Property market overview for this South Australian suburb.
This market is the suburb as the publisher names and groups it in its own release. The boundary is the publisher’s naming, not a boundary APRIQ drew and not an ABS or postal polygon.
Population grew +1.1% over the year to 30 June 2025, against +1.5% for Australia over the same period.
Net internal migration was the largest component of that change.
Dwelling approvals were −27.0% against the twelve months before. Approvals are permission to build, not completed dwellings.
Completions in the March quarter 2026 were equivalent to 84% of commencements, for South Australia. These figures compare pipeline flows and do not track individual approved dwellings through construction.
Achieved rents moved +26.3% over the year, against +5.7% for the middle suburb in South Australia.
These signals are shown separately so you can see what is driving the market. Explore them under Demand & supply below.
At $505 a week, Mannum is higher than 20% of the 224 SA suburbs we hold.
Rents there are up 26.3% over the past year, faster than South Australia as a whole (up 3.7%).
Based on 25 new leases. That is a small sample, so read the trend rather than the latest number.
The most common new lease there was a four-bedroom house, at $550 a week across 15 of them.
In June quarter 2026, the median weekly rent rose 5.2% on the quarter before, from $480 to $505. Across the 72 quarterly changes held here, 47 were larger.

The Australian Bureau of Statistics does not publish population for suburbs. What is shown is the figure for Mannum, the statistical area containing Mannum — it describes that wider area, not this suburb.
Moderate
How fast the population is growing, against the national rate.
| Population growth, Mannum | +1.1% | the year to 30 June 2025 |
|---|---|---|
| Population growth, Australia | +1.5% | the year to 30 June 2025 |
Strong when growth is at least half a percentage point above the national rate, weak when at least half a point below, moderate in between. Population is one ABS instrument measured the same way everywhere, so a market compares to Australia.
Net internal migration
Which component moved the population most over the latest year the ABS splits it.
| Natural increase, Mannum | −35 | the year to 30 June 2025 |
|---|---|---|
| Net internal migration, Mannum | +95 | the year to 30 June 2025 |
| Net overseas migration, Mannum | +13 | the year to 30 June 2025 |
The largest of natural increase, net internal migration and net overseas migration by absolute size, so a large outflow is named rather than hidden inside a net total. This states which component was largest. It says nothing about why anyone moved.
Contracting
Whether dwelling approvals are running above or below the year before.
| Dwellings approved, Mannum | 111 | June quarter 2026 |
|---|---|---|
| The twelve months before, Mannum | 152 | a year earlier |
| Change on the year before, Mannum | −27.0% | June quarter 2026 |
Expanding above +10%, contracting below −10%, stable in between, comparing twelve months of approvals against the twelve before them. An approval is permission to build, not a dwelling. Where a market is smaller than the areas the Australian Bureau of Statistics counts approvals for, this is a blend of those areas' own changes, weighted by how much of each the market covers — not a count of approvals here.
Moderate
How much housing is being finished, against how much is being started.
| Dwellings completed, South Australia | 3,102 | March quarter 2026 |
|---|---|---|
| Dwellings started, South Australia | 3,686 | March quarter 2026 |
| Completions as a share of commencements | 84% | March quarter 2026 |
Strong at or above 95% of commencements, weak below 80%, moderate in between — completions in the quarter compared with commencements in the same quarter, both stated beside this rule. These figures compare pipeline flows and do not track individual approved dwellings through construction.
High
How fast achieved rents are rising, against the rest of the state.
| Rent change over a year, Mannum | +26.3% | June quarter 2026 |
|---|---|---|
| Rent change over a year, the middle suburb in South Australia | +5.7% | June quarter 2026 |
High when rents rose at least one percentage point faster than the state, low when at least a point slower, moderate in between. Compared against the state rather than the nation because each bond authority defines its own series: changes compare, levels do not.
Limited
How much of this market's picture was measured at this market's own geography.
| Demand evidence | measured for a larger area containing this market | how it was made |
|---|---|---|
| Components present | 5 of 5 | on this page |
Broad where the demand evidence was published for this geography and most components are present; partial where it was derived through an official ABS correspondence; limited where it describes a larger area containing this market, or where components are missing. This says nothing about how many observations sit behind any single figure — that is Sample strength, a separate reading.
A sale-price series APRIQ can publish is not currently available for this market. Current rent, demand and supply data remain available on this page.
Rising faster than most of South Australia
How rents here moved over a year, against the typical suburb in South Australia.
| Rent change over a year here | +26.3% | June quarter 2026 against a year earlier |
|---|---|---|
| The middle suburb in South Australia | +5.7% | June quarter 2026 against a year earlier |
| Difference | +20.5 percentage points | June quarter 2026 against a year earlier |
| Markets in the comparison | 224 | June quarter 2026 against a year earlier |
The difference between this market’s one-year rent change and the middle change across every suburb the same publisher reports, in percentage points: 3 or more above is well above, 1 above is above, within 1 either way is in line. Changes are compared within one state because each bond authority defines its own series — movement may be compared between them, the rent itself may not.

Growing about as fast as Australia
How fast the population is changing in Mannum, the wider area this market sits inside, against how fast Australia is changing.
The Australian Bureau of Statistics does not publish population for suburbs. What is shown is the rate for Mannum, the statistical area containing Mannum — it describes that wider area, not this suburb.
| Annual population growth, Mannum | +1.1% | the year to 30 June 2025 |
|---|---|---|
| Australia, the same year | +1.5% | the year to 30 June 2025 |
| Difference | −0.5 percentage points | the year to 30 June 2025 |
| Growth a year over five years | +1.1% | the five years to 30 June 2025 |
The difference between this market’s annual population growth and Australia’s, in percentage points: 1.5 or more above is well above the national rate, 0.5 above is above it, within 0.5 either way is in line with it, and a fall is named as a fall. Both figures are ABS estimated resident population at 30 June, the same instrument measured the same way, so they may be compared directly.
Counted for Mannum on Census night, 10 August 2021. A Census count is a stock on one night, not a series: it cannot show a trend, and five years on it describes 2021, not today. It is here because how many households there are and how many people share a dwelling are the denominators every demand question eventually needs.
| Households — occupied private dwellings | 1,258 | one count: an occupied private dwelling on Census night is the ABS definition of a household |
|---|---|---|
| Average household size | 2.1 people | per occupied private dwelling, across 1,258 of them |

Approving well above the national rate
How many dwellings Mannum — the wider area this market sits inside — approved over twelve months for every thousand residents, against the national rate. Approvals are permission to build, not completed dwellings.
The Australian Bureau of Statistics does not publish dwelling approvals for suburbs. What is shown is the rate for Mannum, the statistical area containing Mannum — it describes that wider area, not this suburb.
| Approved dwellings per 1,000 residents, Mannum | 15.8 | the twelve months to June 2026 |
|---|---|---|
| Australia, the same twelve months | 7.4 | the twelve months to June 2026 |
| Change on the twelve months before | −27.0% | the twelve months to June 2026 against the twelve months to June 2025 |
| People added per dwelling approved | 0.5 | the year to 30 June 2025 |
This market’s approved dwellings per thousand residents divided by Australia’s: twice the national rate or more is well above it, a quarter above is above it, within a fifth either way is in line, and below four fifths is below. Both are ABS building approvals over the same twelve months. An approval is permission to build — some of it lapses, and the rest completes months or years later — so this describes a pipeline and never housing that exists.
Counted for Mannum on Census night, 10 August 2021. The stock every approval above eventually adds to, as it stood on one night in 2021. The occupied count is the households figure under Demand — the ABS definition makes them one count, so it is printed once rather than twice. The occupied and unoccupied counts are separately rounded by the ABS and do not exactly sum to the total, so no missing figure is derived here.

No APRIQ forward rent forecast is published for Mannum yet. The forecasting model remains in historical backtesting.
The method’s public record so far, across every market at once and clearly a backtest, not a prediction: at 1 quarter ahead, 83.8% of 10,476 graded backtests landed inside their ranges, at a median width of ±7.9%.

Thin
How many observations sit behind the current figure on this page.
| New leases behind the current figure | 25 | June quarter 2026 |
|---|---|---|

| How current | The latest quarter published anywhere | June quarter 2026 |
| Origin | As the publisher published it | June quarter 2026 |
| Knowability | Dated by the publisher’s own release timing | June quarter 2026 |
Strong needs 200 or more new leases behind the current figure; moderate needs 50. Fewer than that reads as thin: one unusual property can move the figure. A withheld count cannot earn better than thin, because a suppressed number is unknown rather than small. How current the figure is, is a separate fact stated as dates beside this reading, never folded into this word.
Which period the current rent figure describes, how it sits against the newest quarter published anywhere, and whose clock dated it — as dates, because a graded word would hide exactly the part worth checking.
