Griffiths Island Lighthouse (38°23′27.31″S, 142°15′18.84″E) (Goggle Maps) is the next lighthouse east of Whalers Bluff Lighthouse, which makes it the third lighthouse from the west on the Victorian coast.
Griffiths Island is home to migrating muttonbirds (short-tailed shearwaters), who arrive late in September and leave mid-April for their annual migration around the Pacific.
Google Earth has the wrong island pinpointed as Griffiths Island and Google Maps has it correct. Lady Julia Percy Island (38°25′02.66″S, 142°00′10.93″E) (Google Maps) lies about 20km from Port Fairy. According to the official Melbourne, Victoria, tourism website, Parks Victoria has counted 23,000 seals, making it the largest colony of Australian Fur Seals in the Southern Hemisphere. It is also home to muttonbird colonies, kestrels, swamp harriers, sooty oystercatchers, fairy penguins, lizards, sea birds, crayfish, and sharks (it's an axiomhave seal colony, will find sharks). It's also a good area for whale watching in the winter. Although I missed it myself, I would recommend a boat trip to LJP Island out of Port Fairy.
