Thieves have struck at the Cowra Golf Club for the second time in one week and fifth time in the past two months.
On Wednesday morning staff arrived at the golf club to find sheds containing members' golf karts and golf clubs had been broken into for the second time this week.
Six roller doors to sheds at the club were extensively damaged in the latest attack and three karts belonging to members are missing.
A number of bags containing golf clubs are also missing.
Members store the clubs and karts at the club "at their own risk".
It is unknown if any of the items are insured.
The golf buggies are conservatively estimated to be worth at least $5000 each.
"If the carts are driven into the river you're looking at $15,000 grand in damage there," club member Terry Johns said.
"We could be looking at $30,000 worth of damage from Sunday night through until today.
"It's not hard to pay $1500 for a set of golf clubs.
Mr Johns said the items taken, like a bright orange driver owned by one member "aren't something the thieves are going to be able to hide".
"For want of a better word it's just malicious, it's not for profit, they're not running around selling this stuff for Ice, it's shits and giggle that they're doing the whole thing for."
During a break in on Sunday night the thieves took seven golf carts, one of which is still outstanding.
During Sunday's break in the thieves actually collided head on with a security guard who was arriving to inspect the site but none of those responsible were detained.
On both occasions the thieves have cut their way through a wire fence alongside the sixth hole to gain access to the golf course grounds.
"This is the sought of thing that breaks the back of a small country club," Mr Johns said.
"We rely on the income from the rental of the sheds and people being here."
Fellow member Terry Winwood-Smith said "we can't keeping going on like this, its reached a point where something has to happen".
"It's bleeding us to death bit by bit," Mr Winwood-Smith said.
"It's death by a thousand cuts," Mr Johns added.
The golf club is holding a meeting with members and Cowra police at the club tonight to discuss the break ins.
"We might have to get a dog," Mr Windwood-Smith said.
Anyone with information is asked to contact Cowra Police on 6341 5099 or Crimestoppers 1800 333 000.
