Rosetta

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

As of May 2026, AreaSearch estimates the population of Rosetta to be around 2,806 people. This figure reflects a decrease of 27 people since the 2021 Census, which reported a population of 2,833 people. The current resident population estimate of 2,805 by AreaSearch is based on examination of the latest ERP data release by the ABS in June 2025 and validation of an additional 48 new addresses since the Census date. This results in a population density ratio of 998 persons per square kilometer for Rosetta. While Rosetta experienced a 1.0% decline since census, the SA3 area achieved 1.1% growth, indicating divergent population trends. Overseas migration was the primary driver of population gains during recent periods.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022. For areas not covered by this data and to estimate post-2032 growth by age group, Tasmania State Government's Regional/LGA projections released in 2022 with a base year of 2021 are used, adjusted employing weighted aggregation methods from LGA to SA2 levels. Based on projected demographic shifts, Rosetta is expected to grow by just below the median rate of statistical areas across the nation, increasing by 128 persons to reach an estimated population of 3,047 by 2041. This reflects a total gain of 4.5% over the 16-year period.

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

Rosetta has seen approximately six new homes approved annually based on AreaSearch analysis of ABS building approval numbers. Around 34 homes were approved in the past five financial years, from FY21 to FY25, and three more have been approved so far in FY26. The population has declined recently, but development activity has been adequate relative to this decline, which is positive for buyers.

New dwellings are developed at an average expected construction cost of $279,000. This year, $5.8 million in commercial approvals have been registered, indicating the area's residential character. When compared to Greater Hobart, Rosetta shows about half the construction activity per person. Nationally, it places among the 33rd percentile of areas assessed, resulting in relatively constrained buyer choice and supporting interest in existing homes.

This level is below average nationally, reflecting the area's maturity and possible planning constraints. All new construction in Rosetta has been comprised of detached houses, preserving its suburban nature. This emphasis on detached housing attracts space-seeking buyers and demonstrates robust demand for family homes, with 79.0% of dwellings being detached at Census. With around 513 people per dwelling approval, Rosetta shows a developed market. According to the latest AreaSearch quarterly estimate, Rosetta is expected to grow by 127 residents through to 2041. With current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.

Rosetta has moderate levels of nearby infrastructure activity, ranking in the 41stth percentile nationally

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

Rosetta has a skilled workforce with essential services sectors well represented. The unemployment rate was 4.3% in the past year, with an estimated employment growth of 1.0%. As of December 2025, 1,352 residents were employed while the unemployment rate was 0.3% higher than Greater Hobart's rate of 4.0%.

Workforce participation was lower at 60.3%, compared to Greater Hobart's 63.7%. According to Census responses, only 7.6% of residents worked from home. Employment is concentrated in 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 has a limited presence with 9.3% employment compared to the regional average of 10.8%. The area appears to offer limited local employment opportunities. In the 12-month period ending in December 2025, employment increased by 1.0%, while the labour force rose by 0.4%, leading to a decrease in unemployment rate by 0.6 percentage points. This contrasts with Greater Hobart where employment rose by 0.1%, the labour force fell by 0.1%, and unemployment fell by 0.2 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 suggest that Rosetta's employment should increase by 6.6% over five years and 13.7% over ten years, based on a simple weighting extrapolation of industry-specific projections against the local employment mix.

Income levels sit below national averages according to AreaSearch assessment

AreaSearch's latest postcode level ATO data for the financial year ending June 30, 2023 indicates that Rosetta suburb had a median income among taxpayers of $47,532 and an average income of $51,560. These figures are below the national average. In comparison, Greater Hobart's median income was $54,577 with an average of $65,190 during the same period. Based on Wage Price Index growth of 10.95% since June 30, 2023, estimated incomes for Rosetta as of March 2026 would be approximately $52,737 (median) and $57,206 (average). According to Census 2021 income data, household, family, and personal incomes in Rosetta rank modestly, between the 34th and 36th percentiles. The largest segment of residents, comprising 32.8%, earns between $1,500 and $2,999 weekly (920 residents), which aligns with the regional trend where this cohort also represents 32.2%. After accounting for housing costs, 85.0% of income remains for other expenses.

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

Rosetta's dwelling structure, as per the latest Census, consisted of 79.3% houses and 20.7% other dwellings (semi-detached, apartments, 'other' dwellings). In contrast, Hobart metro had 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. The median weekly rent figure was $350, matching Hobart metro's figure. Nationally, Rosetta's mortgage repayments were lower than the Australian average of $1,863, and rents were less than the national figure of $375.

Family households constitute 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 account for 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, 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%. This disparity presents both challenges and opportunities for targeted educational initiatives. Bachelor degrees are most common at 13.3%, followed by postgraduate qualifications (6.4%) and graduate diplomas (2.3%). Vocational credentials are prevalent, with 35.7% of residents aged 15+ holding such qualifications - advanced diplomas at 9.5% and certificates at 26.2%.

Educational participation is 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 57 different routes that collectively facilitate 4,092 weekly passenger trips. The average distance from a resident's home to the nearest transport stop is 163 meters, indicating excellent accessibility. In this primarily residential area, most commuting is outward-bound. Cars remain the primary mode of transport, used by 87% of residents, with buses accounting for 8%. On average, there are 1.5 vehicles per dwelling.

According to the 2021 Census, 7.6% of residents work from home, which may be influenced by COVID-19 conditions. Service frequency averages 584 trips per day across all routes, resulting in approximately 186 weekly trips per individual 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. The area has a considerably higher prevalence of common health conditions compared to averages, with older age cohorts experiencing this to an even greater extent. Only approximately 48% (~1,335 people) of Rosetta's total population has private health cover, which is lower than 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%), while 62.9% of residents claim to have no medical ailments, slightly lower than Greater Hobart's 65.5%. Working-age residents in Rosetta show a higher prevalence of chronic health conditions compared to averages. The area has 22.9% of residents aged 65 and over (642 people), which is higher than Greater Hobart's 20.0%. Health outcomes among seniors present some challenges, although they rank 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 population showed above-average cultural diversity, with 18.9% born overseas and 15.6% speaking a language other than English at home. Christianity was the main religion, accounting for 45.0%. The 'Other' religious category comprised 2.0%, higher than Greater Hobart's 1.1%.

In ancestry, the top groups were English (31.9%), Australian (28.3%), and Other (9.2%). Notably, Sri Lankan (0.3% vs 0.1%), Australian Aboriginal (3.4% vs 3.0%), and Korean (0.3% vs 0.2%) groups were overrepresented compared to regional averages.

Rosetta's median age exceeds the national pattern

Rosetta's median age in 2021 was 41 years, higher than Greater Hobart's average of 39 years and slightly above the national average of 38 years. The age profile showed that those aged 85 years and over made up 3.7% of the population, while those aged 25 to 34 years constituted 14.2%. Between 2021 and present, the proportion of individuals aged 35 to 44 years increased from 12.7% to 14.1%, while the share of those aged 55 to 64 years decreased from 12.1% to 10.8%. By 2041, demographic projections indicate significant changes in Rosetta's age structure. The number of individuals aged 45 to 54 years is projected to rise substantially by 212 people, increasing from 300 to 513. Conversely, both the 25 to 34 years and 65 to 74 years age groups are expected to decrease in numbers.
