Caravan parks are generally billed at the commercial rate. Long-term residential caravan park bays and strata titled bays are charged at different rates. Caravan parks are able to declare bays as long term bays (LTB) to be charged at the residential rate provided they are used for residential purposes.

Water use charges

Water use is billed on a two-monthly basis. You can find the amount of water used as well as the meter reading details on the second page of your bill under meter reading details.

Caravan parks are generally billed for their water use at a commercial rate. If a caravan park has declared long term bays, 150 kL per LTB will be charged at the lowest residential water use tier. Water used in excess of this amount is then charged at the higher commercial pricing tier.
