Subdivision Minimum Lot Size by State

There is no single national minimum lot size for subdivision in Australia. Each state and territory sets its own through its planning instrument, and the figure changes with the zone and, in most places, with your council area or precinct. A block that is big enough on paper can still fail on frontage, shape, access, an averaging rule or servicing.

So "how big does a block need to be to subdivide?" has at least eight answers. This guide compares them, with the residential examples from our state guides and the other size tests that apply. Figures are current at October 2026.

Minimum lot sizes compared by state

State	Where the minimum is set	Residential examples in our guides (zone)	Notes
NSW	Lot Size Map in each council's Local Environmental Plan (LEP), plus LEP clauses	Newcastle LEP 2012 clause 4.1A: down to 200 m² where a dual occupancy or multi dwelling development is approved at the same time. Low and mid-rise housing areas: subdivision of a dual occupancy down to 225 m² and 6 m width per lot (R1, R2, R3)	Varies between councils and zones, and can differ within the same zone
VIC	Zone clause and its schedule in the council's planning scheme	General Residential and Residential Growth: no minimum in the zone clause. Neighbourhood Residential: the schedule may set one. Low Density Residential: the schedule area, or 0.4 ha without reticulated sewerage and 0.2 ha with it where none is specified	In General and Neighbourhood Residential, 400 m² is a garden area trigger for vacant lots, not a minimum
QLD	Each council's planning scheme, usually its reconfiguring a lot code, by zone and sometimes by precinct or overlay	Logan, Low density residential: 300 m² (small lot precinct), 400 m² (suburban), 1,000 m² (large suburban). Brisbane, Low-medium density residential (3 or 4 storey mix zone precinct): 120 m² where the site is more than 400 m walking distance from frequent public transport or centres, with design and servicing requirements	Set council by council
SA	Each zone's land division rules in the Planning and Design Code, sometimes with a Minimum Site Area or Minimum Frontage technical and numeric variation (TNV)	No single figure given: minimum site area and frontage differ by zone and by dwelling type	Check for a TNV over your land
WA	The density code (R-Code) in the local planning scheme, applied through Table D of the Residential Design Codes Volume 1 (10 April 2026)	R20: 350 m² minimum, 450 m² average. R30: 260 m² and 300 m². R40: 180 m² and 220 m². R12.5: 700 m² and 800 m²	Both the minimum and the average apply
TAS	State Planning Provisions of the Tasmanian Planning Scheme, zoned by each council's Local Provisions Schedule	General Residential: 450 m², 12 m frontage. Inner Residential: 200 m². Low Density Residential: 1,500 m², 20 m frontage	These are acceptable solutions. Kingborough still uses its own interim scheme
ACT	Planning (Subdivision) Technical Specifications 2026, under the Territory Plan 2023	RZ1: 350 m². RZ2: 300 m². RZ3: 275 m². RZ4 and RZ5: 250 m²	In force from 1 July 2026. Areas exclude any battle-axe handle
NT	Table A to clause 6.2.1, Part 6 of the NT Planning Scheme 2020	Zone LR: 800 m² (compact-growth greenfield areas: average 600 m², no lot under 450 m²). Zone LMR: 300 m². Zones MR and HR: 800 m²	A 450 m² Zone LR minimum has been proposed but is not in force

What the figures mean in each state

New South Wales. Read the LEP text as well as the map, because many LEPs have clauses that vary the minimum. The low and mid-rise housing figures apply only within 800 metres walking distance of nominated town centres and stations in Greater Sydney, the Central Coast, the Lower Hunter and Newcastle, and Illawarra-Shoalhaven. On the Northern Beaches, a draft LEP would allow an R2 dual occupancy to be subdivided into lots of at least 400 m², but it is not in force (Northern Beaches draft LEP). See How to subdivide land in New South Wales.

Victoria. Where the zone clause sets no minimum, lot area is still assessed: even a two-lot subdivision in the residential zones must address Clause 56.04-2 (lot area and building envelopes). Rural zones and the Urban Growth Zone have their own rules. See How to subdivide land in Victoria.

Queensland. On the Gold Coast, three overlays can change the zone minimum. Brisbane's 120 m² lots took effect on 18 September 2026, and in its Low density residential zone, properties within 300 m walking distance of a shopping centre can now be subdivided to 300 m² (Brisbane's smaller lots). See How to subdivide land in Queensland.

South Australia. Subdivision is called land division here. Because the figures can differ for detached, semi-detached, row or group dwellings, the minimum depends on the homes planned as well as the zone. See How to subdivide land in South Australia.

Western Australia. The State Government has proposed abolishing the average lot size requirement for land coded R20 and below, so 700 m² R20 blocks could be split. As at 2 October 2026 no draft had been published, and amendments are anticipated to begin coming into effect from mid to late 2027, subject to consultation, endorsement and approval (WA R-Codes reform). See How to subdivide land in Western Australia.

Tasmania. Specific Area Plans in a council's Local Provisions Schedule can substitute, modify or add to the zone standards. Kingborough's interim scheme sets 450 m² for an ordinary General Residential lot, 550 m² for a corner or internal lot and 750 m² on land steeper than 1 in 5. See How to subdivide land in Tasmania.

ACT. Since 1 July 2026, RZ1 subdivision is permitted where each new block is at least 350 m², or where each new block contains a lawfully constructed dwelling (ACT Missing Middle reforms). Unit titling is a separate route: in RZ1 a standard block must be at least 600 m². See How to subdivide land in the ACT.

Northern Territory. Amendment PA2026/0205 would cut the Zone LR minimum to 450 m², excluding any battle-axe access strip, with a variation down to 405 m². The NT Planning Commission listed a hearing for 1 October 2026, and as at 2 October 2026 no ministerial decision had been published. The exhibited explanatory document says an 800 m² block could not be split under it (NT proposed 450 m² lots). See How to subdivide land in the Northern Territory.

Minimum lot size versus average lot size

Some rules set two tests: the smallest any one lot can be, and an average across the whole site.

WA. Table D sets both for every R-Code, and both apply, so a block can pass the minimum and still fail the average. At R20 the minimum is 350 m² and the average 450 m², so two lots generally need at least 900 m² of site area.
NT. In Zone LR greenfield areas identified for compact urban growth, lots average 600 m², with none under 450 m².

Elsewhere in our state guides the minimum is a per-lot figure.

Frontage, width and shape

Many rules also set a minimum frontage, width or depth, so a narrow block can meet the area and still not fit two lots side by side.

State	Frontage, width or shape examples in our guides
NSW	Low and mid-rise housing areas: 12 m width for a dual occupancy lot, 6 m per lot on subdivision
WA	Table D frontage for single houses: 10 m at R20, 8 m at R25, 17 m at R12.5
TAS	General Residential: 12 m frontage, and the acceptable solution requires each lot to fit a 10 m x 15 m building area no steeper than 1 in 5, clear of setbacks and easements. Low Density Residential: 20 m. Kingborough: 15 m
ACT	Compact block (250 m² or less): 17 m depth, 6 m width, slope no greater than 10%. Mid-sized (over 250 m² up to 500 m²): 25 m and 10 m. Large (over 500 m²): 28 m and 14 m
NT	Lots of 300 m² to under 450 m²: 10 m to a public road. 450 m² to under 600 m²: 13 m

Battle-axe lots: does the access leg count?

A battle-axe (rear) lot reaches the street through a driveway strip, called a handle, leg or access strip. Whether it counts towards the lot's area depends on the rule, and our state guides answer it only in some places:

NSW (Camden): Camden Council's DCP requires a battle-axe lot in its residential areas to be at least 600 m² excluding the access handle, with a handle at least 3.5 m wide where it serves one additional lot. Other councils set different figures.
WA: Table D gives a separate rear battle-axe lot area for single houses (450 m² at R20, 410 m² at R30), and the R-Codes have their own rules on how the access leg is counted. Operational Policy 2.2 says the Western Australian Planning Commission (WAPC) will not reduce minimum or average lot sizes for battle-axe lots, and the leg should be at least 4 m wide at R2 to R40.
TAS (Kingborough): access strips are excluded from the lot size.
ACT: minimum areas "exclude any battle axe handle".

Elsewhere, rear lots are controlled differently. In Logan's suburban precinct, a rear lot under 500 m² makes the application impact assessable. In Tasmania's General Residential Zone a rear lot usually relies on a performance criterion needing a frontage or right of carriageway at least 3.6 m wide. The NT scheme currently says "There are no battle-axe lots", unless a variation is approved.

When a block falls just short

A minimum is not always an absolute bar, but any flexibility is limited and is not an entitlement:

NSW: clause 4.6 of the LEP lets you ask council to vary the standard, though not for subdivision in some rural, environmental and large lot residential zones.
QLD: in Logan and on the Gold Coast, a lot below the minimum makes the application impact assessable. It must be publicly notified for at least 15 business days, and submitters can appeal.
SA: missing a deemed-to-satisfy or designated performance feature (DTS/DPF) figure in the Planning and Design Code is not an automatic refusal, but the proposal has to show the outcome is met another way.
WA: the WAPC can approve a lot up to five per cent below Table D where the R-Codes design principles are met, and Operational Policy 2.2 limits that to one lot in the subdivision.
TAS: in General Residential and Low Density Residential, a lot that misses the acceptable solution can be assessed against the performance criteria (in Low Density Residential, not less than 1,200 m²). Kingborough has no performance route below its minimums.
ACT: the Authority may approve a proposal that does not meet the technical specifications if it meets all relevant assessment outcomes.
NT: in Zone LR, no lot may be more than 5% below Table A, which is 760 m² against 800 m². In Zone LMR, the consent authority must not consent to a subdivision that is not in accordance with Table A.

Why "my block is big enough" is not the only test

Meeting the lot size is only the first hurdle. Other rules in our state guides can still stop a split:

Servicing. In WA's sensitive water resource areas, subdivision below one hectare should only occur with reticulated sewerage. Tasmania's General Residential acceptable solutions require each lot to connect to a full water supply service and reticulated sewerage, and NT lots in Zones LR, LMR, MR and HR are to be connected to reticulated services.
The house. In Tasmania's General Residential Zone an existing house is expected to be consistent with setbacks to the new boundary. The ACT's subdivision policy considers whether a dwelling can be accommodated on each new block.
Areas closed to new residential lots. In South East Queensland's Regional Landscape and Rural Production Area, reconfiguring a lot is prohibited unless an exemption applies, such as all lots being at least 100 hectares. In South Australia, a land division creating additional residential allotments in an environment and food production area must be refused.
Second dwellings. In NSW a lot with a secondary dwelling cannot be subdivided, and in Victoria a small second dwelling cannot be put on a separate lot.
Hazards, heritage and title. Bushfire, flood, heritage listings, protected vegetation, easements and covenants can all change the layout or stop it.

How to find the minimum lot size for your address

State	Where to check your zone and figure
NSW	NSW Planning Portal Spatial Viewer for zoning and minimum lot size, the LEP text, and a section 10.7 planning certificate from council
VIC	Planning property report from VicPlan, then your zone clause and schedule
QLD	Your council's planning scheme; in Brisbane, City Plan online shows zone, precinct and overlays
SA	South Australian Property and Planning Atlas (SAPPA) or the online Planning and Design Code
WA	Your council's local planning scheme map for the R-Code, Table D, and your certificate of title for lot area
TAS	A PlanBuild Tasmania Property Report; LISTmap boundaries are indicative only
ACT	ACTmapi
NT	The town planning zones layer of NT Atlas

Then check frontage, averaging and battle-axe rules too, and servicing. To see how these checks are set out for one property, view our sample report. A licensed surveyor or town planner can confirm the figure for your land.

Check your own block

A Subdivision Checker report applies these rules to one address: planning and zoning, heritage, environment, bushfire, flood, servicing, contamination and title, plus indicative costs. It is a starting point, not a substitute for a licensed surveyor or town planner. Order a report for your address.

Frequently asked questions

Is there a national minimum lot size for subdivision in Australia?

No. Each state and territory sets its own minimum through its planning instrument, and it varies by zone and often by council. In NSW it is the Lot Size Map in your council's LEP, in WA it follows the R-Code on your land, and in the ACT a territory-wide table sets a minimum for each residential zone.

How big does a block need to be to subdivide?

It depends on your state, zone and, in most places, your council. As examples from our state guides: at R20 in WA two lots generally need at least 900 m² because of the 450 m² average; in Tasmania's General Residential Zone the acceptable solution is 450 m² per lot; in the ACT each new RZ1 block needs at least 350 m² unless each contains a lawfully constructed dwelling; and in an established NT Zone LR suburb each lot needs to be at least 760 m².

Does a battle-axe access leg count towards the minimum lot size?

It depends on the rule that applies. Camden Council's DCP in NSW requires a battle-axe lot of at least 600 m² excluding the access handle; in WA the R-Codes have their own rules on how the access leg is counted, so check them for your code; the Kingborough Interim Planning Scheme in Tasmania excludes access strips; and ACT minimum block areas exclude any battle-axe handle.

Can I subdivide if my block is just under the minimum?

Sometimes. NSW councils can consider a clause 4.6 request to vary the standard. In Logan and on the Gold Coast, a lot below the minimum makes the application impact assessable. In WA the WAPC can approve one lot up to five per cent below Table D. In NT Zone LR a lot can be no more than 5% below the Table A minimum. None of these is an entitlement.

Are minimum lot sizes changing?

In some places. Brisbane's 120 m² lots in part of the Low-medium density residential zone took effect on 18 September 2026, and the ACT's RZ1 minimum of 350 m² took effect on 1 July 2026. The Northern Beaches draft LEP, WA's proposal to drop the average lot size for R20 and below, and the NT's proposed 450 m² Zone LR minimum were not in force when checked in early October 2026.

How do I find the minimum lot size for my address?

Look up your zone, and any precinct, overlay or variation, on your state's planning map, then read the rule for that zone in your state's planning instrument. Check frontage, averaging and battle-axe rules too. A licensed surveyor or town planner can confirm the figure for your land.
