- 10. Western Australian shield ■ Occupies the western part of Australia ■ Covers about 50% of the continent ■ Extends from Indian oceanic coast to MacDonnell range. ■ The shield is divided into different physical features known as “lineaments”. ■ These include- uplands; intervening lowlands and deserts.

- 21. ■ It the middle lies BLUE MOUNTAIN; HEIGHT BETWEEN 900-1500 METERS ■ Highest peak MOUNT KOSCIUSKO (2234 meters); in the exterme SE of great dividing range. ■ In Victoria, the range turns towards west, lowered and terminates in low hills known as Grampians. ■ Tasmania island is an uplifted dome and a part of Great Dividind Range.
