Sailing in Five Islands

The Five Islands group sits roughly off the Port Kembla–Wollongong headland on the Illawarra coast. From the water this coast reads as a mix of industrial port frontage, long open beaches and a compact island group that rises out of relatively deep water; the islands are a visual navigation aid and a focus for sheltered reef patches and birdlife rather than an archipelago of sheltered coves. Sailing here is a coastal, nearshore experience – short passages between the islands, the headlands and the harbour entrances, or longer coastal legs north and south along an exposed shoreline with an open Tasman Sea fetch.

For recreational sailors the area suits a broad range of activity: protected day sails and club racing inside Wollongong Harbour and Lake Illawarra; weekend cruising with sheltered nights in the harbour or well-protected coves; and coastal passagemaking along the Illawarra where the Five Islands act as a waypoint and weather reference. Preparation ranges from basic local knowledge and reef-awareness for trailer-sailers and day boats, to careful passage planning and good heavy-weather preparation for keelboats and passagemakers who will operate in open-coast conditions and may need to keep clear of commercial shipping lanes near Port Kembla.

The Illawarra coastline has a concentration of purpose-built facilities at Wollongong and Shellharbour, while more limited commercial and recreational infrastructure sits at Port Kembla and along Lake Illawarra. Wollongong Harbour provides visitor berthing in Belmore Basin and a protected environment for small craft, with slips and hardstand historically present for the local fishing and workboat fleet. Port Kembla is a working industrial port with deep-water berths, shipping channels and a Vessel Traffic Service; it is not a leisure marina, and recreational craft must treat the approach and operating rules with caution and give priority to commercial movements.

Shellharbour and Lake Illawarra provide a different kind of facility mix. Shellharbour Marina caters for visiting yachts and trailer boats and is convenient for provisioning and shore access. Lake Illawarra, reached via the Windang channel and Windang Bridge area, offers a network of boat ramps and sheltered waters popular for trailer-sailers, dinghies and small keelboats; facilities are oriented to day use and fishing rather than long-term bluewater cruising. Fuel, major repairs and haul-out capacity are concentrated in Wollongong and Shellharbour.

Larger, specialist services (heavy rigging, advanced composite repair or deep-draft haul-out) are more limited locally and may require travel to Sydney or other major centres for complex refit work.

The Five Islands and adjacent coastal waters are governed by a combination of NSW marine park and national park protections, port authority operating rules and state boating regulations. The islands themselves are reserved as a nature reserve managed by the NSW National Parks and Wildlife Service; this designation carries restrictions on landing, fires, and activities that disturb wildlife. Boaters should assume that access to islands and some nearshore reef areas is limited or prohibited without prior permission from the park manager, and that nesting seabirds create seasonal access sensitivities.

Port Kembla and its approaches are subject to port authority rules and Harbour Master Directions. The port operates a Vessel Traffic Service (VTS) for information and traffic organisation; commercial shipping movements, pilotage and exclusion zones apply within the port’s jurisdiction. Recreational vessels transiting the approach must keep clear of commercial shipping channels and follow any directions issued by the port authority. Mooring licences and the use of permanent moorings are regulated by Transport for NSW, and unauthorised use of moorings can attract penalties. Time-at-anchor restrictions and specific mooring rules also apply in NSW navigable waters.

Marine parks and aquatic reserve zoning influence anchoring and fishing. While the Five Islands fall under nature reserve protection, broader marine park zoning and state aquatic reserve rules can restrict anchoring, require anchoring only in designated areas to protect seabed habitats, or prohibit taking marine life in sanctuary zones. Inside Lake Illawarra and associated estuarine waterways there are local rules covering boat speeds, wash limits and vessel behaviour to reduce shoreline erosion and conflict with other water users.

Biosecurity rules for hull fouling and the movement of vessels between water bodies are in force in NSW and should be observed when moving between Lake Illawarra, the harbour and open coast waters.

The Illawarra coast around the Five Islands presents hazards typical of an exposed eastern seaboard: open-Tasman swell, short steep seas when wind opposes swell, and strong gusting in coastal troughs and southerly fronts. The islands are approached from deep water but sit close to the shipping lane into Port Kembla; heavy commercial traffic and the possibility of large bulk carriers turning in the approaches are a significant local navigational consideration. Recreational skippers must give commercial vessels a wide berth and be prepared to alter course early to avoid crossing active channels.

Shoals, submerged reefs and variable bottom types occur close to the islands and in nearshore patches. Some reef and rock outcrops give localised breaking seas in moderate swell; these features can produce confused short-period seas in onshore conditions and make anchoring awkward when the wind and swell combine. Sandbars and shallow plates exist in nearshore beaches and estuary entrances — the Lake Illawarra entrance and some minor coastal creeks can shoal seasonally and require local knowledge for safe transit.

Depths inside harbour basins and channels are maintained for navigation but can be affected by dredging cycles; do not assume consistent depths without checking recent notices to mariners.

Wind acceleration around headlands is common. Southerly and south-easterly flows can be funnelled between headlands, producing stronger gusts than open-coast forecasts suggest. Sea breezes in summer often develop from the south-east to east and can strengthen abruptly in the afternoon, creating lively reaching conditions but also a short, choppy sea state close to the windward shore. Conversely, winter southerly and east coast lows bring the most sustained wind and large swell, and can make exposed legs uncomfortable or unsafe for small craft.

Night passages near the port approach increase complexity because of commercial lighting, traffic and limited options for shelter if weather deteriorates quickly.
