City of Rockingham – Marine Islands, Wetlands & Wandering Cats

The City of Rockingham stretches from sheltered beaches and the Shoalwater Islands Marine Park to a chain of inland lakes and bushland in Rockingham Lakes Regional Park, with Lake Richmond’s rare thrombolites sitting almost in the middle of it all. These same dunes, wetlands and coastal reserves that make the area special are also easy for roaming cats to reach from back fences and balconies, which is why keeping cats safe at home – with secure netting, runs and cat-safe outdoor spaces – matters so much here (S1, S4, S5, S6, S7, S9).

How the rockingham layout shapes cat & wildlife interactions

Rockingham is built around a low coastal plain: sandy beaches and limestone headlands at Cape Peron and Point Peron, the island chain of the Shoalwater Islands Marine Park offshore, and a belt of wetlands and remnant bushland running through Rockingham Lakes Regional Park from the coast back towards Lakes Cooloongup and Walyungup (S5, S6, S23). Suburbs like Rockingham, Shoalwater, Safety Bay, Warnbro and Port Kennedy sit right against these reserves, while Baldivis, Cooloongup and Waikiki back onto bushland and drainage corridors linked to the parklands (S3, S5, S6).

For a roaming cat, this layout makes it easy to move from quiet backyards into sensitive habitat: along foreshore reserves facing the marine park, through laneways and drainage lines between wetlands, and across road verges where turtles and other wildlife already face vehicle strike (S1, S3, S13). Council information and partner resources note that free-roaming cats can kill wildlife and are themselves at higher risk of injury, disease and getting lost, which is why both the City and animal welfare organisations emphasise keeping cats safe at home rather than letting them wander (S1, S10, S11).

Wildlife & habitats most exposed in City of Rockingham

• Shoalwater Islands Marine Park and coastal foreshore – Offshore islands like Penguin Island and Seal Island, and the surrounding waters of Shoalwater Bay, form a marine park that supports colonies of little penguins, Australian sea lions, bottlenose dolphins and seabirds (S7, S8, S10). On the mainland side, coastal reserves and dunes along Shoalwater and Safety Bay connect directly to residential streets, so cats that roam from nearby homes can move into corridors used by shorebirds and other wildlife, which is one of the reasons cat-prohibited conservation areas have been mapped along parts of the coast (S1, S7, S8).
• Rockingham Lakes Regional Park – This regional park is described as a network of environmentally significant coastal, wetland and upland ecosystems across the Rockingham–Becher Plain, linking Cape Peron and Port Kennedy with Lakes Cooloongup and Walyungup and other bushland pockets (S5, S6, S23). Bushwalking tracks at places like Lake Walyungup and Paganoni Swamp pass through heath, woodland and seasonal wetlands that provide habitat for a wide range of birds and small ground-dwelling animals, which can be vulnerable when roaming cats move in from edge suburbs such as Baldivis and Cooloongup (S5, S6, S19).
• Lake Richmond and its thrombolites – Lake Richmond is a 40-hectare freshwater lake near the coast, notable for a critically endangered thrombolite community covering more than three hectares, viewed from a boardwalk on the eastern shore (S4, S5, S16, S20). National conservation advice and heritage listings describe the thrombolite and sedgeland ecological communities at Lake Richmond as rare and highly threatened, alongside habitat for waterbirds (S2, S9, S12, S24). Keeping cats from roaming into the lake’s vegetated margins and neighbouring reserves reduces additional pressure on birds and small fauna using this sensitive site.
• Suburban wetlands and turtle habitat – Many of the City’s wetlands are home to populations of the south-western snake-necked turtle (Chelodina oblonga), which are already under threat from predators such as foxes and ravens, vehicle strikes on roads and a lack of suitable nesting habitat (S3, S12, S21). Council material and conservation partners note that these turtles use seasonal wetlands and drainage lines; roaming cats that follow the same wet, vegetated corridors can add to the risks facing hatchlings and other small reptiles along wetland edges (S3, S12, S21).
• Beaches, dunes and coastal shrubland from Rockingham to Secret Harbour – The beaches and dune systems running south from Rockingham foreshore through Safety Bay, Warnbro, Port Kennedy and Secret Harbour are promoted as places to walk, watch birds and enjoy coastal scenery (S6, S18, S19). Low coastal vegetation, tidal flats and roosting areas used by shorebirds and other wildlife are easily reached from nearby homes; cats that roam across these open spaces can disturb or prey on animals using the dunes and foreshore.

Common cat lifestyles in City of Rockingham

• Foreshore and balcony roamers – In older coastal streets of Rockingham, Shoalwater, Safety Bay and Warnbro, some cats move between beachside yards, balconies and foreshore reserves, with easy access to dunes and coastal shrubland (S1, S6, S7). Without cat-safe netting or secure runs, these cats can quickly cross roads and wander into areas used by shorebirds and marine-park-adjacent wildlife.
• Wetland-edge backyard explorers – Around suburbs like Cooloongup, Waikiki and parts of Rockingham and Hillman, back fences can back onto wetlands, drainage corridors or bushland pockets linked to Rockingham Lakes Regional Park (S3, S5, S6). Cats allowed to free-roam in these areas may follow drains and tracks, intersecting with turtle nesting routes and habitat used by frogs and small birds.
• Semi-rural and new-estate wanderers – In Baldivis, Karnup, Golden Bay and Secret Harbour, larger blocks, new estates and patches of remaining bushland mean outdoor cats may range across construction edges, horse paddocks, road verges and remnant vegetation (S5, S6, S19). These roaming patterns bring them into contact with wildlife using the last strips of habitat between suburb and regional park.

Cat rules that apply across City of Rockingham

Under the WA Cat Act 2011, all cats over six months of age must be microchipped, sterilised and registered with the relevant local government, and penalties can apply for failing to comply (S1, S2). The City of Rockingham’s cats information page repeats these requirements and notes that registrations run from 1 November to 31 October, with one-year, three-year and lifetime options and pensioner concessions (S1).

Locally, the City of Rockingham Cats Local Law 2018 limits most properties to keeping two cats, with exemptions for veterinary facilities and cases where an application to keep more cats is approved (S1). A 2024 Cat Amendment Local Law introduced mapped “cat prohibited areas” in parts of the City, making it an offence for a cat to be found in those specified conservation areas and allowing penalties of up to $200, with intermittent trapping programs used to remove cats from those locations (S1). The City’s material also states that there are currently no general cat confinement laws across the whole City, even though containment is strongly encouraged for welfare and wildlife reasons (S1).

The Cat Safety Network strongly recommends keeping cats contained at all times – indoors and in well-designed, cat safe outdoor spaces – even where only basic registration is legally required. This guidance sits alongside, but is separate from, the formal requirements set out in the Cat Act 2011 and the City of Rockingham’s local laws (S1, S2, S10, S11).

Suburbs within City of Rockingham

Each suburb in the City of Rockingham will have its own Cat Safety Network page, exploring how cat safety, local habitat and council rules come together at street level. Below is a quick snapshot of how roaming cats and wildlife can intersect across the City’s suburbs, based on council and park information (S1, S3, S5, S6).

• Baldivis – New estates and semi-rural lots close to bushland and regional park corridors mean roaming cats can move quickly between backyard sheds and patches of native vegetation (S5, S6, S19).
• Cooloongup – Older streets and reserves sit near parts of Rockingham Lakes Regional Park and local wetlands, so cats that roam can reach turtle and waterbird habitat via drains and pathways (S3, S5, S6).
• East Rockingham – Industrial and coastal fringe areas with pockets of bushland and coastal reserves where roaming cats may overlap with shorebirds and other wildlife using remaining habitat patches (S5, S6, S18).
• Golden Bay – Coastal housing facing dunes and beaches, with nearby bushland, gives outdoor cats a direct line from cul-de-sacs to foredunes and coastal shrubland (S6, S18, S19).
• Hillman – Leafy residential areas close to parks and drainage lines leading towards wetlands and bushland, creating quiet movement corridors for both cats and wildlife (S3, S5, S6).
• Karnup – Larger blocks and peri-urban edges where roaming cats may range across paddocks, remnant bushland and roadside habitat used by small mammals and reptiles (S5, S6, S19).
• Peron – Suburbs around Cape Peron sit next to coastal reserves and Rockingham Lakes Regional Park, with paths that lead straight into sensitive coastal and upland ecosystems (S5, S6, S23).
• Port Kennedy – Housing adjoining coastal reserves and parts of the regional park places roaming cats close to dunes, wetlands and conservation areas used by birds and other wildlife (S5, S6, S23).
• Rockingham – The town centre and foreshore precinct back onto beaches and coastal parks, so free-roaming cats can wander from courtyards and balconies into busy public open space and foreshore habitat (S1, S6, S18).
• Safety Bay – Bayside homes open onto reserves and paths around the bay where people walk and watch marine-park wildlife, and where cats can intersect with birds using the shoreline (S6, S7, S10).
• Secret Harbour – Coastal estates built around dunes, golf course and reserves mean cats that roam can cross fairways and dune systems that still support native plants and animals (S5, S6, S19).
• Shoalwater – Streets facing the Shoalwater Islands Marine Park foreshore sit directly opposite islands that support penguins, sea lions and seabirds, with mainland reserves that form a buffer where cats should not roam (S7, S8, S10, S18).
• Waikiki – Suburban blocks threaded with parks, drains and walking paths link to nearby wetlands and coastal reserves, creating pathways that roaming cats and wildlife can share (S3, S5, S6).
• Warnbro – Residential areas along Warnbro Sound lie close to beaches, dunes and reserves used for walking and wildlife watching, and outdoor cats can easily range from fences to the foreshore (S6, S18, S19).

A better life for cats in City of Rockingham

• Use netting and secure runs to give your cat safe outdoor time at home – cat-safe fencing and balcony netting or an escape-proof cat enclosure can offer sunshine and fresh air without exposing wildlife or your cat to the risks of roaming (S1, S10, S11).
• Focus on cat safety at home by “cat safing” yards and balconies: block common escape routes, attach netting above existing fences and add climbing shelves and platforms inside the secure area so your cat chooses to stay within the cat safe zone (S1, S10, S11).
• Bring cats indoors, or into their enclosure, at key wildlife times – particularly at dusk and dawn, when many birds and small animals are most active and when road strike risk is higher for roaming cats (S1, S10).
• Enrich your cat’s indoor life with climbing spaces, scratching posts, hiding boxes, window perches and daily play sessions so they burn energy and feel less urge to roam beyond the property (S1, S11).
• Work with local vets and welfare organisations to keep cats desexed, microchipped and registered; this reduces unplanned litters and helps ensure cats that do escape can be returned home quickly (S1, S2, S10, S11).
• If you live near wetlands, lakes or coastal reserves, treat your yard as part of the buffer that keeps fragile habitats and species – including turtles, waterbirds and thrombolite communities – safe from the extra pressure that roaming cats can bring (S3, S4, S5, S6, S9, S12).
