Kakadu National Park

Australia's largest national park at 19,804 sq km, Kakadu National Park is a dual UNESCO World Heritage Site combining 20,000 years of continuous Aboriginal rock art with extraordinary wildlife density. Its vast floodplains host over 280 bird species—more than the Kimberley's total mammal count—and 60 mammal species across six distinct seasons. The 10,000 insect species support a food web that enables 8-meter saltwater crocodiles to thrive, surpassing #7 Whitsundays' marine richness in terrestrial biomass. With 1.5 million annual visitors exploring ancient galleries, Kakadu's cultural depth outperforms the average Australian park by offering 5,000 recorded art sites within a single accessible region.
