A spike in vehicle burglaries led to Tasmania Police developing a four-part series of educational videos - 'Don't Give Them a Chance' - aimed at engaging the community in crime prevention.

Police statistics show there has been a 68 per cent increase in vehicle burglaries in the state's North, compared to the same time last year.

Acting Northern Commander Natasha Freeman said police were working hard to prevent and investigate crime, but the community's help was also needed.

"Thieves are opportunistic and by taking away the opportunity they can be deterred," she said.

Since late February there has been a spate of thefts from vehicles around Launceston, with offenders taking property such as jewellery, phones, cash and wine.

Acting Commander Freeman said the thieves might try the handle on a car door and if it's locked they may quickly move on to another car.

"Thieves want a quick and easy entry and will usually move on quickly if they find closed windows and locked doors," she said.

"An open window, unlocked door or valuable items left in clear view are too much of a temptation for many offenders to ignore. Don't extend that opportunity."
