The best swimwear Australia has for beach, pool and surf
Eight picks — every fabric percentage, size range and rating below is quoted from the brand’s own page, and every gap is flagged honestly.
1. Seafolly Collective Boyleg One Piece
80% recycled nylon / 20% elastane, fully lined, with an internal shelf bra, soft cups and gripper tape to hold the suit in place — AU 6–18, rated 4.9/5 from 60 reviews on Seafolly AU.
This is the coverage-and-confidence formula from Seafolly Australia: a boyleg legline, hidden support and a suit that stays put. Seafolly’s own fit guidance: true to size, or go up a size for a relaxed fit and fuller coverage. It’s the best swimwear Australia pick for beach and resort days. One limit: no chlorine-resistance claim is made — daily lap swimmers should take the Speedo below.
- Hidden support that actually stays in place
- Strong owner ratings (brand site)
- Full-coverage boyleg cut
- Boyleg cut is the opposite of high-leg fashion
- Not positioned as a chlorine training suit
2. Seafolly Collective Wrap Front F Cup Bikini Set
Underwire F-cup top with convertible straps and an adjustable E-hook (4.9/5 from 28 reviews) plus a high-waisted full-coverage bottom (4.9/5 from 53) — both 80% recycled nylon / 20% elastane, fully lined, AU 6–18.
Most bikinis fail fuller busts; this one is built for them — real underwire, hidden mesh, and straps that convert. Buying as separates means your top and bottom sizes are independent decisions, which is how bikini sizing should work. The trade-offs: two purchases instead of one, and the bottom is deliberately full-coverage, not cheeky.
- Genuine underwire support in a bikini
- Independent top/bottom sizing
- Top-rated by owners on Seafolly AU
- Separates = two size decisions
- Full-coverage bottom, not a high-leg look
3. Speedo Endurance+ Medalist
Endurance+ fabric — 53% recycled polyester / 47% PBT — with Speedo’s listed claim of “100% chlorine resistance” and quick dry; fully lined, medium leg. Rated 4.6 from 365 reviews on Speedo AU.
The workhorse pick. Speedo positions Endurance+ for regular chlorine swimming and advises a fresh-water rinse after use; the Medalist back is cut for shoulder movement in training. Note the exact fabric name — the AU page lists “Endurance+” (not “ECO Endurance+”), and one of its yarns is made from post-consumer waste. The feel is firmer than high-elastane fashion swim — that’s the durability trade.
- Built for daily chlorinated training
- Huge owner review base (Speedo AU)
- Widest size guide in this list
- Functional cut, not fashion styling
- Firmer fit than fashion swim fabrics
4. Artesands Delacroix One Piece
Wire-free multifit cups for D–G, 360-degree powermesh internal structure, front ruching and wide straps — in Australian sizes 12–28.
Artesands calls the Delacroix its best-selling curve-fit one-piece, and the structure explains why: powermesh through the whole body, soft cups and straps that don’t dig. Two honest notes: Artesands’ own pages didn’t publish a fabric percentage for this one-piece in our research (we won’t invent one), and the shape is a beach/holiday suit — for heavy chlorinated training, the Speedo is the pick.
- Real AU 12–28 curve range
- Multifit D–G cups — no exact cup guessing
- Powermesh smoothing structure
- Fabric % not published on brand pages checked
- Not a heavy-chlorine training suit
5. Sunseeker Japan DD–E Soft Strap One Piece
A minimiser fit with hidden underwire and powermesh cup, underbust and front support — outer 85% recycled Repreve® nylon / 15% elastane, recycled lining, sizes to AU 18.
Where Artesands goes multifit, Sunseeker goes precise: cup-specific DD–E fitting with hidden underwire for shoppers who want exact support. The boundary is size — the chart stops at AU 18, so beyond that, Artesands’ 12–28 range is the verified route.
- Precise DD–E cup fitting
- Hidden underwire + powermesh support
- Recycled fabrics inside and out
- Chart stops at AU 18
- Cup-specific fit is less forgiving than multifit
6. Rip Curl Amare L/S UPF Surfsuit
Long-sleeve one-piece with front zip, fully lined — listed by a surf retailer as Microfibre Lycra® Extra Life™, 86% polyamide / 14% elastane, UPF 50+.
The coverage pick for surf and paddle: sleeves and torso covered, zip entry, nothing to come loose in a wipeout. Full transparency on sourcing: the UPF 50+ rating and fabric split come from a retailer listing for this style — Rip Curl’s own pages we opened did not state them, and Australian availability of this exact style needs a live check. Verify the UPF on the AU listing before buying on that claim.
- Full arm + torso sun coverage
- Stays put in surf
- Front-zip easy entry
- UPF/composition from retailer listing — verify on AU page
- Maximum coverage = maximum tan lines avoided, not made
7. Ripe Maternity Ultimate One Piece
Purpose-cut maternity suit in chlorine-resistant stretch polyester (100% polyester as listed): tummy gathers, adjustable straps with optional cross-over, removable cups. XS–XXL = AU 8–18.
Ripe designs this suit to “take you through all the stages of pregnancy” — and for pool swimmers, the chlorine-resistant polyester is the practical headline. Honest notes from the brand’s own page: it is explicitly non-nursing (no feeding access after birth), and its page rating is 3.0/5 from just 2 reviews — too small a sample to judge by, so judge by the design instead.
- Purpose-cut for a changing bump
- Chlorine-resistant for regular pool use
- Cross-over strap option
- Explicitly non-nursing
- Very small review sample on the brand page
8. Cotton On Recycled Swim Separates
Fully lined separates made with recycled polyester — including a gathered Brazilian bottom with published measurements from 3XS to 5XL, and a high-waisted option.
The budget floor of our best swimwear Australia list, and a genuinely wide size run. The honest limits: Cotton On’s pages didn’t publish a fabric percentage or UPF for these women’s styles in our research, and Brazilian coverage is minimal by design — for support features (underwire, powermesh, shelf bras), step up to the Seafolly and Artesands picks.
- Widest budget size run (3XS–5XL)
- Fully lined, recycled fabric
- High-waist option in range
- No % composition or UPF published on pages checked
- Brazilian coverage is minimal
Swimwear buying notes: chlorine, UPF honesty and sizing
Chlorine eats elastane. That’s why the training pick is a polyester/PBT blend (Speedo Endurance+, listed as 100% chlorine resistant) while fashion suits are nylon/elastane. Whatever you buy, follow Seafolly’s care rule: rinse after use, wash cold and gentle, dry in shade.
The UPF truth: of every brand page our research opened, only ONE style — a retailer listing for the Rip Curl Amare surfsuit — stated a UPF rating (50+). Seafolly, Speedo, Artesands and Sunseeker pages stated none. So never assume a swimsuit is sun-protective: if UPF matters, buy a style whose AU product page states it, and cover the rest with shade and sunscreen.
Sizing: AU swim ladders differ wildly — Seafolly 6–18, Artesands 12–28, Sunseeker to 18, Cotton On 3XS–5XL, and Speedo’s guide spans AU 2–24. Use each brand’s centimetre chart. Complete the kit with our Sandals and Summer Dress guides.
Swimwear questions, answered
What is the best swimwear in Australia in 2026?
The Seafolly Collective Boyleg One Piece is our best overall — 80% recycled nylon, a shelf bra with gripper tape, and a 4.9/5 rating from 60 reviews on Seafolly Australia. For lap training, the Speedo Endurance+ Medalist; for curve sizes AU 12–28, the Artesands Delacroix. All lead our best swimwear Australia rankings. That breadth is what makes this the best swimwear australia round-up for 2026.
What swimwear lasts longest in chlorine?
Polyester-based training suits. Speedo’s Endurance+ Medalist (53% recycled polyester / 47% PBT) is listed by Speedo as 100% chlorine resistant and quick dry, and rated 4.6 from 365 reviews on Speedo AU. Whatever you wear, rinse in fresh cold water after every swim. For daily laps, the best swimwear australia pools see most is a polyester training suit like this one.
Does swimwear protect against UV with a UPF rating?
Only if the product page states it. Of all the brand pages our research opened, only a retailer listing for the Rip Curl Amare surfsuit stated UPF 50+; Seafolly, Speedo, Artesands and Sunseeker stated no UPF at all. Never assume — check the specific style’s AU listing, and cover up with shade and sunscreen. For surf days, the best swimwear australia shoppers pick for sun coverage is a long-sleeve surfsuit like the Rip Curl Amare.
What is the best swimwear for a bigger bust?
Seafolly’s Wrap Front F Cup bikini top has real underwire and convertible straps (4.9/5 from 28 reviews); Sunseeker’s Japan DD–E has hidden underwire and powermesh support; and Artesands’ Delacroix fits D–G cups in sizes AU 12–28 without wire. All three are in our guide. For a bigger bust, the best swimwear australia shoppers keep coming back to combines real support with comfortable straps.
How do I choose my swimwear size?
By centimetres, not by the AU number — ladders differ: Seafolly runs AU 6–18, Artesands 12–28, Cotton On 3XS–5XL and Speedo’s guide spans AU 2–24. Seafolly’s own guidance is to size up if you prefer a relaxed fit or fuller coverage. Measure in centimetres first — the best swimwear australia size charts reward a tape measure over a guessed AU number.
Is recycled swimwear fabric good quality?
Yes — the top picks in our guide use it: Seafolly’s suits are 80% recycled nylon, Sunseeker uses recycled Repreve nylon, and Speedo’s Endurance+ yarn is partly post-consumer waste. Support comes from construction — lining, shelf bras, powermesh — not from virgin fibres. Recycled fabric is now standard across the best swimwear australia picks in this guide. Shoppers who want recycled fibres no longer have to compromise — the best swimwear australia brands now build them into everyday styles.
