Tasmania's population growth has slowed significantly, raising concerns about the state's economic future. The once-booming migration to Tasmania, which saw a population increase of nearly 50,000 people between 2016 and 2021, has now plateaued, with an annual growth rate of just 0.3% in September 2025. This slowdown is expected to lead to natural population decline by 2028-29, as deaths outnumber births. The trend is particularly concerning for young adults, who are increasingly leaving Tasmania for opportunities elsewhere, both domestically and internationally. This brain drain is a significant challenge for the state's economy, as it exacerbates existing issues such as skill shortages and an aging population.
The reasons for this shift are multifaceted. On one hand, Tasmania's small-town charm, reminiscent of Melbourne in the 90s, with its friendly communities and affordable housing, has attracted young couples like Milly Willemsen and Nick Wagner. They found a sense of opportunity and a chance to 'buckle down' and build a life. However, on the other hand, the state's limited job prospects and the allure of sunshine and better opportunities in places like Queensland's Gold Coast have driven young Tasmanians like Ellie Warmbrunn to leave.
Despite the apparent population slump, Tasmania's infrastructure is adapting. The state has seen increased peak-hour traffic congestion and growth in outer suburbs, with the municipality of Clarence and Brighton north of Hobart experiencing significant population increases. However, this growth is driven more by interstate and overseas migration than by natural population growth, leading to increased demand for housing. The short-stay accommodation sector is particularly affected, with whole houses being lost to non-permanent occupancy.
The economic implications of this population slowdown are significant. Slower population growth means lower payroll tax, lower stamp duty, and lower consumer spending, which in turn reduces GST revenue. This is a critical source of revenue for the Tasmanian government, and the state's ability to grow its economy will depend on productivity improvements, which Tasmania has historically struggled with. Tasmanian Treasurer Eric Abetz argues that the economy has strengthened despite low population growth, citing a 1.1% growth in gross state product per capita.
However, the state's aging population poses a significant challenge. By 2050, the median age of a Tasmanian is predicted to be around 48, with 28% of the population over 65. This will lead to increased healthcare spending and skill shortages, with three wards of patients currently stranded in Tasmanian hospitals due to a lack of aged care facilities. The problem is costing the state $100 million annually, and Abetz urges the federal government to address it.
To attract more people to Tasmania, the government is focusing on improving basic services and infrastructure. Treasury papers suggest that lower population growth could improve housing affordability, which could lift interstate migration. The construction of the Macquarie Point stadium in Hobart is seen as a potential drawcard for young workers from across Australia. However, Lisa Denny warns that Tasmania will face competition from other major construction projects, such as those for the Brisbane Olympic Games.
Ultimately, the key to reversing the population outflow lies in improving education and health systems, according to independent economist Saul Eslake. He argues that better government services are essential to attracting and retaining younger people. Additionally, Dr. Denny suggests a shift in how decision-makers view an aging population, emphasizing the opportunities it presents for keeping people active and productive in the workforce.
In conclusion, Tasmania's population slowdown is a complex issue with far-reaching implications. While the state's unique appeal has drawn some residents, the challenges of a shrinking and aging population cannot be ignored. Addressing these issues will require a comprehensive approach, focusing on both economic incentives and the quality of life, to ensure Tasmania's long-term prosperity.
