The discovery came just days after the Bathurst 1000 on Mount Panorama where spectator numbers were limited to just 4000 each day as part of a COVID-safe plan to allow the event to go ahead.

Health authorities called on anyone who attended the Bathurst 1000 to get tested as soon as possible, as well as Bathurst residents with any symptoms that could signal COVID-19.

No COVID-19 cases were detected as a result of the health alert, but more than 350 people got tested the day after the alert went public.

"The sample comprises wastewater from over the past weekend and could indicate a current or previous infection in someone who attended or worked at the Bathurst 1000 motor race, a visitor to Bathurst, or even a local resident," the statement from NSW Health said.

AN international race car driver snapped up a $1.6 million property on Mount Panorama's Conrod Straight three months after it went on the market.

Raine and Horne Bathurst director Grant Maskill-Dowton finalised the sale of the 17-acre property at 489 Conrod Straight, which hit the market after being held by the same family for nearly a century.

An Australian driver who now lives in the United States purchased the property, with negotiations occurring after the property failed to sell at auction.

"I believe they will do some renovations and modifications up there and create it basically as their Australian residence," Mr Maskill-Dowton said.

"I think he'll have family stay there. He is originally from Australia, so he will have family and that reside there as well."

It was understood that the driver has no intention of developing the property for anything other than residential purposes.

The Bathurst 1000 started 30 minutes earlier in an effort to minimise the impact of rain and storms forecast for the region.

According to Supercars.com, the move was designed to cover off the chance of a longer than usual race, should wet weather bring additional safety cars or even red flags.

In front of a near-4000 strong crowd, Shane van Gisbergen and Garth Tander secured the 2020 Bathurst 1000 for the Red Bull Holden Racing Team.

It was Van Gisbergen's maiden Bathurst 1000 title and Tander's fourth.

"It's awesome. The last few laps were really tough with the safety cars but the team did a fantastic job. The car got better all weekend. It's a great way to send out Holden. Garth did an excellent job," Van Gisbergen said.

Cameron Waters and Will Davison finished second.

Organisers began installing temporary seating along Pit Straight to accommodate the 4000 fans allowed on-track for each day of the Bathurst 1000 on October 9.

Images from the Mount Panorama circuit showed hundreds of plastic chairs set up along the hill beside Pit Straight in groups of between two and six seats.

One race fan who contacted the Western Advocate said he was shocked when he saw the seating along Pit Straight on Friday.

Kelso man Graham Scott had bought three four-day tickets for next weekend's race but said he would not have bothered if he knew the seating arrangements.

"Prior to sitting in the stand last year, we always sat on the top of the elevated grass area and would never consider utilising the area close to the track as visibility of the cars on Pit Straight is basically impossible unless you are standing," Mr Scott said.

"I now find that I am paying ... for the privilege of using a hard, uncomfortable plastic chair - or, in other cases, those flimsy fold-up chairs that break without much warning - for four days on the grass in an area with limited view of the track in front of me."

Bathurst siblings Alycia and Jaiden Cogdell found an "ultra rare" furry Thor Ooshie after their mum had done the weekly shopping.

The Ooshie was selling for upwards of $1000 on eBay.

"When [Woolworths first] offered them to us I said 'no', I thought they would all just end up as junk under the bed," mother Sharyn Cogdell said.

As for what they will do with any profits, Jaiden said he wasn't sure but Alicia had a clear idea.

"I'd like to donate the money to the Smith Foundation who help people who need an education and can't access one," she said.
