Make sure vehicles are locked and any valuables are removed or placed out of sight.
If you are heading away during the school holidays, ask a trusted neighbour to keep and eye on your property.
You could also ask them to clear your mailbox or, if you are going to be away for an extended period, put your mail on hold or have it redirected.
Consider putting some internal lights on timers.
If you have a burglar alarm, check its back-up batteries and make sure it is working and also check that security lights are working properly.
If your children are old enough to be out and about on their own, know where they are, ask what their plans are and keep in contact with them.
Have a safe and enjoyable school holiday.
