<Li> In Tasmania, one of the states of Australia, the central Midlands region is in a strong rain shadow and receives only about a fifth as much rainfall as the highlands to the west . </Li> <Li> In New South Wales and Victoria (both states of Australia), the Monaro is shielded by both the Snowy Mountains to the northwest and coastal ranges to the southeast . Consequently, parts of it are as dry as the wheat - growing lands of those states . </Li> <Li> Also in Victoria, the western side of Port Phillip Bay is in the rain shadow of the Otway Ranges . The area between Geelong and Werribee is the driest part of southern Victoria: the crest of the Otway Ranges receives 2,000 millimetres (79 in) of rain per year and has myrtle beech rainforests much further west than anywhere else, whilst the area around Little River receives as little as 425 millimetres (16.7 in) annually, which is as little as Nhill or Longreach and supports only grassland . </Li> <Li> Western Australia's Wheatbelt and Great Southern regions are shielded by the Darling Range to the west: Mandurah, near the coast, receives about 700 millimetres (28 in) annually . Dwellingup, 40 km inland and in the heart of the ranges, receives over 1,000 millimetres (39 in) a year while Narrogin, 130 km further east, receives less than 500 millimetres (20 in) a year . </Li>
