge.
"They come for the products, the music and the food but the in-depth stuff is what they're really after."
Attendees were eager to hear from the likes of Violet Town's David Arnold, who spoke of strategies to catch and store more water amid the changing climate.
Electric vehicles were an addition this year and enthusiast Paul Baker drew a crowd.
"He led everybody over to the electric vehicle area after that for a Q&A, so people can ask about life with an EV," Ms Nottingham said.
"I've seen a lot of people at interactive workshops - people are loving the leatherwork and all the natural building stuff."
Indigo Power was among the local exhibitors and the Ovens Landcare Network returned for the third year, holding a stall with information about sustainability.
Victorian Landcare facilitator Penny Raleigh was kept busy throughout Saturday.
"This year we've been very, very busy," she said.
"We've been talking to a whole range of people.
"There's lots of locals who have come up - we have guides for revegetation and just general interest.
"We've been talking about just about everything."
Ms Raleigh said there was a strong patronage from locals but people had also traversed states to attend.
"I was talking to someone from Newcastle," she said.
"Two years ago, someone from Brisbane had come down to get to this.
"It's a massive event and it's amazing how many locals do come."
