Caravan bay charges

Business water use and service charges apply to Caravan parks. Caravan parks can declare some bays as strata-titled or long-term bays (LTB) if they are used for residential purposes for longer than 12 months. These bays are then charged at a different rate.

Water use charges

Water use is billed on a 2 monthly basis. You can find your water use charges on the back of your bill.

Generally, business water use charges apply to Caravan parks. If a caravan park has strata titled or LTB, 150 kL per LTB will be charged at the lowest household water use tier. Water used more than this amount is then charged at the business water use rate.
