Have a read of the following:
Steering wheels are designed to minimise injury to the driver during a vehicle accident.
When replacing a steering wheel make sure that the new steering wheel complies with Australian Design Rule (ADR) requirements.
Replacement steering wheels must not be less than 330 mm in diameter. If the original steering wheel was designed with a recessed or padded hub, the replacement wheel must be of similar design.
A non-standard aftermarket steering wheel may be fitted to passenger cars and derivatives manufactured prior to 1971. When selecting a replacement steering wheel ensure that it is firmly padded and is constructed so that it will bend on impact without splintering or cracking, and that no parts of the wheel are loose or cracked.
Passenger vehicles built after 1970 are required to comply with ADR 10. The replacement steering wheel must have the appropriate markings indicating that it complies with ADR 10. There are a number of steering wheels certified to ADR 10, so before purchasing an aftermarket steering wheel contact Vehicle Standards to ensure that it is acceptable.
Passenger vehicles manufactured after June 1995, which are required to comply with ADR 69 (full frontal impact occupant protection), they may only be fitted with steering wheels certified by the vehicle manufacturer as suitable for that vehicle.
For example, if your vehicle has an air bag steering wheel as standard, the replacement must be the same. Fitting an aftermarket steering wheel to a vehicle that has an airbag in the original steering wheel is not acceptable.
