Authorities praised the behaviour of crowds and there were no major medical emergencies by Sunday afternoon.

Festival director Frank Venuto said the opening of the gate was delayed to allow the property to dry out and for last minute preparations.

He estimated about 12,000 went to the festival.

"It's similar to last year, so again a good turnout given the weather last week and the uncertainty of the event going ahead," he said.

"It's an excellent result in that regard. There was talk of cancellation all week so it was touch and go until the day."

Despite lengthy queues, Mr Venuto said festival goers took the delay in good spirits when the gate finally opened.

"People were understanding and basically just happy it was going ahead and happy to be here. They've been great."

The festival is now in its 14th year and has grown substantially since it was first held. The weekend's event featured five stages with more than 100 artists including DJs, bands and visual artists.

Gra Hince waited two hours to get into the festival but he said it was worth

the delay. He had previously been to several Rainbow Serpent Festivals.

"We didn't mind waiting because you know what to expect when you get in here," he said.

He believed the festival had changed a lot since he first started coming but it still had a good atmosphere.

"It used to be the hippy crowd. It's just starting to change but it's cool."

Visual artist Stephen Allen supplied a drawing to the festival with "intricate geometric designs".

Sitting in the shade while puffing on a hookah pipe, he said the weather at the festival was better than last year when strong winds caused havoc for his large artworks.

He said this year's event was serene and peaceful.

"It was really just what I needed, last year was very stressful," he said.

Ambulance Victoria acting group manager Nigel Newby said festival goers had been well behaved and there had only been one patient requiring treatment for a fractured ankle.

"It's all gone very smoothly, it's been fantastic," he said.
