Well 'nature-based' tourism is put simply, geotourism! Take Canberra's Tidbinbilla's Nature Reserve as an exemplar - a 'unique place to experience nature and culture', one of many 'geosites' in our national capital, refer presentation by Douglas Finlayson  https://lnkd.in/gN5FtUnu

Other geosites include the National Rock Garden (located in the National Arboretum) and not forgetting the expansive Geological TimeWalk  https://lnkd.in/gfEhtCwd managed by Geoscience Australia.

VisitCanberra is leading the development of a long-term tourism strategy for the Canberra region in the Australian Capital Territory that links to the recently-released national strategy for Australia’s visitor economy (THRIVE 2030) that will be used to inform the development of the ACT’s 2030 Tourism Strategy. This includes Action 7.5 to 'grow and develop high-quality products and experiences around unique Australian locations and themes, including approaches which integrate sustainable nature tourism with economic opportunities for Traditional Owners, and capitalising on emerging tourism trends such as geotourism.’
