Trade licensing in NSW is handled by Building Commission NSW, the state's building regulator. A contractor licence is needed to do or advertise residential building work valued at more than five thousand dollars (labour and materials, including GST), and specialist work (electrical wiring, plumbing, drainage, gasfitting, and air conditioning and refrigeration) needs one whatever the job is worth. The NSW Government's guidance on building trade advertisements says the licensee's name and licence number must be shown in all advertising, including online, and that a registered business name can be used in place of the licensee's name. Customers can look you up on the government's Verify licence site, which shows the holder's name, licence categories, expiry date and current status.
Under the NSW Government's 2017 district order, Greater Sydney is divided into five planning districts covering 33 council areas: Eastern City, Central City, Western City, North and South. Your customers won't use those names, but the council list is a handy checklist when you decide how far you'll travel. The Western City district alone takes in eight councils, from Hawkesbury and the Blue Mountains down to Wollondilly and Camden.
New suburbs are still being planned on the city's edge. The NSW Government's North West Growth Area includes Riverstone and Schofields, and its South West Growth Area includes Leppington and Oran Park. If you fence, landscape, install air conditioning or fit out new homes in those estates, name those suburbs on your site; a general "Western Sydney" line won't match what a new owner types into Google.
Weather matters for some trades too. The Bureau of Meteorology says large hail is most common in spring and early summer, and it describes Sydney's April 1999 hailstorm as the most destructive in Australian history. If you do roofing, glazing, tree work or storm repairs, the site should say clearly whether you take urgent jobs and which areas you can reach quickly.
On service areas, our advice is simple: give your home base, list the regions you cover with their main suburbs, and say where you don't go. On a one-page site that's a short list beside the quote form; on the 8-page site, your two or three busiest regions can each have a page with jobs you've done there. We're an Adelaide team, so we work with Sydney tradies by phone and email: you send photos and your suburb list, and we send back a draft to check on your phone.
