The NSW rules apply in full: a licence for plumbing, draining or gasfitting work of any value, a contractor licence to contract for it, and Fair Trading's advertising guidance asking for the licensee's name, licence number, category of work and a business phone, websites included. Our Sydney plumbers page covers them. Plumbing, draining and gasfitting are in NSW's automatic mutual recognition scheme, but an interstate licensee has to notify Building Commission NSW before working here and some limits apply, so Queensland plumbers should check the conditions first. Going the other way, our Gold Coast plumbers page sets out the QBCC side for Tweed plumbers who cross into Queensland.
Tweed Shire Council is both the water and sewer authority and the local plumbing regulator. It wants an approval before anyone connects to, disconnects from or alters its sewer, stormwater or water systems, and that includes minor alterations, renovations, additions and moving a drainage line. Approved work then needs the licensee's permit to do plumbing and drainage work, lodged at least two working days ahead. Inspections, booked online or by phone with about a day's notice, come before anything is covered: external and internal drainage including trade waste, water rough-in, stack work, stormwater connections, recycled water plumbing, sealing old services, changes to on-site sewage systems and land application areas, then a final before the building is occupied. A new water connection is a separate application, priced by pipe size, after which council arranges the metered connection. Council looks after the pipes up to the meter and the sewer connection point; past that, it's the owner's.
Council's backflow policy, now in its third version, adopted in September 2025, states that cross connections between drinking water and non-drinking supplies are illegal. Where an owner fails to repair, maintain, replace or test a backflow device, council can have the work repaired, apply penalties, or restrict or disconnect the water connection. On unsewered land, approval to operate an on-site system belongs to the owner rather than the land, so each new owner applies within 60 days, even where the system was approved when it was built. Drinking water is treated mainly at the Bray Park plant near Murwillumbah, with small plants at Uki and Tyalgum, and Clarrie Hall Dam is the shire's main storage; council says that on current growth projections the dam wall needs raising by 2032.
The river shapes the work. In the February 2022 flood the Tweed peaked at 6.5 metres at Murwillumbah, 200 mm above 2017, and at 4.8 metres at Tumbulgum, 800 mm above 2017. Council reported homes and businesses flooded at Tumbulgum, Tweed Heads South, Bogangar and Pottsville, with Uki, Mooball, Burringbar and Crabbes Creek hit harder than in earlier floods. For a time residents were asked to use water only for drinking, food preparation and personal hygiene while the treatment plants came back, with boil water alerts at Uki and South Murwillumbah. By mid-March, more than 2,100 buildings had been found damaged and 498 homes declared uninhabitable.
The shire runs from Tweed Heads, Tweed Heads West, Tweed Heads South, Banora Point and Terranora along the coast through Kingscliff, Casuarina, Bogangar, Cabarita Beach and Hastings Point to Pottsville, and inland to Murwillumbah, Bray Park, Condong, Tumbulgum, Uki, Tyalgum and Burringbar. Byron, Lismore and Kyogle councils border it to the south and west.
