Yass is a town on the periphery of the Southern Tablelands and South West Slopes of New South Wales, Australia. The name appears to have been derived from an Aboriginal word, "Yarrh", said to mean 'running water'.

The South Western Slopes, also known as the South West Slopes, is a region predominantly in New South Wales, Australia. It covers the lower inland slopes of the Great Dividing Range, extending from north of Dunedoo through central NSW and into northeast Victoria, meeting its southwestern end around Beechworth. More than 90% of the region is in the state of New South Wales and it occupies about 10% of that state.
