Wild South: Volume 6

'City Under the Sea' (1992) - Undersea guides Wade and Jan Doak introduce us to the busy reefs of the Poor Knights Islands, one of the world's richest and most diverse realms. Could these underwater cities be as complex as our urban societies? Within this colourful metropolis we see how fish occupy their time commuting, seeking new homes, courting, and raising their young. 'Endless Summer' (1992) - Often making flights of over 15,000km, migrant wading birds descend on North Western Australia late each year seeking a summer haven during the harsh northern winter months. At Broome, over 30 species come to restore their energy, grow stunning plumage, and prepare for the long haul back to Northern breeding grounds. 'Castles of the Underworld' (1992) - Caves have captured the human imagination for millennia, evoking our fascination and fear of the underworld. In this spectacular look at New Zealand's limestone caves, we examine how extraordinary creatures have adapted to live in total darkness, and how cavers and scientists are pushing back the frontiers of darkness to reveal the complex ties that bind the fortunes of the cave world to the world above.
