In an emergency

Call 000 for police, fire or ambulance — Australia's emergency number works even with a weak signal, and without a SIM if any carrier has coverage.

You're in Yanchep National Park, Yanchep, WA. Mobile reception in this area is not guaranteed — this is exactly why the offline map and GPS position on this page work without signal.

Tell someone your plan and expected return time before you set off. A PLB is the most reliable backup where there's no reception at all.

Vulnerable (IUCN) — narrow coastal endemic

A tall eucalypt restricted to a narrow coastal strip of the Swan Coastal Plain running from Yanchep to Busselton, with outlying patches north to Geraldton. Tuart forest is a distinct, threatened plant community — Yalgorup National Park protects one of its significant remaining stands.

How to spot it

Grows 10-40m tall with rough, box-like bark. Glossy light-green oval-to-lance leaves 90-180mm long; white-cream flowers form unbranched in the leaf axils, followed by bell-shaped fruit.

Western Grey Kangaroo

Macropus fuliginosus

IUCN Least Concern▾

IUCN Least Concern

A large, common kangaroo of southern Australia, ranging from south of Shark Bay across coastal Western Australia and South Australia into western Victoria and the Murray-Darling basin; it does not occur in Tasmania or far north Queensland.

How to spot it

Distinguished from the eastern grey kangaroo by darker grey-brown fur, darker colouration around the head, and sometimes a blackish patch near the elbow. Males can be up to twice the size of females; look for them grazing in open woodland, coastal heath and farmland edges across the southern mainland.

Carnaby's Black-Cockatoo

Zanda latirostris

IUCN Endangered; EPBC-listed Endangered▾

IUCN Endangered; EPBC-listed Endangered

Endemic to south-western Australia's Wheatbelt and coastal plain, Carnaby's black-cockatoo has declined by more than 50% over the past 45 years due to widespread clearing of the eucalypt woodland and kwongan heath it depends on for nesting and feeding. Large flocks are a familiar sight over Perth's pine plantations and banksia woodlands outside the breeding season.

How to spot it

53-58cm, mostly greyish-black with fine pale scalloping, a short crest and a prominent white/off-white cheek patch and white tail band. The bill is comparatively short and stubby (compare to the longer-billed Baudin's black-cockatoo, which overlaps only at the eastern edge of its range). Call is a loud, wailing two-note 'wy-lah'. Look for them feeding on Banksia, Hakea and Grevillea seed pods, or flying over in noisy flocks at dusk heading to roost.
