The San Remo jetty has anchored Bass Strait departures since the timber wharf was rebuilt in stone in 1956, replacing a nineteenth-century structure that served as the island's sole supply line before the bridge opened in 1940. Wildlife Coast Cruises began running the cape woolamai cruise from san remo route in 1991, mapping a twelve-kilometre coastal arc that threads between the basalt stacks of Seal Rocks and the weathered granite headlands where short-tailed shearwaters nest in burrows dug into clifftop heath. The company's twin-hulled vessels — purpose-built in 1989 and refitted with hydraulic viewing platforms in 2003 — carry cetacean research permits from Parks Victoria and collaborate with the Phillip Island Nature Parks marine mammal monitoring program, logging seal population counts and whale sightings that feed into quarterly Bass Strait biodiversity reports. Cape Woolamai's southern cliffs rise eighty-seven metres above the tide line, their granite faces carved by fifteen thousand years of post-glacial wave action. The headland marks the eastern boundary of Westernport Bay, where tidal flows meet the open Strait at a collision point visible from the deck as a permanent chop line. Australian fur seals — Arctocephalus pusillus doriferus — haul out on the wave-cut platforms of Seal Rocks between May and October, with colony numbers peaking near eight hundred individuals during the winter breeding window. The offshore islets also host little penguin breeding boxes installed by the Nature Parks in 2009, part of a fox-exclusion trial that has since raised fledgling survival rates by forty-one percent. The cruise route parallels the Summerland Peninsula's eastern shore, passing the exposed strata of Smiths Beach where Devonian sedimentary layers tilt at thirty degrees — evidence of tectonic folding that occurred when the Australian plate collided with the Pacific margin twelve million years ago. Guides point out the shearwater arrival pattern: birds return from the Bering Sea in September, synchronised within a forty-eight-hour window by mechanisms marine biologists have yet to fully decode. The san remo coastal tour operates year-round, though winter months offer the highest probability of humpback whale breaches — documented in seventy-three percent of July sailings since 2018, according to Wildlife Coast logbooks. The Marine Parade departure point sits at the western foot of the bridge, where the channel narrows to two hundred metres. Tidal velocity here reaches three knots on the spring ebb, creating upwellings that concentrate krill and juvenile fish — the dietary foundation for the resident seal population and the seasonal whale migrants that transit the Strait between Antarctic feeding grounds and subtropical calving waters off Queensland.
