The licensing side is the same across NSW: retaining walls, paving, fencing, decks and pergolas are structural landscaping, a NSW contractor licence is needed for residential jobs over the threshold, and the licence details must appear in your advertising, online included. Our Sydney landscapers page covers those rules in detail. What follows is particular to Wollongong and the Illawarra.
Wollongong City Council's tree rules touch most garden makeovers. Council's permission is needed to prune or remove a tree on private land that is more than 5 metres high, has a trunk 30 centimetres or more across at ground level, or, for pruning, has branches more than 10 centimetres in diameter, and dead or dying trees are covered too. The exceptions are species on Council's exempt trees list and work already approved in a development consent. A Tree Permit takes around 28 working days to process and any approved pruning has to be done by a qualified arborist. Trees affected by a proposed house, extension, granny flat, pool or garage go through the development application instead. Each approved removal comes with a condition to replace the tree: the owner plants a native tree on the property, which they can collect from Wollongong Botanic Garden's Greenplan Plant Sales (two trees in low-canopy suburbs such as Corrimal, Dapto and Woonona), or pays Council to plant one on public land. A landscaper who can plant the replacement, or design a garden around a protected tree, is answering a question most clients will have.
The escarpment brings planning controls of its own. Wollongong's development control plan has a chapter on development in the Illawarra Escarpment (Chapter B06) and another on geotechnical assessment of slope instability (Chapter E12). Separately, the Rural Fire Service's 10/50 clearing rules generally don't allow trees to be cleared on slopes steeper than 18 degrees unless a geotechnical engineer's report sets conditions, and pruning there must keep at least 75% of the canopy. On the steeper blocks of the northern suburbs and the foothills, some wall and clearing jobs start with a report rather than a quote, and saying so on your site sets fair expectations.
Sydney Water's Water Wise Guidelines cover the Illawarra: watering before 10am and after 4pm, trigger nozzles on hand-held hoses, and 28 days of watering at any time for newly laid turf and newly planted gardens. Wollongong City Council's area runs from Helensburgh to Windang and Haywards Bay, with Shellharbour and Kiama as separate councils to the south. West Dapto, which the NSW Government calls one of the State's fastest-growing residential areas outside Sydney, is where many new houses are waiting for their first gardens.
We're an Adelaide team and work with Illawarra businesses by phone and email. You send photos and a list of your jobs and suburbs; we send a draft link, and you pay once you approve it. Our NSW outdoor-trade clients, a tree service in Western Sydney and an excavation and structural landscaping business in the Bega Valley, both cover long service areas, much like a crew working the coast from Helensburgh to Kiama.
