The official word from the ACMA is this:

All customer cabling work in the telecommunications, fire, security and data industries must be performed by a registered cabler. This includes all fixed cabling that connects to, or is intended to be connected to the telecommunications network. All data network systems that connect to or may be connected in the future to the telecommunications network are included in this requirement.

In summary, if the cabling is run through a wall, ceiling, floor or crawl space, it must be installed by a registered cabler. This includes the use of pre-terminated cables and 'clip-through' keystone jacks/wallplates.

If you are aware of these regulations, not a registered cabler and decide to install cable regardless, be aware that you are solely responsible for your actions and their consequences. You cannot blame anyone here for providing incorrect or poor advice.

On the spot fines do apply, you'd be very unlucky to get one but better safe then sorry.

For all those with their registration (and those interested) the standards are located at the Communications Alliance website.
