Police investigations are continuing into what caused the damage, but Driftwood Cafe owner Peter Jacobi said he retrieved two bullet-like projectiles from his building early on Sunday morning.
"Basically someone's decided to have a bit of fun, but we didn't think it was real funny," he said. "
There was a couple of lead projectiles found, one in the door - still jammed in the glass - and the other one we found on the floor after it had bounced off the wall a couple of times.
"It was definitely a lead projectile; it looked like a lead tip that had been smacked up against a wall because it was all flattened out. "
I'm not a scientist or a ballistics expert but I would put it at, if someone asked me, a .22 calibre bullet.
"It had to go through the glass and through a wall so it would want to be a pretty good shanghai to do that."
Mr Jacobi said it was very concerning to think this sort of thing was happening in the small beach-side community; especially given it was the school holidays.
"This is such a safe family community, you just don't think of something like this happening in this area. It's out of the way, it's always quiet and safe," he said.
"A few customers are shocked that something like this could happen.
"If it's someone just out skylarking and having fun, it's a pretty dangerous way to have fun.
"When we were making coffee in the morning we had to go through all the cups to make sure there was no glass because we found glass all over the saucers."
Mr Jacobi said he discovered the damage early Sunday morning and a customer had since told him they heard screeching tyres and what sounded like gunshots at about 11.30pm Saturday night.
He said he'd also been told a car at the nearby caravan park was targeted.
"We heard there was one car over at the caravan park with the back window broken," he said.
"To know that there were tents only a few meters from where the car was shot at is also quite a disturbing fact.
"It was right on the edge of the caravan park, so probably just opportunistic, it was the probably the closest car to the road."
Mr Jacobi said he urged anyone with information to call Bundaberg Police or Crime Stoppers on 1800 333 000.
Bargara police confirmed the incident had been reported and investigations were continuing.
