Bass Strait in the context of "Australia (continent)"

Tasmania (/tæzˈmeɪniə/; palawa kani: Lutruwita) is an island state of Australia. It is located 240 kilometres (150 miles) to the south of the Australian mainland, and is separated from it by the Bass Strait. The state encompasses the main island of Tasmania, the 26th-largest island in the world, and the surrounding 1000 islands. It is Australia's smallest and least populous state, with 573,479 residents as of June 2023. The state capital and largest city is Hobart, with around 40% of the population living in the Greater Hobart area. Tasmania is the most decentralised state in Australia, with the lowest proportion of its residents living within its capital city.

Tasmania's main island was first inhabited by Aboriginal peoples, who today generally identify as Palawa or Pakana. It is believed that Aboriginal Tasmanians became isolated from mainland Aboriginal groups around 11,700 years ago, when rising sea levels formed Bass Strait.

Victoria, commonly abbreviated as Vic, is a state in southeastern Australia. It is the second-smallest state (after Tasmania), with a land area of 227,444 km (87,817 sq mi); the second-most-populous state (after New South Wales), with a population of over 7 million; and the most densely populated state in Australia (30.6 per km). Victoria's economy is the second-largest among Australian states and is highly diversified, with service sectors predominating.

Victoria is bordered by New South Wales to the north and South Australia to the west and is bounded by the Bass Strait to the south (with the exception of a small land border with Tasmania located along Boundary Islet), the Southern Ocean to the southwest, and the Tasman Sea (a marginal sea of the South Pacific Ocean) to the southeast. The state encompasses a range of climates and geographical features from its temperate coastal and central regions to the Victorian Alps in the northeast and the semi-arid northwest.

Boundary Islet, historically known as North East Islet, is a 2-hectare (4.9-acre) islet in the Hogan Island Group of Bass Strait, at a latitude of 39°12′ S, about 56 kilometres (35 mi) east of the southernmost point of mainland Victoria. The islet straddles the maritime border of the Australian states of Victoria and Tasmania, hence the name.

The Tasmanian portion of the islet forms that state's North East Islet Nature Reserve, gazetted on 5 April 1978. The reserve's name was conferred prior to the islet's change of name, to Boundary Islet, under Tasmanian legislation. This change was gazetted on 28 March 1990.

Port Phillip (Kulin: Narm-Narm) or Port Phillip Bay is a horsehead-shaped enclosed bay on the central coast of southern Victoria, Australia. The bay opens into the Bass Strait via a short, narrow channel known as The Rip, and is completely surrounded by localities of Victoria's two largest cities — metropolitan Greater Melbourne in the bay's main eastern portion north of the Mornington Peninsula, and the city of Greater Geelong in the much smaller western portion (known as the Corio Bay) north of the Bellarine Peninsula. Geographically, the bay covers 1,930 km (750 sq mi) and the shore stretches roughly 264 km (164 mi), with the volume of water around 25 km (6.0 cu mi). Most of the bay is navigable, although it is extremely shallow for its size — the deepest portion is only 24 m (79 ft) and half the bay is shallower than 8 m (26 ft). Its waters and coast are home to seals, whales, dolphins, corals and many kinds of seabirds and migratory waders.

Before European settlement, the area around Port Phillip was divided between the territories of the Wathaurong (west), Wurundjeri (north) and Boonwurrung (south and east) people, all part of the indigeous Kulin nation. The first Europeans to enter the bay were the crews of HMS Lady Nelson, commanded by John Murray and, ten weeks later, HMS Investigator commanded by Matthew Flinders, in 1802. Subsequent expeditions into the bay took place in 1803 to establish the first settlement in Victoria, near Sorrento, but was abandoned in 1804. Thirty years later, settlers from Tasmania returned to establish Melbourne (now Victoria's capital city) at the mouth of the Yarra River in 1835, and Geelong at Corio Bay in 1838. Today, Port Phillip is the most densely populated catchment in Australia with an estimated 5.5 million people living around the bay; Melbourne's suburbs extend around much of the northern and eastern shorelines, and the city of Geelong sprawls around Corio Bay in the bay's western arm.

The Rip is the narrow waterway entrance connecting the Bass Strait to the Port Phillip Bay in southern Victoria, Australia, and is the only route of maritime transport and thus seaport access into Melbourne and Geelong, Victoria's two largest cities and homes to Australia's largest and sixth-largest ports. Geographically, it is a roughly triangular area of water between Point Nepean on the Mornington Peninsula, Shortlands Bluff and Point Lonsdale on the Bellarine Peninsula, with these three headlands forming the Heads. Because of the strong oceanic tides being funnelled into the bay through this relatively narrow channel, and a high rocky seabed, the Rip is a dangerous stretch of water and has claimed numerous ships and many lives in history.

The Mornington Peninsula is a peninsula located in the south of Greater Melbourne, Victoria, Australia. It is surrounded by Port Phillip to the west, Western Port to the east and Bass Strait to the south, and is connected to the mainland in the north. Geographically, the peninsula begins its protrusion from the mainland in the area between Pearcedale and an area north of Frankston. The area was originally home to the Mayone-bulluk and Boonwurrung-Balluk clans, and formed part of the Boonwurrung nation's territory prior to European settlement.

Much of the peninsula has been cleared for agriculture and settlements. However, small areas of the native ecology remain in the peninsula's south and west, some of which is protected by the Mornington Peninsula National Park. In 2002, around 180,000 people lived on the peninsula and in nearby areas, most in the built-up towns on its western shorelines which are sometimes regarded as outlying suburbs of greater Melbourne; there is a seasonal population of around 270,000. On 30 June 2017, the Mornington Peninsula population was recorded at 163,847 people. However, in the peak of summer the population increases to 225,000–250,000 people each year, so that it becomes the most populous coastal holiday area in Victoria, with a larger population than Hobart.
