Riding safely was a focus on Rottnest Island with a record number of visitors heading to the island over the summer holidays.
About 220,000 visitors, over December and January, were urged to wear their helmets as part of the Summer of Safety campaign.
From December 15 to January 30, visitors demonstrating good behaviour received a competition entry form from Rottnest Island Police.
More than 100 entrants have gone into the draw to win a weekend on Rottnest Island, including ferry tickets and accommodation for a family of four.
Winners will be announced on the Rottnest Island website at http://www.rottnestisland.com
