POLICE have vowed to increase their presence on North Stradbroke Island's roads and beaches to stop motorists taking risks behind the wheel.
It comes after three drivers, including two locals, were caught travelling more than 25km/h over the limit on Main Beach last week.
The motorists were detected travelling at 88, 89 and 90km/h in a 60km/h zone within 30 minutes of each other.
One of the drivers booked had been caught about three days earlier at another location doing 89km/h in a 70km/h zone.
Dunwich Police Station Officer in Charge Darren Scanlan said a driver was also caught more than two times over the blood alcohol limit on Main Beach about 1pm last Saturday.
Police pulled over 20 drivers on the weekend and 17 returned a blood alcohol reading, although all came in below the legal limit.
Sergeant Scanlan said there was a lack of care on the island and people getting caught twice in one week typified the issue.
"Motorists should obey the speed limits, they are there for a reason," Sergeant Scanlan said.
"If is for the safety of all road users and pedestrians, especially on the beaches.
"Here we also get quite a few kangaroo strikes every week. That is why the speeds are what they are."
The maximum speed limit on North Stradbroke Island is 80km/h.
Sergeant Scanlan said the high speeds that police had seen were of great concern.
"Some of the locals think it is the tourists that are speeding, but that is not the case," he said. "It is a mixture of both.
"People coming on holidays, they get onto the beach and are in holiday mode.
"They start cruising because they want to get their campsites, set up and start relaxing so they push the envelope a bit.
"It is all about having a highly visible presence on the roads so we are there to be seen.
"It is not our aim to get people, it is to make them aware."
Sergeant Scanlan said people appeared to be more likely to take risks on the island, particularly if they were camping on the beach.
Police planned to increase their presence to weed out speeding and drink driving.
