The Big Blue

Journey to Australia's southern coast and uncover one of its best-kept secrets - a natural phenomenon called the "Bonney Upwelling" that sparks a feeding frenzy all the way up the food chain to the planet's largest living creature, the Blue Whale. As long as two buses with a mouth big enough to capture 50 tonnes of seawater, a feeding Blue Whale is a sight to behold. Filmed in Hi Def, this blue-chip natural history documentary captures, for the first time, the extraordinary spectacle of this unique event.
