Slacks Creek
All four SEIFA indices sit in decile 1, the most disadvantaged tier nationally, yet the $394,000 median house price keeps Slacks Creek one of Logan's more accessible detached-housing markets. The contrast resolves in the labour profile: Labourers (691), Community workers (528) and Machinery operators (495) lead the occupation mix, university qualifications at 18.4% run 11.7 points below national, and the unemployment rate of 11.1% is well above average. Overseas-born residents at 33.2% are 11.6 points above national, anchored by English ancestry (3,211) alongside Samoan, Arabic and Mandarin language communities. Population has barely moved over a decade (-0.3%), and the aging trajectory shows the senior share up 5.0 points.

Estimated from rent (2025)
The $394,000 median (estimated from 2025 rents) makes Slacks Creek attractive to first home buyers priced out of inner Brisbane. Stock is overwhelmingly family-oriented: 78.5% separate houses against just 2.4% apartments, with three-bedroom homes at 60.9% and four-plus bedrooms at 24.3%. That suits the average household size of 2.7, slightly above the national figure. Monthly mortgage repayments of $1,430 produce a mortgage-to-income ratio of 25.4%, just below the 30% stress threshold, which is manageable because entry prices are low rather than because incomes are high. With household income in the 31st percentile, affordability here rests on cheap purchase prices, and ownership splits 21.9% outright and 33.6% mortgaged.

For Investors
Renters make up 44.5% of households, a deep tenant pool, and weekly rent of $310 against the $394,000 median produces a gross yield near 4.1%, far higher than premium Brisbane suburbs. Rent has grown 12.7% recently, supporting income returns. The vacancy rate of 6.2% is on the higher side and signals softer tenant demand than tighter markets. Overseas migration adds 128 residents a year while internal migration removes 128, leaving population essentially flat, so capital growth depends on Logan-wide momentum rather than local scarcity. Development activity is brisk with 148 applications in 12 months, though samples skew to roof and deck building work rather than new dwelling supply.

Demographics
The median age of 35 is 5 years below national, pointing to a younger, family-stage population. Overseas-born residents at 33.2% are 11.6 points above national, with English ancestry leading at 3,211, followed by Scottish (734) and Irish (721). Samoan (117) is the top non-English language, ahead of Arabic (54), Mandarin (48) and Korean (47), reflecting strong Pacific Islander and Middle Eastern migrant communities unusual for outer Brisbane. Christianity (4,254) dominates religion, with Islam (712) a notable second. University qualifications at 18.4% are 11.7 points below national, consistent with a trades and service workforce. Couples with children (2,950) far outnumber couples without (1,534), the inverse of gentrifying inner suburbs.

Tenure
Tenure splits 44.5% renting, 33.6% mortgaged and 21.9% owned outright, a renter-heavy mix for a detached suburb. The stock is 78.5% separate houses, 19.1% semi-detached and only 2.4% apartments, with three-bedroom dwellings at 60.9% and four-plus at 24.3% dominating the size profile. The $394,000 median is low by Brisbane standards, and both housing stress indicators sit below threshold: rent-to-income at 23.8% and mortgage-to-income at 25.4%. Despite affordable prices, IER decile 1 reflects limited economic resources, because household income in the 31st percentile keeps spare capacity thin even when repayments are modest. Affordability has improved over the decade, from 53.6% to 49.8%.

Economy & Employment
Healthcare leads employment at 18.3% (424 workers), followed by Construction at 10.7% (248), Education at 10.5% (243), Retail at 8.8% (205) and Manufacturing at 7.7% (179), a blue-collar and service mix with little professional concentration. Labourers (691) top the occupation list, ahead of Community and Personal workers (528) and Machinery operators (495), with Professionals only fifth at 484. This composition explains all four SEIFA deciles landing at 1: the IEO score of 876 and IRSAD of 860 reflect lower education and income. Unemployment at 11.1% is well above national, and participation at 49.7% is below average, partly because 3,053 residents are not in the labour force. Real income fell 1.4% over the decade, eroding purchasing power.

Transport to Work
Car dependence is near total, with 86.6% driving to work against just 3.0% on public transport and 1.4% walking or cycling, reflecting an outer suburb built around the motorway corridor rather than transit. The average household size of 2.7 is slightly above national, fitting the family demographic. Affordability is the core draw: rent-to-income at 23.8% sits comfortably below the 30% stress line, and the $310 weekly rent is well under inner-Brisbane levels. The trade-off is the SEIFA profile, with all four indices in decile 1, and an unemployment rate of 11.1% above the national average. Volunteering at 10.9% and a stable resident base, 76.6% staying put, point to community continuity despite the disadvantage measures.

Population Forecast
+0.12%/yr
(+13 people/yr)
EstablishedPopulation growth is minimal at 0.12% per year, roughly 13 people, with a 10-year change of just -0.3%, effectively flat. The medium forecast lifts population from 10,811 in 2025 to only 10,842 by 2031. Overseas migration of 128 a year is the sole growth driver, exactly offset by internal outflow of -128, signalling residents leaving for other parts of Queensland as new arrivals replace them. The gentrification score of 0 confirms no gentrification underway. The trajectory is aging: the senior share rose 5.0 points while the working-age share fell 1.8 points, suggesting an established population staying put rather than turning over, with the turnover rate at 23.4% below more transient markets.

What schools are in Slacks Creek?
The data brief does not list schools within the Slacks Creek boundary, so families typically rely on schools in neighbouring Logan suburbs. With three-bedroom homes at 60.9% of stock and couples with children numbering 2,950, school access in the wider area is a key consideration for buyers.
Is Slacks Creek safe?
Verified crime statistics are not available in the data brief for Slacks Creek, so a safety rating cannot be given here. Context worth noting: all four SEIFA indices sit in decile 1 and unemployment is 11.1%, factors that often correlate with crime, though 76.6% of residents stay put year to year.
Is Slacks Creek good for property investment?
The 44.5% renter share gives a deep tenant pool, and $310 weekly rent against a $394,000 median yields about 4.1% gross, with rents up 12.7% recently. The 6.2% vacancy rate is elevated and population is flat at 0.12% annual growth, so income beats capital growth here.

How much development is happening in Slacks Creek?
There were 148 development applications lodged in the past 12 months, an active level for an outer Brisbane suburb. Most samples are building work such as roof replacements and deck additions rather than new dwellings, so housing supply is growing slowly against flat 0.12% population growth.
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.
