Wildlife activity on Gabo Island follows distinct oceanic migrations and breeding seasons.
| Season / Months | Avian Activity | Marine & Mammal Activity | Botanical Highlights |
|---|---|---|---|
| Spring (Sept – Nov) | Hundreds of thousands of Short-tailed Shearwaters arrive from Alaska; Little Penguins commence egg incubation. | Humpback Whales migrate southwards with calves; Fur Seals bask on sunny granite platforms. | Coastal Pigface bursts into vivid magenta bloom across cliff crevices; heath flowers. |
| Summer (Dec – Feb) | Penguin and Shearwater chicks hatch; intense feeding flights and nightly arrivals at dusk. | Pods of Common and Bottlenose Dolphins forage in Santa Barbara Bay; White’s Skinks active on warm rocks. | White berries ripen on Coast Beard-heath; salt-tolerant herbs dry in seaside breezes. |
| Autumn (Mar – May) | Shearwater fledglings depart on trans-Pacific flight; adult Little Penguins undergo annual moult. | Northbound Humpback Whale migration begins past Cape Howe. | Coastal tussocks turn golden; autumn storms deliver heavy seas and sea spray. |
| Winter (June – Aug) | Shearwaters absent in North Pacific; Little Penguins return to burrows at dusk between winter feeding runs. | Southern Right Whales occasionally seen close inshore; Australian Fur Seals frequent outer reefs. | Winter gales sweep the island; lichens on pink granite glow in maritime moisture. |

Arctocephalus pusillus doriferus
Australian Fur Seals frequently haul out on the exposed pink granite shelves of Gabo Island and adjacent Tullaberga Island to rest, sunbathe, and forage.
Humpback Whale
Megaptera novaeangliae
Thousands of Humpback Whales migrate past Gabo Island each year, using the promontory of Cape Howe and Gabo as a natural coastal navigation point.

Liopholis whitii
A robust, sun-loving lizard commonly observed basking on the warm pink granite outcrops of Gabo Island on calm sunny days.
Coast Beard-heath
Leucopogon parviflorus
A dense, salt-hardy shrub with tiny white bearded flowers that forms the protective backbone of Gabo’s central scrub canopy.
