The sand at Hyams Beach is recognized by the Guinness World Records as some of the whitest in the world, consisting of pure silica.
Jervis Bay is a drowned river valley that formed when sea levels rose approximately 6,000 years ago.
The park is a primary site for humpback whale calving and resting during their annual northward migration.
The park contains rare remnant stands of littoral rainforest, an endangered ecological community in Australia.
Marine bioluminescence can occasionally be observed in the bay at night, caused by Noctiluca scintillans blooms.
The park's geology features Permian-aged sandstone and conglomerate layers that have eroded into unique sea caves and rock platforms.
It supports a high density of terrestrial orchids which bloom primarily in late winter and early spring.
The park acts as a land bridge between the coastal and hinterland habitats of the Illawarra escarpment.
Jervis Bay National Park is distinguished by its exceptionally white silica sands and high-contrast turquoise waters along the South Coast of New South Wales. The park protects a diverse ecosystem ranging from coastal heathland and ancient rainforests to salt marshes and mangroves. It is a critical habitat for threatened species including the eastern bristlebird and the long-nosed potoroo. The coastline features rugged sandstone cliffs and sheltered coves that serve as migratory transit zones for humpback whales. The region maintains significant cultural heritage sites associated with the Jerrinja people. Visitors access a network of tracks, including the Hyams Beach walking trail and the White Sands Walk. The park encompasses the northern and southern peninsulas of the bay, separated by the marine sanctuary area. Coastal vegetation is adapted to high salt exposure, creating low, dense scrub environments throughout the headlands.
