Up to 120 visiting golfers will descend on the Mount Burr golf course this weekend for the third and final leg of the annual tri-challenge involving the Millicent, Loxton and Blackwood clubs.
The three clubs have competed for the trophy for around three decades with competitions hosted on a rotating basis on the March, June and October long weekends.
Millicent Golf Club president Mark Pilmore said his host club was only a handful of points off the pace after the two opening weekends.
He said the 2021 winner would be determined by the results of play on Saturday and Sunday.
Mr Pilmore said the presence of so many out-of-town golfers was a boost to the Millicent economy.
He said the tri-challenge was founded around 30 years ago by recently-deceased Millicent Golf Club stalwart Graham (“Arch”) Sunderland.
“Our club receives great sponsorship from people like Scott de Bruin, of Mayura Station,” Mr Pilmore said.
“A number of golfers from Adelaide will play our course and then dine at his Tasting Room restaurant.”
