How much does a 1→3 subdivision cost in Brisbane?

Scale infrastructure charges (paid on 2 new lots = ~$56K), surveying (more cost), and operational works (more services). Typical 1→3 Code Assessable subdivision: $180,000–$300,000 all-in excluding land.

Is Impact Assessable subdivision more expensive?

Yes — add $20,000–$50,000 in additional planning consultant time, public-notification advertising, longer IR cycles, and significantly longer holding cost (timeline extends 3–6 months minimum).

Do I pay infrastructure charges upfront?

No — the Infrastructure Charges Notice (ICN) is issued shortly after the development approval. Payment is required before the council seals the survey plan (i.e. before the new lots can be titled). Plan your settlement timing around this.

Variables that move the total

Service depth
Sewer/water connection runs over 50m, or under-road boring, can add $20–60K to operational works.
Slope / retaining
Sites with cross-fall >1:8 typically add $20–80K of retaining and earthworks.
Frontage and access
Battle-axe access handles need additional driveway and stormwater design (+$5–15K).
Tree removal / arborist reports
Significant tree removal triggers ecological reports (+$3–8K) and council conditions.
IR cycles
Each Information Request cycle adds 4–12 weeks of holding cost (+$3–10K) and consultant time (+$2–6K).

Council-by-council variation

Council	Note
Brisbane City Council	Highest infrastructure charges (~$28K/new lot) but most predictable approval timelines.
Logan City Council	~$20K/new lot, generally more permissive RoL rules in NGN precincts.
Moreton Bay	~$22K/new lot, most permissive RoL flexibility in SEQ for reduced minimum lot sizes.
Ipswich	~$18K/new lot — SEQ's lowest, paired with the lowest land prices.

What's NOT included in the total

Original land purchase price.
Stamp duty on land acquisition.
Building works on the new lots (sold vacant or built-to-sell).
