Patonga has no natural gas reticulation. Every gas appliance in the village runs on LPG from
cylinder installations on the property. Standard setups use a 45kg cylinder for single
appliance connections, or twin 90kg cylinders with an automatic changeover regulator for
properties with multiple gas appliances — hot water, cooktop, and heater. A licensed gas
fitter must install, connect, and certify all gas work.
45kg single cylinder standard for 1 appliance (hot water or cooktop)
Most common
Twin 90kg with auto-changeover hot water + cooktop + heater
Multi-appliance
Copper gas line from cylinder to appliances
Licensed work only
Compliance certificate required for all gas fitting work in NSW
Mandatory
Salt air from Brisk Bay and the Hawkesbury River estuary attacks copper gas lines, brass
fittings, and LPG regulators. Patonga properties with gas installations more than 10 years old
should have the entire system inspected — corroded fittings are an invisible hazard in
weekender homes that sit unoccupied for extended periods between visits.
Regulator corrosion Brisk Bay salt air attacks pressure regulators

Patonga's remote location at the tip of the peninsula means a gas emergency takes longer to
respond to than in a suburban setting. The combination of unoccupied weekender
properties, coastal corrosion, and remote location makes gas safety particularly
important here. Annual inspection of LPG installations is best practice for any
Patonga property. When selling or leasing, a compliance certificate is a legal requirement.
