New South Wales occupies about 10% of Australia and offers a diverse range of terrains and climates.
The Blue Mountains 60km west of Sydney offers the best bushwalking. Walking in summer is best avoided because it can be extremely hot up on the plateau. Snow can fall in the New England Tableland, the Barrington Tops and the central west towns of Bathurst and Orange during the Winter months.
In the subtropical north particularly around Lismore significant rain falls from February through to about June.
