the gas certificate that Factor mentioned isn't concerned with LPG/CNG etc, but that the installation
conforms to the Australian regulations
, which are not the same as US regs. It may well require a complete re-plumbing of the gas system... but as Factor says, this is not impossible.
In general, 110 VAC wiring
will be OK, but outlet boxes and shore power connectors will be different, and of course any appliances
designed for 110 will not work. Most modern electronic devices that have "wall wart" type power supplies will work on either 110 or 240 volts. Most 110 volt powered battery
chargers will not work, although some made by Pro Mariner are switchable to 240.
FWIW, we have retained 110 volt service
on our boat, but do have a 240 volt inverter
to enable use of locally sourced items. Don't use shore power directly, but do have a multi voltage charger
, and on the rare occasions we have access to shore power that keeps the batteries up.
There is always the slight possibility of making an "offshore" sale
to an Aussie who is heading off cruising. Lots of awkwardnesses in this, but it might avoid the GST and some expenses converting systems to meet local regs.
