Marking the Bicentenary of Tasmania Becoming Its Own Colony

Today, 3 December 2025, Tasmania marks a milestone that is both quiet and profound: the 200th anniversary of the day this island first stood apart. When Van Diemen’s Land was formally proclaimed a separate colony, distinct from New South Wales.

It was on 3 December 1825, at Government House in Hobart Town (near Franklin Square), that Governor Sir Ralph Darling read a proclamation giving effect to an Order in Council issued in London six months earlier. That Order, made under the New South Wales Act 1823, recognised that the island’s expanding settlements, legal institutions and economy required a system of administration shaped by local circumstances rather than distant oversight from Sydney.

From that day forward, Van Diemen’s Land ceased to be a remote dependency. It became a colony in its own right. What turns 200 in 2025 is not Tasmania itself, nor its settlement, nor its modern government, but the moment Tasmania began the long evolution toward the distinct civic identity and governance that define our state today.

Why This Anniversary Matters

For many Tasmanians, “separation from New South Wales” may sound like a detail hidden in the margins of history. Yet in truth, it marks the beginning of a uniquely Tasmanian voice in the machinery of government. Before 1825, almost all decisions of consequence, from judicial appeals to public administration, were ultimately directed by Sydney.

But the island was changing. The early British footholds at Risdon Cove in 1803, Hobart Town in 1804, and the northern settlement at Port Dalrymple (in the area that would later develop into Launceston) that same year had grown into permanent communities with expanding agriculture, trade and population. Van Diemen’s Land was no longer merely a penal outpost; it was shaping into a unique society in its own right, shaped by its own people.

The 1825 proclamation acknowledged that reality. It established the island’s own Legislative Council, confirmed the authority of its Governor, and consolidated its Supreme Court, giving Van Diemen’s Land the administrative tools and justice system to chart its own course.

The People Behind the Moment

The separation of Tasmania from New South Wales in 1825 was shaped under one Crown, across two hemispheres and three capitals. From the decisions made in London and Sydney to the proclamation read here in Hobart.

In London, King George IV and Colonial Secretary Lord Bathurst authorised the legal instruments that created the new colony. In Sydney, Governors Sir Thomas Brisbane and Sir Ralph Darling oversaw the transfer of authority, with Darling personally travelling to Hobart Town to proclaim the separation. Wouldn’t it have been amazing to stand there?

Here on the island, Lieutenant-Governor George Arthur, Chief Justice John Lewes Pedder, Attorney-General Joseph Gellibrand, and the inaugural members of the Legislative Council formed the nucleus of the new government. Their actions, along with petitions from settlers seeking greater local control, laid the constitutional foundations of modern Tasmania.

From Colony to Community

The decades following separation saw Tasmania develop institutions that would shape its civic life for generations. Newspapers, schools, voluntary organisations and commercial enterprises emerged alongside growing towns and farmlands. In 1856, the colony achieved responsible self-government, adopted the name Tasmania, and established the parliamentary system we know today.

Seen in this broader arc, the bicentenary of 1825 could be seen to be about celebrating “Tassie turns 200,” but also, it’s marking the moment our island began its own path of administration and identity, distinct from New South Wales. Of course, Tasmanian statesmen were among the leading voices in the formation of what would become modern Australia in 1901 – a federation of Australian states with a clear delineation of roles and responsibilities for the states and the Commonwealth.

A Day Worth Marking – Tasmania Day

As we mark the bicentenary of 3 December 1825, we Tasmanians have a great opportunity to pause and reflect on a pivotal moment in our constitutional story. Whether the day is known Tasmania Day, or some other name, its purpose would be the same: to recognise the moment our island first stood apart, and we began to shape our own future. There are a number of regional show day holidays in Spring that are no longer used and may be worth repurposing into one unified state holiday that is all about Tasmania. Alternatively, there is Recreation Day and Regatta Day which are half day holidays in the North and South. This could be a way to have one unified state day.

Two hundred years on, the spirit of that community stepping forward to take responsibility for its own direction still runs deep with us today.

I have no doubt that we live in the best place in the world. 200 years from now, our descendants will still live in the best place in the world if we remember and honour where we came from and work together to look after our place, our advantages and most importantly, our people.
