Volume-builder base range with standard fixtures and finishes.
For this 4 bed, single storey build, Melbourne comes out roughly $46k to $74k more than Adelaide on the build alone. The base build contract is closer than the totals suggest — the gap sits in site costs, land and statutory lines.

Building Indemnity Insurance (BII) is required over $12,000 and is built into the contract sum.
South Australia has no growth-area infrastructure levy on a standard house block.
Regulator: VBA (Victorian Building Authority)
Domestic Building Insurance (DBI, via VMIA) is required over $16,000 and is built into the contract sum.

Common questions
Is it cheaper to build in Adelaide or Melbourne?
For a like-for-like standard home, Adelaide is generally cheaper than Melbourne. The gap comes mostly from labour rates, site costs on reactive-clay blocks, land in outer growth corridors, and Victorian statutory levies that South Australia does not have. The base build contract for a standard volume-builder home is closer than the headline totals suggest - the difference shows up in the top-up line items.
Why is the Melbourne build cost higher?
Three drivers push Melbourne above Adelaide: higher trade labour rates, higher site costs (reactive clay plus growth-corridor infrastructure), and Victorian statutory levies such as the GAIC in designated growth areas. Land in Melbourne outer suburbs also sits well above the Adelaide equivalent.
Are these figures a quote?
No. These are indicative 2026 ranges for a standard detached home built by a volume or project builder, GST inclusive. They are a planning guide only. Always get three written quotes from licensed builders, and confirm live grant and stamp-duty figures with RevenueSA (SA) or the State Revenue Office (VIC).
Do the totals include land?
Only if you switch on the "include land" toggle. Land varies enormously by suburb, so the default view is build cost only (base build, site costs and statutory fees). The land figure shown is an indicative outer growth-corridor block and should be treated as a rough guide.
