A winter pool cover in Australia isn't about shutting the pool down. It's about keeping leaves out, slowing evaporation and cutting back on cleaning and chemicals from June to August. At Aussie UnderCover, our family-owned business has been making hidden pool cover systems in Nowra NSW since 2008, and we see plenty of pool owners weighing up leaf nets against pool blankets each autumn. Here's how the two compare, and how to look after your pool through the cooler months.
Key Takeaways
- Most Australian pools don't need to be "closed" for winter, but a cover makes cool-season care much easier.
- Leaf nets and mesh debris covers catch leaves above the water. Pool blankets float on the water to slow evaporation and hold warmth.
- Leaf and debris covers suit heavily treed blocks and pools left unused for long stretches. Blankets on a roller suit pools that still get the odd winter swim.
- No winter pool cover replaces compliant pool fencing, regular water testing or filtration.
- Aussie UnderCover makes hidden roller systems for solar, foam and non-heating blankets. We don't sell leaf nets or mesh covers.
Do You Really Need a Winter Pool Cover in Australia?
You don't need a winter pool cover in most of Australia, but one can save a lot of cleaning, water and chemicals through the cooler months. Unlike colder countries, where pools are drained and closed for months, Australian pools usually keep running all year. On mild days along the NSW coast, in South East Queensland and in Perth, a winter swim is often still on the cards.
A winter pool cover is most worthwhile when:
- Your pool sits under trees that drop leaves, bark and blossom through autumn and winter
- You live somewhere cooler, such as Melbourne, Adelaide, Canberra or the Southern Highlands, where the pool goes unused for months
- You travel, or simply don't use the pool much between June and August
Algae doesn't stop growing just because the weather cools, so some cover combined with basic circulation and sanitation is useful year round. A cover also means less work to get the pool swim-ready again in spring.
Types of Winter Pool Covers: Leaf Nets, Mesh Debris Covers and Pool Blankets
"Winter pool cover" can mean two very different things in Australia: a leaf or debris cover stretched over the pool, or a pool blanket floating on the water.
Leaf nets and debris covers: A net or mesh cover stretched across the pool and anchored around the edge to catch leaves before they reach the water. Mesh lets rain drain through, while solid tarp-style covers block more debris but can hold water on top.
Pool blankets: A blanket floats directly on the water. A solar blanket lets sunlight through to warm the water, a foam blanket insulates heated pools, and a non-heating cover controls evaporation without adding warmth. Blankets keep dust, insects and leaves off the water while they're on, but they're not built to catch heavy leaf fall the way a stretched net is.
Aussie UnderCover doesn't sell leaf nets or mesh covers. We design and make hidden inground roller systems for pool blankets.
Pros and Cons of Leaf and Debris Covers in Australian Backyards
Leaf and debris covers are good at one job: stopping large amounts of leaves from landing in the pool. That makes them a common choice when autumn leaf fall turns a pool green.
Advantages:
- Strong protection from leaf fall, with less skimming and vacuuming
- Useful for pools under heavy tree canopy
- Mesh designs let rainwater drain through rather than pooling on top
Drawbacks:
- They take more effort to put on and take off than a blanket on a roller, and can be heavy and awkward when wet
- Anchors and straps around the edge can be a trip hazard if not secured properly
- While installed, they make a casual winter dip impractical
- Fine particles can still pass through mesh and settle on the pool floor
Leaf nets and debris covers are not safety covers. They must never be relied on to support a person or pet, and they never replace compliant pool fencing.
Debris covers work best for holiday homes that sit empty through winter, or for heavily treed properties with relentless leaf fall. For a suburban pool where someone still wants a swim on a sunny July afternoon, a pool blanket on a hidden roller is usually easier to live with.
How Pool Blankets Help Through Winter: More Than Just a Summer Accessory
A pool blanket keeps working through winter. Many people think of blankets as summer gear, but they help most when the pool isn't being used much.
- Less evaporation. Dry, windy winter days still draw water off an uncovered pool. A blanket on the surface keeps more of it in, so you top up less often.
- Fewer chemicals. With less sun on the water and less fresh top-up water diluting the balance, sanitiser lasts longer. Consistent cover use can help cut chemical costs by up to 50%.
- Warmer water. A solar blanket gains warmth on sunny days and a foam blanket holds heat in a heated pool, so the water is less of a shock on a winter swim. Consistent use can help cut heating costs by up to 70%.
- A cleaner pool. Leaves and dust land on the blanket rather than sinking, which makes them easier to clear.
If you're not sure which blanket suits your pool, our guide to choosing between solar, foam and non-heating pool blankets walks through each option.
Looking After Your Pool in Winter: Simple Monthly Routine
Winter pool care in Australia is simple, and a pool cover means each visit takes less time. A light monthly routine keeps the water healthy until spring.
- Water level: keep it at the skimmer opening so the equipment works properly.
- Water balance: test and adjust pH, alkalinity and sanitiser. Cold water slows chemical reactions but doesn't stop them.
- Brushing: give the walls and floor a quick brush so sediment doesn't settle and stain.
- Circulation: run the pump on a shorter daily cycle, but don't switch it off.
If you use a leaf or debris cover: pull it back now and then to vacuum fine material and check for early algae. After heavy rain, clear water sitting on a solid cover before it sags.
If you use a pool blanket: roll it fully off every week or two, hose dirt and leaves off the blanket, check the water and look over the edges for wear before winding it back on.
A cover is an aid, not a reason to stop testing. Water that's out of balance in August can mean staining or scale by spring.
Hidden Inground Pool Cover Systems vs Exposed Rollers and Nets
A hidden inground pool cover system stores your blanket in a pit beside the pool, under a lid that sits flush with your tiles, pavers, concrete or decking. There's no roller frame on the coping and no net anchored around the edge.
An above-ground roller takes up deck space and sits out in the weather year round. A leaf net adds clutter and can be a two-person job to remove. A hidden system keeps the pool surround clear, and covering the pool takes moments, so the blanket actually gets used through autumn, winter and spring.
Aussie UnderCover systems work with solar, foam and non-heating blankets, in manual or remote-controlled semi-automatic versions. Blankets can be cut to suit shaped pools, so kidney and freeform designs are covered too. Compare blanket materials on our pool cover options page.
Choosing the Right Winter Pool Cover Strategy for Your Swimming Pool
Many pool owners end up with a winter strategy rather than a single product. Here's how it often plays out:
- Heavy leaf fall from large trees: a debris cover during peak leaf drop, with a blanket for everyday use the rest of the year.
- Open, sunny backyard: a solar or foam blanket on a hidden roller, with little need for a debris cover.
- Heated pool: a foam blanket to hold heat overnight.
- Holiday home visited rarely: a debris cover for long absences, or a blanket if someone checks the pool each week.
- Kidney or freeform pool: a blanket cut to the pool's shape on a hidden roller. Debris covers also need careful measuring to avoid gaps.
If you want to swim on the odd warm winter day, a blanket you can roll back in seconds beats a net that has to be unclipped around the edge. If you won't swim until October and leaf fall is the main problem, a debris cover may be the better fit. Whatever you choose, it must sit behind compliant pool fencing.

Frequently Asked Questions About Winter Pool Covers in Australia
Can I completely switch my pool off over winter if I use a cover?
No. Even with a cover on, keep the pump and sanitation running. Algae can take hold in still, untreated water whatever the temperature. Run the pump on a shorter cycle and keep basic chlorination going. A cover reduces the load on your sanitiser but doesn't replace filtration.
Is a winter pool cover safe for kids and pets to walk on?
No. Leaf nets, debris covers and solar, foam and non-heating blankets are not safety covers and must never be walked on. Compliant pool fencing and active supervision remain essential around any pool, covered or not.
Do winter leaf and debris covers suit shaped pools like kidneys or freeform designs?
They can, but they need careful measuring and are usually custom made, because a generic rectangle leaves gaps along curved edges. Pool blankets for our hidden systems can also be cut to suit shaped pools so they sit neatly on the water.
How often should I remove my pool blanket during winter?
Roll it fully off every week or two. That gives you a chance to check the water, brush the walls, test the chemistry and hose dirt off the blanket. With a hidden roller, it only takes a moment.
Will a solar pool cover make my pool too warm in summer if I install it mainly for winter benefits?
In hot regions or very sunny backyards, a solar blanket can add more warmth than you want in midsummer. You can leave it off during the hottest weeks, or choose a non-heating cover instead. Call Aussie UnderCover on 1300 722 009 and we'll help you choose the blanket that suits your climate.
