Leabrook is a smaller community of 1,605 — about 43% of the South Australia suburb median (3,699) — so investors should factor in the narrower buyer pool and longer average time-on-market. Households here earn $88,036/year on average — 9% above the SA suburb median of $80,964 — a modest premium that supports resilient owner-occupier demand. Median rent of $308/week (~$1,335/month) covers only 62% of the median mortgage of $2,140/month — the remaining $805/month must be funded from other income, so this suburb tilts toward capital growth rather than yield. At 5 km from the Adelaide CBD, Leabrook sits inside the high-demand inner ring — properties here compete directly with the city's employment, transport and amenity networks. Only 36% of dwellings are separate houses (vs 73% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.

Limited buy-and-hold upside: a small population of 1,605 means liquidity is thin and capital growth tends to lag the wider South Australia market over full cycles.
Weak cash flow: $308/week rent covers only 62% of the $2,140/month median mortgage — a $805/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.
Only 36% of dwellings are separate houses (vs 73% SA median) — this is a unit and townhouse market, where cosmetic flips struggle against body-corporate restrictions, thinner after-reno uplift and competing new supply.

Leabrook scores 65/100 on our EquitySight investment framework — a good rating. That score is driven by a population of 1,605, median household income of $88,036/year and median weekly rent of $308. Whether it fits your portfolio depends on whether you are targeting cash flow, capital growth, or a value-add renovation — all three are scored with suburb-specific numbers elsewhere on this page.
The main demand drivers in Leabrook are proximity to Adelaide (5 km), an above-state-median household income of $88,036/year, a dwelling mix that is 36% separate houses, roughly 1 schools and 1 parks within the catchment. Together these shape both owner-occupier and tenant demand and are the factors we weight most heavily in the suburb's investment score.
Leabrook has a usual resident population of approximately 1,605, compared with a South Australia suburb median of 3,699 — placing it in the lower half of the state's suburbs by size. Population is the clearest proxy for market depth: more residents mean more transactions and typically a shorter average days-on-market on resale.
Leabrook sits 5 km straight-line from the Adelaide CBD. This is inner-ring territory — pricing competes directly with established Adelaide employment nodes.
The most recent census recorded a median weekly rent of $308 in Leabrook, equating to approximately $16,016/year in gross rental income (state median $320/week). Market rents have typically drifted above the recorded figure — verify against current listings on realestate.com.au and Domain before making an offer.
The median monthly mortgage repayment in Leabrook is $2,140, or approximately $25,680/year (vs $1,616/month state median). Stress-test your own borrowing at rates 1–2 percentage points above today's to make sure you can still service the loan through an RBA tightening cycle.
A median weekly rent of $308 works out to $1,335/month, covering 62% of the median mortgage repayment of $2,140/month. That leaves a $805/month shortfall (around $9,660/year before tax benefits), so a typical owner-occupier-priced property here is negatively geared. Actual cash flow depends on your deposit, loan terms, ownership costs and marginal tax rate — run the full numbers in our rental yield calculator.
The main risks are a thin buyer pool (1,605 residents), interest-rate sensitivity on the $2,140 median mortgage, a unit-heavy dwelling mix (36% houses) where body-corporate costs and apartment supply affect resale, the broader South Australia market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
