How do Victoria’s eastern and western upland regions differ?

The upland regions of Victoria, which form part of the Great Dividing Range, are divided into two distinct areas by the low, wide Kilmore Gap.1

The eastern and western regions differ primarily in their scale and elevation:

• Eastern Region: This area is more extensive and higher in elevation. It features several peaks exceeding 5,000 feet (1,500 metres), including the state's highest point, Mount Bogong (6,516 feet [1,986 metres]). The landscape includes high plateaus and has been heavily shaped by perennial streams fed by spring snowmelt.1
• Western Region: As the uplands arc westward, they become progressively narrower and lower. This region terminates in the Grampians and the Dundas Tableland. Its highest peak is Mount William, which reaches an elevation of 3,829 feet (1,167 metres).1

These uplands are a defining feature of the state's geography, contrasting with the surrounding plains and the varied landscapes found elsewhere in Victoria.12
