Thieves have struck Kyneton Cemetery twice in the past week.
A large generator worth $2000 and new jackhammer were among goods stolen during a shed break-in last Thursday and just when volunteers thought the worst was over, they returned to find gate locks cut and more tools stolen again on Monday.
Cemetery trust chairman Lindsay Hinneberg said the latest break-ins made it five the cemetery had experienced in the past three years.
"The chance of us recovering these items is not good," he said.
"It's disappointing. We are all volunteers here and can't believe what has happened. Now we have to go through the process of changing locks all over again."
On Thursday offenders cut through a wire fence, damaged the shed roller door and busted a side door to gain entry. It appears the thieves also attempted to gain access to the shed roof.
Volunteers noticed a small cut in the fence a week before the incident and repaired the damage but it did little to deter the intruders.
Other items stolen include a brushcutter, pole saw, blower vac, water pressure motor, fuel drums, Stihl chainsaw, lawn edge mower, and keys to the grounds and equipment.
The thieves were even low enough to take a 24-can slab of soft drink.
It appears the offenders attempted to take a small Cox ride-on mower which was found outside the shed. Volunteers suggested the culprits may have been disturbed by a passing car or ran out of room in their load and abandoned it on the lawn.
The same mower was one of the items stolen and replaced during a break-in at the site about 12 months ago.
Mr Hinneberg said the cemetery trust was in the process of upgrading security and seeking state government funding to do so.
Police have interviewed and charged three 18-year-old Kyneton males in the relation to the first burglary and are continuing to investigate the second.
