Pool Finance in Queensland: Loans, Payment Plans and the 5% Deposit Rule

Most Queensland homeowners who finance a pool use one of three routes: they add it to the home loan (a top-up, redraw or refinance), they take an unsecured personal or pool loan, or they use a payment plan from a lender the builder works with. The home loan usually carries the lowest rate, but the loan term decides the total cost far more than the rate does. And because Queensland law caps a pool builder's deposit at 5% on any contract of $20,000 or more, you do not need the whole amount on the day you sign.

This is general information from a pool builder, not credit or financial advice. Wahoo Pool & Landscape Construction is not a credit provider, credit assistant or broker. Talk to a licensed lender or broker about your own situation.

Start with the full amount you need to borrow

The package price is the starting figure, not the finished one. Our twelve turnkey concrete packages currently start from $38,900 for the 5 × 3 m plunge pool and run to $64,300 for the 10 × 4 m Grand Pool, or $76,690 with the integrated spa (prices read from our catalogue on 14 October 2026; the package pages always show the current figure).

Around the pool sits the work that depends on your block, and it needs funding too:

• Pool safety fencing. We coordinate it and itemise it separately. Under the Queensland pool fencing rules the pool cannot be filled until the barrier is certified, so it is not optional spending.
• Retaining walls, extended paving, decking and landscaping. These are quoted after the on-site assessment because they change from one yard to the next.
• Site conditions. Rock, slope and access can add cost. Our article on hidden costs in pool quotes lists what to look for.

Borrow against an itemised quote rather than a brochure price, and leave headroom. Variations happen, and the first years of ownership have their own costs, which we set out in the first ten years of running a pool. Taking the maximum a lender will approve leaves nothing for either.

The main ways to pay for a pool

Route	How it works	Usually suits	Check before you commit
Home loan top-up, redraw or refinance	The pool is funded from your mortgage, secured against the house.	Owners with equity who want the lowest rate on offer.	Approval and possibly a valuation take time. Spread over the remaining mortgage term, interest adds up fast (see the table below).
Unsecured personal or pool loan	A separate loan, usually over one to seven years, with no security over the house.	Owners who would rather not touch the mortgage, or who have little equity.	Unsecured loans usually carry higher rates. Compare the comparison rate, fees and any early repayment fee.
Payment plan through the builder's finance partner	A loan from a third-party lender the builder refers you to. The lender assesses and approves it, not the builder.	People who want one application tied to the build.	It is still a personal loan. Read the lender's terms, fees and comparison rate like any other loan.
Savings	You pay each stage from cash.	Anyone who can do it and still keep an emergency buffer.	Do not empty the buffer. A storm repair or a failed pump in year five still needs paying for.

You can also combine routes, for example savings for the deposit and early stages and a loan for the rest.

Why the loan term matters more than the rate

Take $50,000 as a round figure and compare two rates over four terms. These are standard principal-and-interest repayments before fees, worked out for this article. The 6% and 10% rates are illustrations to show the arithmetic, not current market rates or offers.

Term	At 6% p.a.: monthly	At 6% p.a.: total interest	At 10% p.a.: monthly	At 10% p.a.: total interest
5 years	$967	$8,000	$1,062	$13,700
7 years	$730	$11,400	$830	$19,700
10 years	$555	$16,600	$661	$29,300
25 years	$322	$46,600	$454	$86,300

Put $50,000 on a 25-year mortgage at 6% and you pay about $46,600 in interest. The same $50,000 at 10% over seven years costs about $19,700. The mortgage rate is lower, but stretching a pool across the rest of the home loan is what makes it expensive.

If you use the mortgage, ask your lender whether you can split the pool amount into its own loan account and repay it over five to seven years, or plan to pay extra each month. If you use a personal loan, the shortest term you can comfortably afford keeps the total down. Either way, compare loans on the comparison rate, which Moneysmart describes as a guide to the true cost because it includes interest and most fees.

How a Queensland pool builder is allowed to bill you

A pool build is domestic building work, and the QBCC sets the rules on deposits and progress payments. They shape how much money you need, and when.

• Deposit cap. For contracts of $20,000 or more, the maximum deposit is 5% of the contract price. Under $20,000 it is 10%. A higher deposit of up to 20% is only allowed where more than half the contract value is work done off-site, which does not describe an in-ground concrete pool. Every one of our packages is above $20,000, so on the $46,400 Family Pool I the deposit can be no more than $2,320.
• Progress payments follow the work. The number and timing of payments are agreed in the contract, but each one must be relative to the work completed. The QBCC's own example: a contractor cannot claim more than 50% of the price, deposit included, until at least half the work on site is done.
• Do not pay early. The QBCC warns that paying more than the legal deposit, or paying ahead of the contract schedule, reduces the protection you have under the Queensland Home Warranty Scheme.

Our standard milestones are the deposit, excavation, shell spray, finishes and handover, and your contract sets the amount due at each one. The $500 site assessment deposit comes before any of this. It books the on-site visit and itemised quote, it is refunded in full if you decide not to go ahead, and it is credited to your contract if you do.

Staged billing affects which loan works best. A personal loan usually pays out as a lump sum, so interest starts on the full amount from day one while the builder can only claim it stage by stage. At a 10% rate, every month that $50,000 sits waiting costs about $417. Ask whether your lender can release funds in stages. If the money has to land in one go, ask whether it can sit somewhere that reduces the interest, such as an offset account if your home loan has one. A redraw or top-up lets you pay each claim as it arrives.

Get the finance answer before you sign

For a contract over $3,300, Queensland law gives you a cooling-off period of five business days. It starts the day after you receive a signed copy of the whole contract, including plans and specifications, and for contracts of $20,000 or more, a copy of the QBCC Consumer Building Guide. To withdraw, you give the builder a signed written notice under section 35 of Schedule 1B of the QBCC Act, and the builder can keep $100 plus reasonable out-of-pocket expenses. You cannot use the cooling-off period if you had formal legal advice on the contract before you signed it.

Five business days is not long enough to get a loan approved from scratch. Get your lender's answer, or at least a pre-approval, before you sign. If your contract is unusual or the finance has conditions attached, get legal advice on the contract before you sign.

"Interest-free" and "swim now, pay later" offers

Search for pool finance in Brisbane and much of what comes up is "swim now, pay later" pages from pool companies. Some are ordinary loans with a friendly name; some are interest-free promotions. Moneysmart's guidance on interest-free deals is direct: interest-free does not mean cost-free. Before you sign up, check:

• the fees: establishment, account keeping, annual card fees and late fees can apply during the interest-free period;
• how the repayments are set: minimum repayments may not clear the balance before the promotion ends;
• the rate that applies afterwards: Moneysmart notes it can be as high as 29% on any balance still owing;
• the total you will repay, including every fee.

Ask any builder for the cash price and the financed price in writing. If they differ, the difference is part of what the finance costs you.

How finance works with Wahoo

We build pools; we do not lend money or arrange credit. Owners who want a payment plan can apply to Handypay (OurMoneyMarket Lending Pty Ltd, Australian Credit Licence 488228), which assesses the application, approves the credit and manages the repayments. We do not see your application. The current rates, fees, loan limits and Handypay's own disclosures are on our pool finance page, and any question about the loan itself goes to Handypay.

The figure your lender needs is the total you are borrowing. Our packages are fixed-price with itemised inclusions, and the site assessment adds an itemised quote for everything outside the package, so you have that total before you apply. Whichever route you choose, our invoices follow the contract milestones above.

A short checklist before you apply

• Get an itemised quote that covers the pool, fencing, and any retaining, paving and landscaping.
• Decide the loan term on purpose, not by default.
• Compare loans on the comparison rate and on the total repaid.
• Check the contract deposit is no more than 5% and that each payment matches a stage of work.
• Have the finance approved, or pre-approved, before you sign.
• Check the builder's licence on the QBCC register. Ours is 15247996, and this guide shows how to check any builder.

Frequently asked questions

How much deposit can a pool builder ask for in Queensland?

For a contract of $20,000 or more, no more than 5% of the contract price. For contracts under $20,000 the cap is 10%. The only exception, up to 20%, is where more than half the contract value is work done off-site. Source: the QBCC.

Is it cheaper to put a pool on my mortgage?

The rate is usually lower, but the total cost depends on how long you take to repay it. $50,000 at 6% over 25 years costs about $46,600 in interest; over seven years it costs about $11,400. Ask your lender about splitting the pool amount and repaying it faster.

Can a pool loan cover fencing and landscaping?

A mortgage top-up or personal loan pays out money you can put towards any part of the project. The Handypay plan we refer owners to can also cover the work we quote separately, such as retaining walls, paving, decking and fencing. Check the current terms on our pool finance page.

Does Wahoo offer pool finance?

Not directly. We are a QBCC-licensed pool builder, not a lender or broker. Owners who want a payment plan can apply to Handypay, which makes its own credit decision.

Can I pull out if my finance falls through after I sign?

Within the five-business-day cooling-off period you generally can, by giving written notice and paying $100 plus reasonable out-of-pocket costs. After that it depends on your contract, so get the finance answer first and take legal advice if you are unsure.

Do I have to pay for the pool before it is finished?

No. After the deposit, each progress payment must match the work completed on site, and the QBCC advises against paying ahead of the contract schedule.

Get the figure your lender will ask for

Book a $500 refundable site assessment and we will measure the block and give you an itemised fixed-price quote for the pool and the work around it. That quote is what you take to your lender. If you want to talk it through first, call 1300 924 666 or request a quote online.
