Yes, you can take out a GIO Home and Contents insurance policy for your holiday home, provided that the home has not and will not been unoccupied for more than 60 days at the time you take out the policy (Note: a period of unoccupancy starts when the home or unit becomes unoccupied and comes to an end when you, or someone nominated by you, has occupied the home or unit for at least 2 consecutive nights).
If your home becomes unoccupied during the period of insurance and you have to make a claim under your policy for an insured event, you will need to pay an unoccupied excess. This excess applies in addition to any other excess if at the time of the incident covered by your policy, the home or unit has been unoccupied for more than 60 continuous days.
