Tim and John bag Mt Kosciuszko, the third of their big peaks, but it is more of an amble than a climb. They 'recover' with a beer and an argument about the comparative merits of Sydney versus Melbourne. They go underground for a close-up investigation of the Snowy River Scheme and go hunting for the endangered corroboree frog. And when they get embroiled in a debate about brumbies in the high country, emotions run high.
Next stop is a visit to the mysterious natural feature on top of the Divide - Lake George, which seemingly appears and disappears by magic. Down the road they visit the Bradman Oval in Bowral to discuss sporting role models with Stuart McGill, and Tim takes to the nets for the first time. In the shadows of the Blue Mountains, they take a tour of the Penrith Panthers Rugby Leagues Club to look at the social cost of gambling, and they learn a thing or two about drag racing.
In the highlands, a visit to the Norman Lindsay Gallery leads to a discussion about wowserism, and a stop off at the Explorers' Tree leads Tim to declare that Wentworth, Blaxland and Lawson were over-rated!
John takes Tim on a sentimental tour of his birthplace, Lithgow, and in the Hunter Valley they look at the march of coal mining and the effect it is having on agriculture, tourism and the wine industry. Next, they travel through the Northern Rivers of NSW, and fly over Mt Warning in a microlight. Safely back on terra firma, they head to Wallangarra, a tiny town that played a special role in the Federation of Australia. Last stop is Tenterfield where John performs the famous Tenterfield Address, in the room where Henry Parkes first made it in 1889.
