Australia is recognized as a mega-diverse country, with Sydney being the fifth most biodiverse region, yet it faces significant biodiversity threats, including 267 threatened species and a high level of habitat destruction. The tourism industry, heavily reliant on biodiversity, contributes 24.2% to Australia's GDP, with international visitors spending $20.5 billion. To mitigate ongoing losses, solutions include creating wildlife corridors and promoting government initiatives to protect and restore habitats.
