The Whadjuk Noongar are the Traditional Owners of Rottnest Island (Wadjemup). As such, the name of this 45 kilometre trail network takes in both cultural and environmental significant landmarks reflects this heritage. The word "Bidi" in Noongar means "trail" or "track".

The Island

Rottnest Island is Western Australia's very own Island getaway, featuring a casual atmosphere, picturesque scenery and some of the world's finest beaches and bays, is located just 19 kilometres off the coast of Fremantle.

It’s a special place for Western Australians and a popular destination for interstate and international visitors. Mediterranean-style climate and indigenous flora and fauna of this Island provide the backdrop to a special holiday experience.


As an A Class Nature Reserve, Rottnest Island preserves and protects its natural beauty; spectacular flora, abundant marine life and wildlife and many unique species.

Rottnest Island's famous marsupial, the Quokka, can be seen around the Island particularly in the mid to late afternoon. During the autumn and winter months (March to August) young joeys may be seen peaking from their mothers' pouch and come spring (September to November), bravely hopping around exploring their new world.

See the osprey nests known to be over 70 years old at West End - Fish Hook Bay. Osprey’s mate for life and return to their nests, adding more to the stacks every year. This majestic raptor has a 1.5 meter wing span. Its scientific name Pandion cristatus, is derived from Pandion, a mythical king of Athens.

Around 35,000 migrating Humpback and Southern Right whales linger in the calm waters around the Island. In April each year they head north to feeding grounds while on their return trip during September to December, the whales and their newborn calf’s spend much of their time playing in the protected Rottnest waters gaining strength and learning all that young whale needs to know before returning to the colder southern waters. You can often see them from the Island itself, with the West End platform providing a prime viewing location.

The New Cathedral Rocks viewing platform allows you to get closer to the resident New Zealand Fur Seals colony without disturbing them whilst they flip and play together in the bay and enjoy basking on the rocks.

Salt lakes occupy ten per cent of the area of Rottnest Island. Many of them - including Lake Baghdad, Lake Vincent, Herschel Lake, Garden Lake, Government House Lake and Serpentine Lake - are permanent and have surrounding beaches. Other lakes such as Pink Lake, Lake Sirius, Lake Negri and the twin Pearse Lakes may dry out in summer. The Gabbi Karniny Bidi explores the unique salt lakes.

The White-striped Freetail bat flying over the Settlement at night – recently discovered as the second mammal species living on the Island.  Rottnest also has 3 species of frogs - the moaning frog (Burrowing frog), the motorbike frog (Western Green Tree frog) and squelching frog (Sandplain froglet). The Tree frog is quite restricted in its distribution, whilst the moaning frog and the froglet are usually associated with low-lying areas, freshwater swamps and seeps.

Protected by several marine sanctuary zones, Rottnest Island is home to 135 species of tropical fish as compared to the eleven species recorded off the metropolitan coastline. The tropical current often brings visitors to our waters such as the Green turtle. Watch for stingrays which often cruise the shallows of Thomson Bay.

You may also spot a pod of Bottlenose Dolphins feeding & surfing in Salmon Bay.


Prior to separation from the mainland, Rottnest Island would have had the same range of plants found today on the adjacent mainland, where around 1,500 native species flourish. It is believed that Rottnest Island was separated from the mainland approximately 7,000 years ago.

The sea-level rose, cutting the island off from the land mass. Exposure to salt and wind eliminated hundreds of species at that time so that today there are only about 140 indigenous species left on the Island. However, fossil remains show that tuart, marri, jarrah, banksia and she-oaks once grew there. The native plants that remain are well adapted to the predominantly nutrient poor soils, along with the salty and often windy conditions.

The vegetation of Rottnest Island is dominated by the prickle lily (Acanthocarpus preissii) and feather speargrass (Austrostipa flavescens) heath community, which occurs in areas previously dominated by woodland. Over 60% of the Island is covered by this heath assemblage, with the summer-scented wattle (Acacia rostellifera) forming a closed scrub in association with the heath.

The woodland community on Rottnest comprises Rottnest Island Pine (Callitris preissii) and Rottnest Island Tea Tree (Melaleuca lanceolata). Prior to European settlement in 1831, over half of Rottnest Island was covered in large areas of woodland. European settlers quickly changed the landscape of Rottnest. Land was cleared and tracks made. Firewood was gathered, especially for the salt works, and the Island was repeatedly burned. Aboriginal prisoners often used fires as an aid in hunting quokkas. At present, approximately 4% of the Island is covered by scattered relic stands of woodland.

Along the coastline plants such as beach spinifex (Spinifex longifolius), the aromatic coastal rosemary (Westringia dampieri), coastal sword-sedge (Lepidosperma gladiatum), seaberry saltbush (Rhagodia baccata), and thick-leaved fan-flower (Scaevola crassifolia) can be found. On the salt lake shores an array of salt-water tolerant plants such as samphires, grey salt bush, and sedges can be found.

A well-known flower native to Rottnest Island, the Rottnest Island daisy (Trachymene coerulea subsp. coerulea), is actually a member of the carrot family, although it resembles a true daisy in its form. Fields of these bright purple flowers appear in spring and areas of Rottnest are transformed into carpets of purple. Although the daisy can be seen in most areas of the island, the dune areas behind Henrietta Rocks and Parker Point are especially attractive.

In addition to Rottnest Island's native woodland species there are many introduced varieties such as Norfolk Island pines, Moreton Bay figs, Aleppo pines, olive trees, palm trees and tuarts. Other introduced plants include two varieties of onion weeds that are primary colonisers, and hare’s tail grass (Lagurus ovatus).

The Rottnest Island Authority has been undertaking woodland restoration on Rottnest since 1963. Woodland restoration activities include seed collection, propagation, planting and weed control. In earlier years, tree species not naturally occurring on Rottnest such as tuart (Eucalyptus gomphocephala) and coastal moort (Eucalyptus utilis) were planted in large stands. Apart from these stands not being representative of the natural habitat, many of these non-native species are not suited to the Island’s harsh conditions. Species such as tuart have high water demands and as a result put additional pressures on Rottnest’s limited groundwater supply.

Since 1995, only the two tree species native to the Island, Rottnest Island Pine and Rottnest Island Tea Tree, have been planted. Woodland restoration on Rottnest to date has predominantly involved planting within fenced restoration areas in order to exclude quokkas from grazing on the seedlings.

Trails are free and bring so many benefits to our community by providing opportunities to have fun, get fit, socialise, explore and challenge yourself. But they also have to be managed and maintained which only is made possible through terrific sponsors, donations and/or volunteering.
