Who can do conversions?
In Victoria, only service providers with an Alternative Fuel Systems Assessment and Certification Scheme (AFSACS) Agreement with VicRoads in place are approved to undertake gas fuel system conversions. Conversion work undertaken by a provider without a current AFSACS Agreement in place will not considered an acceptable modification by VicRoads. It may also be unacceptable to vehicle insurance providers.
Compliance requirements

The structural integrity of the vehicle and its continued compliance with standards of registration must not be adversely affected by the installation.
LPG conversions
If the vehicle was converted on or after 1 February 1993, an approved AS 1425 LPG compliance plate must be fitted to the vehicle at the time of the conversion. Vehicles fitted with LPG systems are required to have an 'LP Gas' plate attached to the vehicle number plates, including bike rack number plates.
CNG conversions
