The City of Coffs Harbour covers 1,174 km² with 78.8 km of coastline. Its 33 localities run from Corindi Beach, Red Rock, Arrawarra and Woolgoolga in the north, through Emerald Beach, Moonee Beach, Korora and the city, to Toormina, Sawtell, Boambee and Bonville in the south, and inland to Karangi, Nana Glen, Coramba, Lowanna and Ulong. Council puts the population at more than 78,000 and describes the area as one of the fastest growing in regional NSW. South of the boundary are Bellingen Shire, with Bellingen, Urunga and Dorrigo, and the Nambucca Valley, with Nambucca Heads and Macksville.
State licensing works as described on our Sydney tradies page, and nothing about it changes on the coast. What is local is that the City of Coffs Harbour runs water and sewer itself and also regulates plumbing and drainage. Plumbers and drainers give it at least two days' notice before starting work on a sewer connection or an on-site sewage system, book inspections before anything is covered or backfilled, and within two days of finishing give the owner and council a certificate of compliance, plus a sewer service diagram where sewer work was done. Drinking water comes from the Clarence River catchment and is stored in Karangi and Shannon Creek dams, under a regional scheme that links the Coffs Harbour and Clarence Valley bulk supplies.
The weather is the big local factor. The Bureau of Meteorology's long-term record for Coffs Harbour averages about 1,700 mm of rain a year, with February and March the wettest months. On 23 November 1996 up to 300 mm fell in about two hours, water rose about 1.5 metres in the town centre, around 260 homes and 200 commercial buildings were flooded and one person drowned. Another flash flood followed on 31 March 2009, with more than 300 mm in the hills that afternoon and evening. Then came the October 2021 hailstorm over the southern suburbs, which left a Toormina shopping centre badly damaged alongside hundreds of house roofs.
Salt is the slower problem. BlueScope's guidance for walling is stricter than for roofs: it recommends stainless within 500 metres of breaking surf and COLORBOND Ultra from 500 to 800 metres. A builder, roofer or fencer who knows those distances, and says on the site which products they use near the beach, gives a coastal owner a reason to call. Your supplier will have the current guidance; the website simply states your own practice.
Two other things are changing the area. The bypass, with 21 bridges along its 14 km, is due to open to traffic around the end of 2026, and horticulture has moved beyond bananas, with council describing blueberries as the largest crop. Our team works from Adelaide, so a Coffs project happens over the phone and by email. Send through your licence number, services, towns and some photos of finished work; a draft link comes back for you to go over, and payment waits until you approve it.
