Under Australian/NSW legislation not sure which all cabling including telecommunications cabling must be done by a qualified licensed electrician or cabler. Which i think is a load of bull because you could have a Phd in electrical engineering but it would still be illegal for you to lay cables and wire your home. In its not illegal in new zealand where the government actually publishes information to help you to do it. So are they any smarter and qualified than we are? You need to have a very good relationship with your sparkie. If you choose to do the cabling yourself you will void any insurance you have on your property if something is faulty and causes loss life and if your sparkie is not willing to sign off the work and put his name against the cabling work that was done. Keep in mind that the likely hood of any of that is next to zero but has happened e.g. Free Home insulation scheme, some nong steps on cables while in your roof cavity. The issue is about liabilty and peace of mind, my advice is to get your sparkie in, and get him to direct you to where to chase the walls yourself using thin rope and conduit.
He comes in and actually does the cabling and connections. Do as much as you can that he is willing to sign off on.That way the whole job is signed off and the work insured under his policy, it is not considered as illegal when the building inspector looks at the propety when you sell.
And yes I have cabled my own place, as well and connected fixtures, its not that hard to join three wires that are colour coded.
