The Winds of Jarrah (1983)

At least the title can be partly explained by noting that the film was produced by the Film Corporation of Western Australia, one of its only three films. Jarrah is the name of the eucalypt that grows in southern Western Australia, and the film was originally intended to be shot at Pemberton WA, among the jarrah trees. For reasons unknown to me, it was filmed in Dorrigo NSW. It is said to be the first film based on a Mills & Boon novel, which in this instance was The House in the Timberwoods by Joyce Dingwell, 1959. The first screenplay was written by husband and wife Anne Brooksbank and Bob Ellis, tho Egerton preferred his own version. It was shot in Panavision by Geoff Burton, but I believe never released theatrically, so the exquisite cinematography has never been seen by cinema audiences.
