Done the famous Big Five of Africa — lion, elephant, buffalo, leopard and rhinoceros?
Time to swap the khaki shorts and binoculars for diving suit and swimming goggles in pursuit of five other giants in Asia-Pacific.
Found in the oceans of Australia and islands further afield are some of world’s most iconic endangered marine species: the white shark, green turtle, the humpback whale,whale shark and the Australian sea lion.
As I discovered, swimming alongside them can be a life-altering experience, albeit one fraught with difficulties.
But it’s worth the effort.
