Concrete Swimming Pool Cost, Stage by Stage

Name: comparepoolquotes
Price range: $$$

A concrete swimming pool costs $65,000 to $110,000 installed in Australia, or about $1,800 to $2,300 per square metre of shell, built on site over 12 to 16 weeks. You pay it in stages: the deposit is capped at 5% of the contract price in Queensland and Victoria once the price passes $20,000.

The short answer

$65,000–$110,000 installed, or $1,800–$2,300 per square metre of shell — the per-square-metre figure is the more useful one if your pool is not a standard 7m × 3m.
12–16 weeks of construction, after 3–10 weeks of council approval. A concrete shell is built in place, which is why it takes four times as long as a fibreglass drop-in.
Your deposit is capped by statute. Queensland and Victoria: 5% once the contract is $20,000 or more, 10% below that. New South Wales: 10% of the contract price.
Queensland caps progress claims too — no more than 50% of the contract price including the deposit until at least 50% of the on-site work is complete.
The shell is roughly half the project. Excavation $8,000–$35,000, paving and coping $8,000–$45,000 and the barrier at $80–$600 a metre are quoted separately and are where budgets break.

The six stages of a concrete pool, and what must exist on site before you pay for one
Stage	What happens	What must be true before you pay	Typical share of the build
Deposit	Contract signed, engineering and approvals commissioned	You hold a signed written contract and, where required, the builder's insurance certificate for your property. Do not pay a deposit before the certificate exists	5% in QLD and VIC over $20,000; up to 10% in NSW
Excavation	The hole is dug, spoil carted off, the site is set out to the engineer's plan	The hole is dug to the set-out and the spoil is gone. Rock, if found, is a variation approved in writing before the breaker starts, at the rate in your contract	Small — this is a stage payment, not the excavation cost
Steel and formwork	Reinforcement fixed, plumbing and hydraulics roughed in, penetrations set	Steel is fixed and inspected. Once shotcrete goes on, nobody can see this stage again	Roughly with excavation, as one early claim on many contracts
Shotcrete or concrete shell	The shell is sprayed or poured and cured	The shell exists, is cured and holds its shape. This is the largest single physical milestone in the job	The biggest stage payment on most contracts
Interior finish, tiling and coping	Waterproofing, pebblecrete or tile, coping laid, equipment installed	The interior finish is complete and the coping is laid. A shell without a finish cannot be filled	Substantial
Handover	Pool filled, equipment commissioned, barrier certified	The barrier is certified and, in Queensland, the certifier's final inspection certificate is issued. The pool may not be filled above 300mm before that inspection	Final balance — never pay it before the barrier passes
Victoria's prescribed stages, for comparison	Base 10%, frame 15%, lock-up 35%, fixing 25%	Consumer Affairs Victoria's standard schedule for full construction. A pool contract will differ, but the principle — a named stage, a fixed percentage — is the one to insist on	85% before final

Why the price arrives in instalments, and why that protects you

A fibreglass pool is a manufactured product delivered to your block. A concrete pool is a construction project run in your backyard over 12 to 16 weeks, and it is priced and paid like one. That is not a disadvantage. A staged payment schedule is the single strongest consumer protection in a pool contract, because at every point in the build the money you have paid should be behind the work that exists. When a builder fails, the amount you lose is the gap between those two numbers.

Queensland puts that principle in the rules. For contracts over $3,300, all progress payments must be relative to the amount of work completed, and the contractor cannot claim more than 50% of the contract price — deposit included — until at least 50% of the on-site work is done. Victoria takes the other route and prescribes the stages themselves: base 10%, frame 15%, lock-up 35%, fixing 25%. A pool does not have a frame or a lock-up, so the percentages do not transfer, but the structure does.

The test for any pool payment schedule is simple: could you point at something in your backyard that is worth what you have paid? If not, the schedule is front-loaded.

What the deposit may legally be

This is the one number in a pool contract that is set by law rather than by negotiation, and it is routinely got wrong in industry commentary — including for New South Wales, where the two states either side of it have a different rule.

New South Wales: the maximum deposit is 10% of the contract price, per NSW Government guidance for people building a pool. A written contract is required where the price is over $5,000, the person doing the work must hold a licence over $5,000, and home building compensation cover is required over $20,000 — before the builder asks for or takes any money.
Queensland: 20% for work valued at $3,300 or less; 10% from $3,301 to $19,999 (level 1); 5% at $20,000 or more (level 2). Up to 20% is allowed only where substantial customised work is prefabricated off site and exceeds half the contract price.
Victoria: 10% under $20,000, 5% at $20,000 or more. Do not pay it until the builder gives you a certificate of currency for your property.

Every concrete pool contract in Australia clears $20,000, so in practice the deposit is 5% in Queensland and Victoria and up to 10% in New South Wales. On an $87,500 pool that is $4,375 or $8,750 — a $4,375 difference driven entirely by which side of a state border you are on. Our deposit limits and progress payments guide sets out the rules in full, including what happens if a builder asks for more.

What is not in the shell price

The $65,000–$110,000 range covers the pool. Using a national cost guide dated September 2026, here is what sits outside it, and all of it has to be paid by someone:

Excavation and site access: $8,000–$35,000. The spread is access, spoil volume and cart-out distance. Rock is separate again.
Paving, coping and surrounds: $8,000–$45,000. Often the largest single item after the shell, and the one most often deferred to "stage two" to make a quote look competitive.
Retaining on a sloped site: $5,000–$45,000.
The barrier: $80–$150 a metre for aluminium, $350–$600 for glass. It is not optional and it is not a landscaping choice — see what a pool fence costs.
Heating: $3,000–$14,000, plus running cost forever after.
Council and certifier fees, which are small but real. In Mackay, for example, the swimming pool backwash plumbing application alone is $508.

Add the low end of those and a $65,000 concrete pool is a $90,000 project. Add the high end and it is well past $200,000. That is why two quotes for "the same pool" can differ by $30,000 — they are not quoting the same scope. What should be in a pool quote is the line-by-line version of this list.

The rock clause, and why it decides your final price

Rock and unusual soil conditions are excluded from a standard installed pool price, and excavation is where a quote most often blows out. The difference between a contract that handles this well and one that does not is a single clause.

A good clause states a rate. A dollar figure per cubic metre of rock, or per hour of breaker time, agreed before anyone digs, plus a process: rock is found, the variation is quantified against the rate, you approve it in writing, work continues.

A bad clause says "rock to be quoted on the day". That is not a lower price. It is an unpriced risk sitting on your side of the contract, discovered at the moment you have the least leverage — a hole in your backyard and a machine on hire.

A quote that says nothing about ground conditions on a site with no soil report is not cheaper than one that prices the risk. It has simply moved the risk to you without telling you.

Ask for the rate before you sign, and ask whether a soil report has been done. If the answer is no on both, that is the cheapest question you will ever ask.

Common questions

Can a pool builder ask for more than the legal deposit?

They can ask; they cannot lawfully require it. In Queensland the deposit limits are set in the QBCC Act and the regulator states them plainly — 20% at or under $3,300, 10% for level 1 contracts and 5% for level 2 contracts of $20,000 or more. In Victoria, if a builder does not comply with the deposit rules the building owner may avoid the contract at any time before it is completed.

Is $1,800 to $2,300 per square metre the whole cost?

No — it is the shell rate. A 7m × 3m pool is 21 square metres, so $37,800 to $48,300 of shell, which is why the delivered range starts around $65,000 once excavation, equipment and finish are added. Use the per-square-metre figure to sanity-check a shell price, not to budget the project.

Should I pay the final balance at handover or after the barrier is certified?

After. The barrier is the last thing that can fail and the one thing you cannot use the pool without. In Queensland the pool must not be filled to a depth of 300mm or more until the certifier has inspected the barrier and issued a final inspection certificate, so a pool that is full is a pool that has passed — and a pool that cannot be filled is not finished, whatever the invoice says.

How long does a concrete pool take compared with fibreglass?

A concrete pool takes 12–16 weeks of construction; a fibreglass shell is installed in 2–4 weeks. Both sit behind the same 3–10 weeks of council approval. Our build timeline guide covers the sequence and why a pool build slips covers what goes wrong.
