Victoria is the southernmost mainland state of Australia. With an area of {{cvt|227444|km2}}, it is Australia's sixth largest state/territory, comparable in size to the island of Great Britain or the U.S. state of Utah. It is bound to the northwest by South Australia, directly north by New South Wales, and also shares a maritime border with Tasmania across the Bass Strait to the south. Most of Victoria's northern border lies along the Murray River. The eastern half of the state is dominated by the Australian Alps and the surrounding highlands (plateaus and hills) of the Great Dividing Range, which also to a lesser extent extend far into the west of the state and ease off after The Grampians. By comparison the north and northwest of the state is extremely flat with little prominence.

Approximately 80% of Victoria's population lives around the coasts of the Port Phillip Bay and (to a lesser extent) Western Port Bay in the south-central region, chiefly in the state's two largest cities, Melbourne (state capital) and Geelong.

Victoria has a varied climate despite its small size. It ranges from semi-arid temperate with hot summers in the north-west, to temperate and cool along the coast. Victoria's main land feature, the Great Dividing Range, produces a cooler, mountain climate in the centre of the state. Winters along the coast of the state, particularly around Melbourne, are relatively mild (see chart at right).

The coastal plain south of the Great Dividing Range has Victoria's mildest climate. Air from the Southern Ocean helps reduce the heat of summer and the cold of winter. Melbourne and other large cities are located in this temperate region.

The Mallee and upper Wimmera are Victoria's warmest regions with hot winds blowing from nearby semi-deserts. Average temperatures exceed {{convert|32|°C|0}} during summer and {{convert|15|C|F}} in winter. Except at cool mountain elevations, the inland monthly temperatures are {{convert|2|-|7|C-change|F-change|0}} warmer than around Melbourne (see chart). Victoria's highest maximum temperature of {{convert|48.8|C|F}} was recorded in Hopetoun on 7 February 2009, during the 2009 southeastern Australia heat wave.{{cite web|url=http://www.bom.gov.au/climate/extreme/records/national.pdf|title=Rainfall and Temperature Records: National|publisher=Bureau of Meteorology|access-date=8 June 2018|archive-date=27 March 2015|archive-url=https://web.archive.org/web/20150327211715/http://www.bom.gov.au/climate/extreme/records/national.pdf|url-status=live}}

The Victorian Alps in the northeast are the coldest part of Victoria. The Alps are part of the Great Dividing Range mountain system extending east–west through the centre of Victoria. Average temperatures are less than {{convert|9|C|F|0}} in winter and below {{convert|0|C|F|0}} in the highest parts of the ranges. The state's lowest minimum temperature of {{convert|−11.7|°C|1}} was recorded at Omeo on 15 June 1965, and again at Falls Creek on 3 July 1970.

= Rainfall =

Rainfall in Victoria increases from south to the northeast, with higher averages in areas of high altitude. Mean annual rainfall exceeds {{convert|1800|mm|in|abbr=off}} in some parts of the northeast but is less than {{convert|280|mm|in|abbr=on}} in the Mallee.

Rain is heaviest in the Otway Ranges and Gippsland in southern Victoria and in the mountainous northeast. Snow generally falls only in the mountains and hills in the centre of the state. Rain falls most frequently in winter, but summer precipitation is heavier. Rainfall is most reliable in Gippsland and the Western District, making them both leading farming areas. Victoria's highest recorded daily rainfall was {{convert|377.8|mm|in|abbr=on}} at Tidal River in Wilsons Promontory National Park on 23 March 2011.

File:Victoria_summer.jpg|Average January maximum temperatures:
Victoria's north is almost always hotter than coastal and mountainous areas.

File:Victoria_winter.jpg|Average July maximum temperatures:
Victoria's hills and ranges are coolest during winter. Snow also falls there.

File:Victoria_rainfall.jpg|Average yearly precipitation:
Victoria's rainfall is concentrated in the mountainous north-east and coast.

Regional divisions

The geography of Victoria has several different divisions depending on the aspect of the geography in question. Geomorphological divisions are listed in the following sections. From a human geographical perspective, the state is divided up into the following regions:

= Central =

= East and South-East =

=North-East=

=North-West=

=West=

=South-West=

Eastern Uplands ([[Victorian Alps]])

=Topography and hydrology=

Centred on the main divide in eastern Victoria, the Eastern Uplands separate the streams and rivers draining north to the Murray-Darling Basin from those flowing southwards directly to the sea. It is the largest and most diverse geomorphic region in the State.

The main streams draining northwards are the Goulburn, Campaspe, Mitta Mitta, Kiewa, Loddon, Avoca, Wimmera, Ovens and King Rivers. The most important streams flowing southwards to the sea are the Latrobe, Thomson, Macalister, Mitchell, Tambo, Nicholson and Snowy Rivers and their tributaries. All these rivers, with the exception of the Snowy River, reach the sea through the Gippsland Lakes of south-eastern Victoria. Further east, the Bemm, Cann and Genoa Rivers flow directly into Bass Strait to drain the eastern division of the Eastern Uplands. The Yarra River, flowing into Port Phillip Bay, drains the southwest area of the Uplands. The south-west of the state is dominated by the Hopkins and Glenelg rivers. The longest river in Victoria is the Goulburn, which rises below the peak of Corn Hill (1,331 m) and flows into the Murray river near Echuca. It is over 650 kilometers long.

Major peaks on the Great Divide in the Eastern Uplands include Mount Cobberas (1,833 m) near the border with New South Wales, Mount Hotham (1,862 m) and Mount Howitt (1,746 m). Victoria's highest mountain, Mount Bogong (1,986 m), is just north of the main range on a ridge that separates the upper reaches of the Mitta Mitta River from the Kiewa River. Other prominent peaks are Mount Feathertop (1,922 m), also to the north of the Divide, and Mount Buller (1,804 m) to the north west of Mount Howitt. Mount Wellington (1,632 m) lies at the southern end of the Snowy Range. The highest point south of the main divide is Mount Reynard which lies at an elevation of 1,737 meters.

Dendritic patterns of narrow ridges and valleys are typical of the region and characterise much of the deeply dissected landscape on either side of the Great Divide. Occasional isolated summits such as Mount Buller and Feathertop stand above the remnant plateaus or broad ridges.

Extensive landscapes of low relief occur at higher altitudes in the form of plateaus such as the Bogong High Plains, the plateaus of Mount Buffalo (about 1,400 m) and the Baw Baw Plateau, which are collectively commonly referred to as “high plains”. Extensive plateaus at successively lower elevations also frequent the further they are from the main divide. These include the Pinnibar plateau in the north-east, Nunniong plains to the south (about 1,200 m), and the Koetong - Shelly, Wabonga and Strathbogie plateaus further north (about 600–1,100 m).

The northerly draining valleys widen and the stream gradients gradually decrease as they near the Riverine Plain to the north and west of the region. The lower reaches of these streams have flood plains of fine sediments flanked by several sets of terraces. Alluvial or colluvial formations emerge from minor valleys of small ephemeral streams that drain the interfluves of major valleys. The ridges, as they approach the lowland plains, give way to low hills which mark the later stages of erosion of the upland ridges.

The floodplain and terraces of the Murray River at Wodonga indicate the eastern edge of the Northern Riverine Plain and the northern edge of the Eastern Uplands, at which point the floodplain is only about 150 m above sea level, consequently causing the flow of the major river systems in the region to have carved deep, narrow valleys in their upper reaches over time where the gradients are much steeper than along the floodplains.

South of the Great Divide the river systems increase in gradient and valley depth, and as they approach the Eastern Plain, having narrower alluviated valleys than those in the north. Large lowland areas enclosed by steep ridges such as the Murmungee basin south of Beechworth and the Dargo area south of the Divide, occur in parts of the Eastern Uplands. These are found where more readily weathered and eroded rocks occur surrounded by resistant rocks. The southern boundary of the Eastern Uplands is the southern extremity of an uneven bench-like platform known as the Nillumbik Terrain, which can be traced bordering the Eastern Plain from near Orbost to the eastern suburbs of Melbourne. The Eastern Uplands extend to the coast from Cape Conran to Rams Head, where the Nillumbik Terrain is absent, and is fringed with coastal sand dunes in parts.

=Botany=

Tall, thick forests of Alpine Ash occur on the upper mountain slopes, while the world's tallest hardwood tree, Mountain Ash, is found at slightly lower altitudes in the west of the region, with a typical variety of mixed-species eucalypts in conjunction with Ti-Tree shrubs composing the remainder of the forested portion of the Eastern Uplands.

The high plains are dominated by grasslands, herbfields, and heath communities which are widespread in areas where cold air drainage limits woody plant growth, with sphagnum bogs and fens in permanently wet areas. Snow Gum woodlands occupy the rocky knolls and ridges above approximately 1400–1500 m.[http://www.dpi.vic.gov.au/DPI/Vro/vrosite.nsf/pages/landform_geomorphological_framework_1 DPI, Eastern Uplands]
