IPSWICH police are warning residents to be aware that thieves will be on the prowl during the Christmas-New Year break.
Crime Prevention Unit Sergeant Nadine Webster said opportunistic sneak breaks - where thieves entered through an open window or door, often while the residents were home - made up most of the offences committed at this time of year.
Sgt Webster said the good news was that people could take a few easy steps to help protect themselves against this type of crime.
"We often see at this time of year that we have offences being committed because offenders are entering through doors and windows that have been left open because of the heat," Sgt Webster said.
"We even see air-conditioners sitting in windows where the window isn't able to be fully shut.
"If the opening is big enough for someone to get their head through, they will likely be able to get the rest of their body through as well."
Police encourage residents to have security screens fitted.
"Sliding windows can also be kept secure on a budget by wedging a length of timber, or dowel, into the track to prevent it from being opened."
