Workers across the Barossa arrived at work on Tuesday morning to find their businesses had been broken into the night before.
Curves at Tanunda had less than $500 from a cash tin and fundraiser collection tins stolen.
An employee arrived about 5.45am and found items across the reception area knocked over.
The doors were jemmied open.
A window by the front door of the Barossa and Light Herald was smashed.
It appeared someone had tried to break a hole, reach their hand in and access a lock to gain entry.
The Barossa Visitor Information Centre and WFI Tanunda were also targeted on Murray Street.
WFI Tanunda’s Dave Rawlinson described the attack as an “inconvenience”.
“We didn’t have anything stolen, it was just more of an inconvenience than anything,” he said.
“They just ripped everything out of the cupboards and threw it all over the floor, nothing was broken, nothing was stolen.”
Thieves also broke into a hairdressing business at Lyndoch by forcing a side door before stealing cash and hair styling products.
Police enquiries are continuing and if anyone has any information that may assist police with these break-ins, they are urged to contact Crime Stoppers on 1800 333 000 or online at crimestopperssa.com.au.
Police remind business owners to ensure that they lock all doors and windows between business hours, improve security of doors and windows where they can and consider installing alarms and CCTV equipment – not only to act as a deterrent but also to assist police in identifying any suspects.
