Rosetta

An assessment of population growth drivers in Rosetta reveals an overall ranking slightly below national averages considering recent, and medium term trends

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch since then, Rosetta's population is estimated at around 2,824 as of Feb 2026. This reflects a decrease of 9 people (0.3%) since the 2021 Census, which reported a population of 2,833 people. The change is inferred from the resident population of 2,811, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 48 validated new addresses since the Census date. This level of population equates to a density ratio of 1,005 persons per square kilometer, which is relatively in line with averages seen across locations assessed by AreaSearch. While Rosetta experienced a 0.3% decline since census, the SA3 area achieved 2.4% growth, highlighting divergent population trends. Population growth for the area was primarily driven by overseas migration, which was essentially the sole driver of population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, and to estimate growth by age group in the years post-2032, the Tasmania State Government's Regional/LGA projections, released in 2022 with 2021 as the base year, are adopted with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Considering the projected demographic shifts, a population increase just below the median of statistical areas across the nation is expected, with the suburb of Rosetta expected to grow by 112 persons to 2041 based on aggregated SA2-level projections, reflecting recording a gain of 0.9% in total over the 17 years.

The level of residential development activity in Rosetta is very low in comparison to the average area assessed nationally by AreaSearch

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Rosetta has seen around 6 new homes approved annually. Approximately 34 homes have been approved over the past five financial years, between FY-21 and FY-25, with 1 more approved so far in FY-26. The population decline in recent years has resulted in adequate development activity relative to other areas, benefiting buyers.

New dwellings are developed at an average expected construction cost value of $279,000. This financial year, around $5.8 million in commercial approvals have been registered, indicating the area's residential character. Compared to Greater Hobart, Rosetta shows about half the construction activity per person and ranks among the 33rd percentile nationally when assessed for buyer choice, suggesting relatively constrained options and supporting interest in existing homes. This level is below average nationally, reflecting the area's maturity and possible planning constraints.

New construction has been entirely comprised of detached houses, preserving Rosetta's suburban nature and attracting space-seeking buyers. The demand for family homes remains robust, with 79.0% of new constructions favouring detached housing compared to current patterns at Census. With around 501 people per dwelling approval, Rosetta indicates a developed market. According to the latest AreaSearch quarterly estimate, Rosetta is expected to grow by approximately 26 residents through to 2041. Given current construction levels, housing supply should meet demand adequately, creating favourable conditions for buyers and potentially allowing growth that exceeds current forecasts.

Rosetta has moderate levels of nearby infrastructure activity, ranking in the 48thth percentile nationally

Rosetta has seen below average employment performance when compared to national benchmarks

Rosetta's unemployment rate stands at 4.2%, as per AreaSearch's aggregation of statistical area data. As of September 2025, there are 1,311 residents employed with an unemployment rate of 4.2%, which is 0.2% higher than Greater Hobart's rate of 4.0%. Workforce participation in Rosetta is lower at 58.3%, compared to Greater Hobart's 63.8%.

According to Census responses, only 7.6% of residents work from home. The leading employment industries among Rosetta residents are health care & social assistance, public administration & safety, and retail trade. Manufacturing stands out with employment levels at 1.4 times the regional average. However, education & training is under-represented, with only 9.3% of Rosetta's workforce compared to Greater Hobart's 10.8%.

The area offers limited local employment opportunities, as indicated by the difference between Census working population and resident population. Between September 2024 and September 2025, Rosetta saw a labour force decrease of 1.2% and employment decrease of 0.7%, resulting in an unemployment rate fall of 0.5 percentage points. In contrast, Greater Hobart experienced employment falling by 0.7%, labour force contraction by 0.9%, and unemployment falling by 0.2 percentage points during the same period. National employment forecasts from Jobs and Skills Australia indicate a potential growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Rosetta's employment mix suggests local employment should increase by 6.6% over five years and 13.7% over ten years, though this is a simple extrapolation for illustrative purposes only.

Income levels sit below national averages according to AreaSearch assessment

The suburb of Rosetta had a median taxpayer income of $47,532 and an average income of $51,560 in the financial year 2023, according to postcode level ATO data aggregated by AreaSearch. This is lower than the national average, which contrasts with Greater Hobart's median income of $54,577 and average income of $65,190 during the same period. Based on a Wage Price Index growth rate of 9.6% since financial year 2023, estimated incomes for Rosetta as of September 2025 would be approximately $52,095 (median) and $56,510 (average). According to the 2021 Census, household, family, and personal incomes in Rosetta ranked modestly, between the 34th and 36th percentiles. Income brackets showed that 32.8% of Rosetta's population (926 individuals) fell within the $1,500 - $2,999 income range, which is consistent with broader trends across the metropolitan region showing 32.2% in the same category. After housing costs, 85.0% of income remained for other expenses.

Rosetta is characterized by a predominantly suburban housing profile, with above-average rates of outright home ownership

Rosetta's dwelling structures, as per the latest Census data, consisted of 79.3% houses and 20.7% other dwellings (semi-detached, apartments, 'other' dwellings). This compares to Hobart metro's figures of 85.3% houses and 14.7% other dwellings. Home ownership in Rosetta stood at 36.8%, with mortgaged dwellings at 35.0% and rented ones at 28.2%. The median monthly mortgage repayment was $1,517, aligning with Hobart metro's average, while the median weekly rent was $350, also matching Hobart metro's figure. Nationally, Rosetta's mortgage repayments were significantly lower than Australia's average of $1,863, and rents were less than the national figure of $375.

Rosetta has a typical household mix, with a higher-than-average median household size

Family households account for 69.2% of all households, including 27.0% couples with children, 29.3% couples without children, and 12.2% single parent families. Non-family households make up the remaining 30.8%, with lone person households at 26.7% and group households comprising 3.4%. The median household size is 2.5 people, which is larger than the Greater Hobart average of 2.4.

Rosetta faces educational challenges, with performance metrics placing it in the bottom quartile of areas assessed nationally

The area's university qualification rate is 22.0%, significantly lower than the SA4 region average of 32.8%. Bachelor degrees are most common at 13.3%, followed by postgraduate qualifications (6.4%) and graduate diplomas (2.3%). Vocational credentials are prominent, with 35.7% of residents aged 15+ holding them, including advanced diplomas (9.5%) and certificates (26.2%). Educational participation is high at 26.4%, comprising primary education (9.8%), secondary education (6.4%), and tertiary education (3.8%).

Educational participation is notably high, with 26.4% of residents currently enrolled in formal education. This includes 9.8% in primary education, 6.4% in secondary education, and 3.8% pursuing tertiary education.

Transport servicing is high compared to other areas nationally based on assessment of service frequency, route connectivity and accessibility

Rosetta has 22 active public transport stops, all of which are bus stops. These stops are served by a total of 57 different routes that facilitate 4,092 weekly passenger trips combined. The accessibility to these stops is rated as excellent, with residents typically living just 163 meters away from the nearest stop. As a predominantly residential area, most commuting in Rosetta is outward-bound. Cars are the primary mode of transport, used by 87% of residents, while only 8% use buses. On average, there are 1.5 vehicles per household.

According to the 2021 Census, which may have been influenced by COVID-19 conditions, just 7.6% of residents work from home. Across all routes, service frequency averages at 584 trips per day, equating to approximately 186 weekly trips per stop.

Health performance in Rosetta is well below average with considerably higher than average prevalence of common health conditions and to an even higher degree among older age cohorts

Rosetta faces significant health challenges according to AreaSearch's assessment. Mortality rates and chronic condition prevalence are substantially higher than average, with older age cohorts experiencing this to an even greater extent. Only approximately 48% of Rosetta's total population (~1344 people) has private health cover, compared to Greater Hobart's 51.7% and the national average of 55.7%.

The most prevalent medical conditions are arthritis (11.1%) and mental health issues (10.0%). Conversely, 62.9% of residents report being completely clear of medical ailments, slightly lower than Greater Hobart's 65.5%. Working-age residents display above-average prevalence of chronic health conditions. Rosetta has a higher proportion of seniors aged 65 and over at 23.1% (652 people), compared to Greater Hobart's 19.9%. Health outcomes among seniors present some challenges, ranking lower nationally than the broader population.

In terms of cultural diversity, Rosetta records figures broadly comparable to the national average, as found in AreaSearch's assessment of a number of language and cultural background related metrics

Rosetta's cultural diversity is notable, with 18.9% of its population born overseas and 15.6% speaking a language other than English at home. Christianity is the predominant religion in Rosetta, accounting for 45.0% of its population. However, the category 'Other' is disproportionately represented, comprising 2.0% compared to the regional average of 1.1%.

In terms of ancestry, the top three groups are English (31.9%), Australian (28.3%), and Other (9.2%). Some ethnic groups show significant variations: Sri Lankan at 0.3% (compared to 0.1% regionally), Australian Aboriginal at 3.4% (vs 3.0%), and Korean at 0.3% (vs 0.2%).

Rosetta's median age exceeds the national pattern

The median age in Rosetta is 41 years, which is higher than Greater Hobart's average of 39 years and the national average of 38 years. The age profile shows that those aged 85 and above make up 3.8% of the population, while those aged 25 to 34 comprise 13.9%. Since 2021, the percentage of the population aged 35 to 44 has increased from 12.7% to 14.5%, while the percentage of those aged 55 to 64 has decreased from 12.1% to 10.6%. The percentage of those aged 25 to 34 has also dropped, from 15.1% to 13.9%. By 2041, demographic projections indicate that the age group 45 to 54 will rise significantly, with an increase of 191 people (66%), from 290 to 482. Conversely, both the 0 to 4 and 5 to 14 age groups are projected to decrease in number.
