Two methods, two outcomes
Partial removal breaks out the top of the shell — usually the first 500mm or so — punches holes through the base so water can drain rather than pool inside the void, and backfills the remainder. It is faster, cheaper, and produces less spoil to cart away.
Full removal takes out the entire shell, the base and the surrounding material, then backfills in compacted layers with certified fill and documents the compaction.
The price difference is significant, and so is the difference in what you own afterwards.
Why the method matters more than the price
A partially removed pool leaves a substantial volume of uncertified fill in your back yard. That has three consequences worth understanding before you choose the cheaper option.
You cannot build over it. Not practically. A builder or certifier will not accept structural load over ground that has not been engineered and documented. If there is any chance of an extension, a granny flat, a shed slab or a pool of your own further down the track in that part of the block, partial removal closes it off.
It can settle. Uncertified fill continues to consolidate. A lawn over a partial fill can develop a shallow depression over the following years, and re-levelling it is your problem.
You have to disclose it. A filled pool is a material fact about a property. It comes up at sale, and a buyer's building inspector will find it.
None of this means partial removal is wrong. If the area will remain lawn or garden, the block is large, and nothing structural is ever going near it, partial removal is a perfectly sensible use of money. It just needs to be a decision made with the trade-off visible.
Access decides the rest
After the method, access is the biggest variable in an Illawarra pool removal. Most pools are in back yards, and getting an excavator into a back yard means a side gate wide enough, a path capable of taking the machine, and somewhere for the spoil to go.
The older suburbs along the escarpment — Thirroul, Bulli, Corrimal, Woonona — and the tighter parts of Wollongong and Port Kembla frequently have narrow side access, sometimes under 900mm. That may mean smaller machines, more passes, or in difficult cases craning a machine over the house, which is a different order of cost.
Newer estates through Dapto, Shell Cove and Shellharbour usually have straightforward side access.
We look at the access before quoting, because it is the thing most likely to make a phone estimate wrong.
Fibreglass versus concrete
A fibreglass shell is lighter and comes out more easily, often in large sections, which reduces both machine time and disposal weight. A concrete shell is broken up in place, and reinforced concrete needs a hammer rather than a bucket — see concrete removal for how that work is priced.
Either way the plumbing, the pump, the filtration and the fencing should be in the scope. Confirm it in writing.
Water, and when to do it
Two practical points that affect scheduling.
The pool has to be emptied, and the water has to go somewhere. Discharging a pool is subject to council and water authority requirements — chlorinated or salt water released into a stormwater system or across a neighbouring property causes problems. Controlled discharge to sewer, or dechlorination first, is usually the correct route. Check what your council requires rather than pulling the plug and hoping.
Timing matters more than for most demolition. Pool removal is excavation work, and excavation in wet ground is slower, messier and considerably harder on the surrounding lawn and paving. Where the schedule is flexible, a drier stretch makes for a cleaner job and less reinstatement afterwards.
Your pool fencing and safety obligations continue to apply until the pool genuinely no longer holds water, so the fence comes out at the end of the job, not the beginning.
What is left behind
A full removal should leave you level ground with certified, compacted fill and the documentation to prove it. A partial should leave you level ground with a clear written record of what remains below and at what depth. Keep that record — you will want it at sale.

Frequently asked questions
What is the difference between a partial and a full pool removal?
A partial removal breaks up the top portion of the shell, punches drainage holes through the base, and backfills. A full removal excavates the entire shell and all the material out of the ground and backfills with certified fill, compacted in layers. Partial is cheaper and faster. Full leaves you land you can build on and a clean disclosure position at sale.
How much does pool removal cost in the Illawarra?
As a 2026 planning guide, a partial removal on an accessible block commonly runs $8,000 to $15,000, and a full dig-out $15,000 to $30,000 or more. Access is the biggest variable after the method — a backyard pool with no side access to get a machine in changes the job substantially.
Can I build over a filled-in pool?
Not over a partial fill, in practical terms. Ground that has been backfilled without engineered compaction and documentation is not something a builder or a certifier will accept structure on. If there is any prospect of building over or near the area — an extension, a granny flat, a slab — the full dig-out with certified, compacted fill is the option that keeps that open.
Do I need approval to remove a pool?
Usually something is required, and it varies by council. Removing a pool typically involves updating the property's records, and the work may fall under an exempt or complying development pathway or need consent depending on the scale of excavation and what else is happening on the site. Pool fencing and safety obligations also apply right up until the pool is genuinely gone.
What about the pool equipment and the fence?
Pumps, filters, heaters, plumbing and the pool fence are normally included in the scope, but confirm it in writing. Leftover pool plumbing running under a lawn is a nuisance to discover later, and a redundant pool fence is an odd thing to be left with. Ask specifically what is being taken.
