After more than 40 years of racing tradition, the Port Augusta & District Greyhound Club (PADGC) will close at the end of the 2018/19 season.
Due to a decline in both local and travelling trainers and greyhounds, PADGC has decided unanimously to not apply for any further racing dates beyond June 30.
The club's final race meeting will be the Port Augusta Cup on June 29.
Greyhound Racing South Australia (GRSA) CEO Matt Corby said there is a mixed feeling of disappointment and relief.
"The club itself came to GRSA to express the view that the issue with attracting sufficient nominations for racing is only going to continue and, on that basis, racing operations were going to become continually unsustainable," Mr Corby said.
"From Greyhound Racing South Australia's perspective, the Port Augusta club has been one of the most efficient and functionable clubs in the state."
Adding to the difficulty in attracting trainers and greyhounds to the local meetings, PADGC also faced issues with the impact of extreme heat through four months of the season.
As a result, PADGC's final decision was a simple one to make.
"The decision was made much easier that nominations for races had dropped off to such an extent that the opportunity for the club to operate in a viable manner would become untenable," Mr Corby explained.
Mr Corby said GRSA and key stakeholders will be working together with PADGC in the coming months to celebrate the club's rich history and success.
PADGC, established in 1978, hosts its race meetings on the grass track at Chinnery Park.
