AU Regulations on LAN Cabling?

An anonymous reader asks: "After getting a ridiculous quote for the cost of rewiring an office, I started investigating the possibility of doing all the phone/data cabling myself. About 40 RJ-45 ports all coming back to a central patch panel that would be patched into the phone or data switch as needed. My research found that doing this simple job would be illegal in Australia, according to the Australian Communications Authority's (ACA) website. According to them, they have the right to walk in at any time and demand an audit of your LAN, and if it was not installed by a registered cabler, you can be fined up to $13,000. My question is, how does this compare to legislation in other parts of the world? Also, has anyone in Australia ever been subject to one of these 'cabling audits'? Was it painful?"
