  • The headline growth figure uses a repeat-sales index of all dwellings (the same homes resold), which removes mix-of-what-sold noise; the tiles compare 12-month medians per dwelling type, so the two can differ slightly.
  • Unit medians are yearly because strata volumes are low; treat them as indicative.
  • Quarters with fewer than three house sales are left off the chart; one sale does not make a market median.

Dee Why street by street

Across 45 streets with enough house sales to compare, five-year medians on actively trading streets run from $2,207,500 on McIntosh Road to $5,200,000 on Monash Parade.

  • A street needs at least 5 sales of a type in 10 years to get a median, so streets quieter than that are left out entirely. Rankings use house sales only, so unit-heavy streets and residential parks are not mislabelled as cheap streets.
  • The highlight cards quote each street's last-5-years median (at least 5 sales in that window), so they reflect prices a buyer could pay now; the table shows the full 10-year view.
  • Prices are as-paid and not inflation-adjusted.

  • House sales only, 24 months. The unit median has its own figure at the top of the page.
  • Chart covers $1,750,000 to $5,750,000: 8 of the 127 house sales fall outside it (the cheapest and dearest few) and are left out so a handful of outliers cannot distort the shape.

  • Figures labelled Dee Why are for the suburb boundary itself (ABS 2021 Census). Anything labelled SA2 or postcode covers a wider area: SA2 "Beacon Hill - Narraweena" and postcode 2099 both extend beyond Dee Why.
  • SEIFA decile 1 is the lowest tenth of Australian areas on that index and 10 the highest. The four indices measure different things and often disagree, which is why all four are shown: a suburb can rank high on education and occupation while ranking mid on economic resources.

  • ICSEA is ACARA's socio-educational index (average 1000). It describes the family backgrounds of the students enrolled, NOT how well a school teaches: a lower ICSEA means a less advantaged intake, not a worse school.
  • Percentiles are ACARA's own national ranking, so the Australia bar is a published figure rather than our arithmetic. Each area shows the median of the mainstream schools sitting inside it; special schools are listed in the table but excluded from the medians.
  • Catchments are NSW Department of Education intake zones; always confirm an address with the school.

  • Counts are BOCSAR recorded incidents for January 2025 to December 2025 at LGA and postcode grain: both cover several suburbs, so they include neighbours of Dee Why.
  • Rates divide incidents by resident population (ABS 2021 Census), so they are comparable between areas in a way raw counts are not. Every tier uses the same offences and the same 12 months for January 2025 to December 2025.
  • Two limits worth knowing: the rate counts residents only, so a postcode with a town centre, nightlife strip or shopping precinct carries crime generated by visitors against a small resident denominator and reads high; and the population is the 2021 Census, so a suburb that has grown fast since then reads high too.
