To let us know about a change in tenancy, please complete our online change of address form.

Who is responsible for letting GWMWater know about a change in occupant?

Under the Water Act, landlords and tenants have different responsibilities when tenancy changes.

• If you are a landlord, you must let us know when a new tenant moves into the property.
• If you are a tenant, you need to let us know when you move out.

Keeping us informed helps ensure accounts are set up correctly and avoids billing issues.

If you’re unsure what to do, give us a call on 1300 659 961 or find out more about responsibilities of tenants and landlords.
