Going Under Down Under: Flank Margin Caves in Australia and New Zealand

Coastal carbonate rocks in Australia and New Zealand, with ages ranging from Oligocene to Pleistocene, contain numerous flank margin caves. In Australia, flank margin caves were found from near modern sea level up to elevations of 300 meters in eolianites of Pleistocene age and marine subtidal carbonates of Miocene age. Caves were explored in Victoria, southeastern Australia; Kangaroo Island, southern Australia; Rottnest Island, southwestern Australia; and Cape Range, northwestern Australia.
