For Investors
A vacancy rate of 21.6% is the standout concern, substantially higher than the national average, indicating significant short-stay or seasonal turnover in the rental pool. Weekly rent of $335 against a $441,000 median implies a gross yield around 3.9%, which is lower than many regional WA markets. The renter share is 22.4%, well below the national average, meaning the tenant pool is thin. Development activity recorded 0 applications in the past 12 months, consistent with a suburb in a settled, slow-growth phase. The 26.7% annual turnover rate suggests a meaningful share of property changes hands, which provides acquisition opportunities but also reflects that residents do not stay indefinitely compared to more stable suburbs.

Tenure
Separate houses dominate at 95.7%, one of the higher detached rates nationally, with apartments at just 0.3%. The bedroom distribution skews large: 57.7% of dwellings have 4 or more bedrooms, 35.3% have 3, and only 5.0% have 2. Outright owners (38.9%) and mortgage holders (38.6%) are nearly equal, while renters make up 22.4%. This tenure split, combined with the high vacancy rate of 21.6%, suggests a portion of the owned stock operates as holiday or weekender properties rather than permanent rental supply. Monthly mortgage repayments average $1,824 and rent averages $335 per week, both below typical WA coastal town levels relative to income at the 47.5th household income percentile.

Frequently Asked Questions
Is South Yunderup a good suburb to live in?
South Yunderup suits buyers seeking space and affordability on WA's Peel coast. At a $441,000 median house price and a mortgage-to-income ratio of 27.8%, housing costs remain below stress thresholds. The trade-offs are limited public transport, no recorded schools within the suburb, and a high vacancy rate of 21.6% that signals seasonal rather than year-round community density. Median age is 47, making it one of WA's older suburban communities.
What is the median house price in South Yunderup?
The median house price is $441,000, estimated from 2025 rental data. Weekly rent averages $335 and monthly mortgage repayments average $1,824. At those figures, mortgage costs represent 27.8% of household income, below the 30% stress threshold. The suburb offers 4-plus bedroom homes for 57.7% of its detached stock, giving strong size-per-dollar value compared to Perth metro areas.
What schools are in South Yunderup?
No schools are recorded within the South Yunderup suburb boundary in this dataset. Families rely on schools in nearby Pinjarra and Mandurah.

Is South Yunderup good for property investment?
The investment case is mixed. Weekly rent of $335 against a $441,000 median implies a gross yield of roughly 3.9%, moderate by regional WA standards. However, a 21.6% vacancy rate, the highest signal in the suburb profile, indicates significant short-stay or unoccupied properties that can compress net rental returns. The renter share is just 22.4%, so the tenant pool is limited, and 0 development applications in the past 12 months points to no near-term supply pressure.

No forecast population data is available for South Yunderup in this brief. The current population is 3,860 across 23.37 km2. The suburb has a median age of 47, which is 7.0 years above the national figure, indicating an aging resident base.

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).
