Roseville Chase

Household income in the 99.5th percentile nationally makes Roseville Chase one of the wealthiest communities in Australia, yet the suburb has a population of only 1,618 spread across 1.26 km2. The median house price reached $3,867,750 in 2025, up 21.8% from $3,175,000 in 2024, a one-year gain that few markets matched. Separate houses make up 95.8% of dwellings, an exceptionally high share compared to Sydney inner suburbs, and 63.3% of homes have four or more bedrooms. The median resident is 45 years old, five years above the national figure, and the area holds to that profile over time, with 87.6% of residents staying put year to year.

At $3,867,750, the median house price in Roseville Chase is one of the highest on the lower North Shore. Prices rose 21.8% in a single year from $3,175,000 in 2024 to $3,867,750 in 2025, well above the national median. Monthly mortgage repayments average $4,000, and the mortgage-to-income ratio sits at 22.9%, below the 30% stress threshold despite the very high purchase price, because household incomes at the 99.5th percentile nationally are exceptional. The stock is almost exclusively separate houses at 95.8%, with 63.3% of homes having four or more bedrooms, meaning buyers compete for large family homes rather than apartments. Ownership is the norm: 48.1% own outright and 42.0% carry a mortgage, leaving only 9.9% renting.

For Buyers

At $3,867,750, the median house price in Roseville Chase is one of the highest on the lower North Shore. Prices rose 21.8% in a single year from $3,175,000 in 2024 to $3,867,750 in 2025, well above the national median. Monthly mortgage repayments average $4,000, and the mortgage-to-income ratio sits at 22.9%, below the 30% stress threshold despite the very high purchase price, because household incomes at the 99.5th percentile nationally are exceptional. The stock is almost exclusively separate houses at 95.8%, with 63.3% of homes having four or more bedrooms, meaning buyers compete for large family homes rather than apartments. Ownership is the norm: 48.1% own outright and 42.0% carry a mortgage, leaving only 9.9% renting.

For Investors

The investment case in Roseville Chase is anchored in capital growth rather than yield. Weekly rent of $925 against a $3,867,750 median implies a gross yield well below 2%, lower than most comparable Sydney suburbs. The 3.9% vacancy rate is moderate and the renter share at 9.9% is very thin, so tenant demand is limited. Development activity recorded 28 applications in the past 12 months, with recent CDC approvals including secondary dwellings and new house builds, suggesting a slow but active infill market. The 21.8% price growth over 2024-2025 is the primary driver for investors willing to hold. High outright ownership at 48.1% means stock rarely changes hands, which keeps supply tight and supports long-run price growth compared to higher-turnover suburbs.

Economy & Employment

Professional and technical workers lead local industry at 23.1% of employed residents (144 people), followed by Finance at 14.1% (88) and Healthcare at 12.2% (76). By occupation, Professionals account for 301 workers and Managers for 234, together representing the majority of the employed base. These two groups align with household incomes in the 99.5th percentile nationally. Full-time employment runs at 63.6% and unemployment is 3.8%, low by national standards. Participation rate of 59.4% is moderate, partly because 444 residents are outside the labour force, consistent with early retirement and high wealth typical of a suburb at this income level. Weekly personal income of $1,197 and family income of $4,399 sit far above state and national medians.

Transport to Work

Car dependency is high: 86.6% of residents drive, and public transport accounts for only 4.5% of journeys, which is below the Sydney metropolitan average. Walking or cycling covers 3.7% of trips. The density of 1,280 people per km2 is low relative to other suburb profiles, which reflects the large-lot detached house pattern. No schools are recorded inside the suburb boundary in this dataset, so families rely on institutions in neighbouring areas such as Roseville and Lindfield. Housing stress indicators are well below thresholds: rent-to-income at 23.0% and mortgage-to-income at 22.9% are both comfortable given the 99.5th-percentile income base. Volunteering reaches 21.3% of residents, notably high compared to state averages, and only 3.0% of residents need daily assistance.

Frequently Asked Questions

Is Roseville Chase a good suburb to live in?

Household income sits in the 99.5th percentile nationally, 95.8% of dwellings are separate houses, and 87.6% of residents stay year to year, pointing to strong liveability. The main constraint is a very high median house price of $3,867,750.

What is the median house price in Roseville Chase?

The median house price reached $3,867,750 in 2025, up 21.8% from $3,175,000 in 2024. Monthly mortgage repayments average $4,000. Despite the high price, the mortgage-to-income ratio sits at 22.9%, below the 30% stress level, because household incomes are in the 99.5th percentile nationally.

What schools are in Roseville Chase?

No schools are recorded inside the Roseville Chase suburb boundary in this dataset. Families rely on schools in neighbouring areas such as Roseville and Lindfield. The suburb's education level is very high, with 65.3% of residents holding university qualifications, which is 35.2 percentage points above the national average.

Is Roseville Chase safe?

Detailed crime statistics are not available for Roseville Chase in this dataset. As an indirect signal, household incomes sit in the 99.5th percentile nationally, only 3.0% of residents need daily assistance, and the suburb's 87.6% residential stability rate is well above typical urban areas, all consistent with a low-disadvantage environment.

Is Roseville Chase good for property investment?

The 21.8% price growth from $3,175,000 to $3,867,750 in one year is the headline investment signal. However, weekly rent of $925 against that median implies a gross yield well below 2%, lower than most Sydney alternatives. The 9.9% renter share limits tenant demand. The investment case rests on capital growth in a supply-constrained market of large detached homes.

What languages are spoken in Roseville Chase?

About 33.5% of residents were born overseas, which is 11.9 percentage points above the national share. English is dominant, with Cantonese (45 speakers) and Mandarin (45) the most common non-English languages.

How much development is happening in Roseville Chase?

There were 28 development applications lodged in the past 12 months, including complying development certificates for new dwellings and secondary dwelling approvals. Activity is modest relative to the suburb size, consistent with an established low-density area where 95.8% of dwellings are already separate houses on large lots.

How to read these comparisons

Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.

Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.

Data sources: ABS 2021 Census (demographics, income, tenure), state Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
