Anti-jumps racing protesters have held a rally at the iconic Oakbank Easter races in the Adelaide Hills about 30 kilometres from Adelaide.

The Animal Justice Party, Coalition for the Protection of Racehorses (CPR) and Animal Liberation SA supporters have attended the country club's Saturday meet.

The club boasts that its Easter Racing Carnival, which features the $100,000 Von Doussa Steeplechase and the $160,000 Great Eastern Steeplechase, as being "the world's biggest picnic race meeting".

According to a CPR's Facebook post, the group started demonstrating at the meet six years ago.

"Now is the time we must up the anti and make 2016 the year jumps racing is banned in South Australia," the post read.

About 60,000 people are expected to visit the track across two days on Saturday and Monday.

Hurdle jumping is 'unnecessary'

Animal Liberation SA campaign coordinator Molly Salt said crowd numbers at Oakbank had reduced over the years and people who entered horses into hurdle races did not care for them given the potential for injuries.

"The wastage, the carnage," she said.

"It's unnecessary. I think we are in a society now once we know better, we do better."

The South Australian Parliament is currently reviewing the sport.

Melbourne Cup winning jockey Michelle Payne spoke to the media about riding at the course for the first time.

She threw her support behind jumps racing: "I think it is a great spectacle."

"It gives horses another aspect something after horse racing on the flat. Some of these horses obviously wouldn't have a future on the flat races.

"The ones that don't want to do it definitely tell you they don't want to do it."

Last year the club's chairman John Glatz said there was still significant support for jumps racing.

At the time he said an internal petition conducted at the event gathered thousands of signatures from people who wanted the sport to continue.
