Sunday, 7pm, National Geographic Any program with HG Nelson at the helm will be fun and this doesn’t disappoint. With his trademark ocker humour he brings to life a collection of Australian inventions that have put us on the map and changed lives. He kicks off with the ute — the half-car, half-truck invented by Ford after a farmer wrote to the chief executive in 1932 saying he needed something that would ‘‘ take the Mrs to church on Sundays and the pigs to market on Mondays’’. As HG points out, ‘‘ Australians are an inventive mob’’; our brightest sparks have come up with the Esky, in-vitro fertilisation and ultrasound technology, the wine cask (sometimes known as the Dapto briefcase) and, perhaps not so dazzling, the Splayd. The list continues, complete with archival footage and interviews with some of the inventors. Younger family members may enjoy this mini-lesson in Australian history too. Pity it’s a one-off.
