After a summer tourist season marred by smoke, threats of bushfires and the cancellation of the Cold Chisel performance, the arrival of more than ten-thousand people will be a welcome change of pace for the area.

Michael Newton, a promoter with a Day on the Green and Roundhouse Entertainment, said 11,000 people will attend the concert on Wednesday and spend hundreds of dollars in nearby towns.

"We already know it will [provide an economic boost]," Mr Newton said.

"From the research we've done and the numbers councils have provided, we know that the spend per head outside the concert in the region equates to $250-per-head.

"That's what is spent on accommodation, restaurants, bars, food, and whatever else people do while they're there."

At $250-per-head and 11,000 attendees, more than $2.75 million could be injected into the region's economy.

Mr Newton said most people attending the concert from outside the immediate region spend two-nights in the area, buying food, petrol and exploring shops.

"All accommodation is booked out, which is a real bonus midweek," he said.

Mr Newton said shuttle and buses to and from the concert were nearly sold out in anticipation of the event.

"It's easily the biggest show at the venue," he said.

"There are 40 Elton shows in this Australia and NZ tour and this is number 25, so he's well and truly in the zone.

"I think it will be, no, I know it will be the greatest show ever in the region.

"It's nothing short of spectacular."

Mr Newton said after a summer of worries, the concert was a chance for people to leave their worries at home and enjoy themselves.

"Everyone been through pretty ordinary time this summer, as a nation we have really," he said. "We had to cancel Cold Chisel there which was really disappointing but now we've got the opportunity to come together on Wednesday night to have a really good time."

A Day on the Green organisers have warned ticket-holders to expect delays on the roads near All Saints Estate on Wednesday, as thousands flock to see the Rocket Man himself in concert.

"Obviously it's a winery, there are only a couple of roads in and out so there will be some delays," Mr Newton said.

"But I think seeing the Elton John show will be well worth the wait."

Gates open at All Saints Estate, Wahgunyah, from 4pm, with Tate Sheridan performing from 5pm.

Elton John will take to the stage at 7pm with the show set to finish about 9.40pm.
