Ecosystems Along the Surf Coast Walk

When I first laced up my boots for a day on the Surf Coast Walk, I thought I knew the Great Ocean Road — cliffs, beaches, the odd café at Aireys Inlet. But within a few kilometres, I realised I was walking through a patchwork of living ecosystems — dunes that breathe, heathlands that burn and bloom, and woodlands that hum with bird life. These ecosystems connect Bells Beach, Point Addis Marine National Park, Anglesea River, Aireys Inlet, and eventually blend into the Great Otway National Park.

Coastal Dune Systems — Nature’s Wind-Built Walls

If the Surf Coast had lungs, they’d be its dunes. Built grain by grain by salt winds off the Southern Ocean, these rolling sand ridges stretch from Torquay to Aireys Inlet, stabilising the coast and protecting inland habitats. Walk near Back Beach or Point Roadknight and see coastal spinifex, pigface, and coastal saltbush binding the sand and keeping erosion at bay. Beneath them, root networks hold against winter gales — without them, the Great Ocean Road itself would be at risk. Tip: Stay on designated boardwalks and tracks. One careless footstep can collapse a decade of slow dune growth.

Heathlands — The Floral Firekeepers

Beyond the dunes lies the coastal heathlands. Low, colourful shrubs form a buffer between dunes and woodland, thriving in sandy soils.
After winter rains, the heath bursts into colour — pinks, purples, and yellows of wattles, banksias, and tea-trees. These fire-adapted ecosystems need occasional burns to regenerate, but too-frequent fires can wipe out plant communities.
They’re home to small marsupials, skinks, and birds — some rare or endangered. The elusive coastal emu once roamed here before European settlement fragmented their habitat.

Eucalypt Woodlands — Shade, Scent, And Song

Cross into Great Otway National Park woodlands and the air thickens with eucalypt oil and leaf litter. Messmates and ironbarks sway over bracken and grass-trees, providing shade after the open dunes. Listen here — bird country: lorikeets screech, kookaburras cackle, and fairy-wrens flicker. These woodlands connect coastal habitats with inland forests like Melba Gully and Sabine Falls, forming wildlife corridors through the Otway Ranges. Picnic tip: Stop at Currawong Falls or the Sheoak Picnic Ground inland from Lorne for a shady lunch surrounded by grey gums and wattlebirds.

Rock Platforms And Intertidal Zones — Life Between Tides

Where land meets sea — at Bells Beach, Point Addis, or Guvvos Beach — every tide reveals a living mosaic: limpets, barnacles, crabs, starfish, sponges, and anemones clinging to rock crevices that flood twice daily. These intertidal zones are nurseries of the Southern Ocean, critical for marine biodiversity. Beneath the surface, algae feed invertebrates, which feed fish, which feed seabirds and seals. Always walk mindfully: wear grip shoes, don’t trample, and never collect shells or creatures.
Cape Otway Lighthouse

Coastal Cliffs And Headlands — Nature’s Edge

The cliffs of Victoria’s Surf Coast are nature’s ledger — each layer tells a story of ancient seas and shifting continents. From Eagle Rock near Aireys Inlet to Cape Otway Lightstation, sandstone and limestone cliffs host hardy succulents and nesting seabirds. On a windy day, stand at the Cape Otway Lighthouse or Gibson Steps and feel the power of the Shipwreck Coast. You’re standing on the “Otway Basin,” the same ancient structure reaching the Twelve Apostles. Safety tip: Stick to fenced lookouts and don’t go near cliff edges. Coastal erosion is sneaky, and one selfie too close can be fatal.

Rivers, Estuaries And Wetlands — The Water Threads

The Anglesea River, Aire River, and small streams thread freshwater through the coast. Estuaries filter sediment, shelter fish nurseries, and provide feeding grounds for waterbirds. Take the Aire River near Johanna Beach — frogs croak, egrets stalk the shallows, and kangaroos sometimes drink. Wetlands near Mara Creek and Anglesea Marshes attract migratory species like Latham’s snipe and local favourites like herons and spoonbills.

Wildlife Along The Walk

The Surf Coast Walk overlaps with some of southern Australia’s most biodiverse areas:

  • 48 threatened bird species
  • 16 threatened mammals
  • 5 reptiles
  • 3 fish
  • 3 amphibians
  • 8 invertebrates

Look out for echidnas in the woodlands, wallabies in the heath, and seals at Point Addis Marine National Park. During winter, migrating humpback whales and southern right whales pass offshore. Birdwatching tip: cliffs near Cape Otway and Aireys Inlet are hotspots for kestrels, wedge-tailed eagles, and nesting seabirds.

Threats To The Surf Coast Ecosystems

Erosion, weeds, overuse of trails, litter, and climate change are eating away at these systems. Rising sea levels threaten dunes and estuaries; uncontrolled fires disrupt heathland regeneration. Cliffs crumble faster with storm surge. Woodland corridors shrink as developments creep in. Parks Victoria and the Great Ocean Road Coast and Parks Authority monitor pressures, adjusting fire regimes, trail maintenance, and visitor education. Every walker plays a part. Staying on track, picking up rubbish, and respecting closures make a big difference.
How To Walk Responsibly — And Enjoy It

How To Walk Responsibly — And Enjoy It

  • Stay on marked tracks: Trampling off-path kills native plants and accelerates erosion.
  • Avoid cliff shortcuts: unstable and dangerous.
  • Carry reusable water bottles: avoid plastic in dunes.
  • Respect cultural sites: walk with awareness on Wadawurrung Country.
  • Check fire and park alerts before you go.
  • Support local conservation: buy coffee from eco-friendly cafés in Apollo Bay or Anglesea that donate to dune restoration.

The Surf Coast Walk connects to the Great Ocean Walk, the Otway National Park, and the wild cliffs of Port Campbell National Park. Your steps matter.

Seasonal Changes Along The Walk

Spring: wildflowers burst; birds nest; creeks run clear.
Summer: bring sunscreen and water; dunes dry out; snakes bask.
Autumn: milder days, calmer seas, fungi bloom near Otway Lightstation.
Winter: swells pound Bells Beach; wetlands brim; whales migrate past Cape Otway.

Eagle Rock Marine Sanctuary

A Personal Yarn

Near Aireys Inlet, dawn light turned Eagle Rock Marine Sanctuary cliffs gold. Surf below Bells Beach hissed like a giant kettle. Hooded plovers scuttled between tide lines — a reminder of how fragile it all is.
Later, a family asked if the track ahead was “safe for prams.” I grinned: “Safe, sure — just don’t let the mozzies hitch a ride.” This walk isn’t about ticking off landmarks — it’s about tuning into the pulse of Country. Every dune, tree, and tidepool is part of an ancient conversation.

FAQ

The full walk runs about 44 kilometres, from Torquay to Aireys Inlet, connecting to other trails leading toward the Great Ocean Walk.
Spring and autumn offer the best balance — mild temperatures, fewer flies, and blooming heathlands.
Yes — Southside Beach, Anglesea River, and Currawong Falls all have nearby picnic spots. Camping is available within Great Otway National Park and other state forest areas.
Absolutely, but choose patrolled beaches like Bells Beach or Anglesea Main Beach. Always check surf conditions and tide times.
Dogs are permitted on some sections (mainly near Torquay and Anglesea) but restricted within marine national park areas like Point Addis. Always check local signage.
