Sullivan Bay, located just 1 km east of Sorrento on Victoria’s Mornington Peninsula, is a sheltered beach with historical significance as Australia’s first Victorian settlement site[1][2]. The bay features a narrow sandy shoreline fronted by expansive tidal sand flats, creating calm waters ideal for family-friendly wading and coastal walks[3][5]. Its proximity to Port Phillip Bay’s entrance provides a mix of serene views and accessibility, making it popular for both relaxation and historical exploration[2][4].
