Kahuna 8ft x 11ft Rectangular Review (2026)
The rectangular pick — rated to 150kg, with a zip-and-clip entry and an anchor kit in the box for around A$875 — but it is the only trampoline in Kahuna's range with a powder-coated rather than galvanised frame.

Who the Kahuna 8ft x 11ft Rectangular is for
Households with older children, teenagers, or anyone doing anything more deliberate than bouncing. A rectangle delivers more height for the same effort and an even response across the mat, which is why gymnastics uses the shape.
Families with two jumpers who want each of them to have their own end rather than being returned to the middle.
Buyers who want a large trampoline from a brand that is genuinely stocked on Amazon Australia with free delivery, rather than one they have to special-order.
The specification
An 8ft x 11ft rectangular outdoor trampoline with a safety enclosure, listed on Amazon Australia at A$875 with free delivery. We confirmed that on 4 August 2026 with the delivery address set to an Australian postcode.
Maximum user weight 150kg — the top of Kahuna's entire range. Kahuna describe it as "one of our most heavy-duty trampolines" and say the larger frame makes it "great for adults too".
Conventionally sprung, with 76 high-carbon steel springs around the perimeter under a UV-stabilised safety pad. Eight safety poles and eight legs arranged in four pairs, with angled tubes at each corner for stability. The mat is an anti-graze flat-rolled design. Overall height 270cm, mat height 90cm, unit weight 82kg.
The entrance is a zip-and-clip safety lock — a double-secure closure rather than an overlapping flap — and Kahuna state the fine mesh net "prevents adventurous jumpers from making contact with the frame or springs", which describes an inside-mounted enclosure.
A trampoline anchor kit is included, along with a spring tool and a bonus ladder with a hanging mesh compartment for shoes.
The frame is powder-coated steel. Hold that detail — it is the one specification on this page that changes the recommendation, and we come back to it below.
Warranty is one year. Kahuna publish no safety standard for this or any other model in their range.
Kahuna is stocked on Amazon Australia in real depth — a Classic 10ft round at A$611, a Blizzard 14ft at A$789, a 6ft x 9ft rectangular at A$819, an 8ft x 14ft oval at A$892, and 6ft rounds from around A$405 — so if this size is not right, the range is there. Note their own website moved: kahunatrampolines.com.au no longer exists and the live site is kahuna.com.au.
What’s good
The bounce is the whole point. A round mat funnels every jumper back to the centre; a rectangle responds evenly wherever you land, and returns more height for the same effort. If the trampoline is for someone who actually wants to jump rather than to bounce around, this is the shape.
Rectangular options are genuinely scarce in the Australian market, and scarcer still with an ordinary Amazon purchase path. Google's own related searches ask for "best rectangular trampoline Australia" twice over, and almost nothing published here answers it properly.
At A$875 it substantially undercuts the premium brands for a comparable amount of usable mat.
Kahuna's Amazon Australia presence is deep and mostly carries free delivery, which is unglamorous and matters a great deal in November.
Pros
- A rectangular mat gives a more even bounce across the whole surface instead of returning every jumper to the centre, which is why gymnastics uses rectangles — and it means two people can hold their own ends rather than colliding.
- A published maximum user weight of 150kg, which is the top of Kahuna’s entire range and equal to the 16ft Everfit and the 12ft Plum. Kahuna describe it as "one of our most heavy-duty trampolines" and say it is "great for adults too" — on a shape chosen for bounce height, that rating is the number you most want to see.
- The entry is a zip-and-clip safety lock, which closes completely rather than overlapping. That is the same mechanism we credit the Everfit for and the one the Lifespan at rank 7 does not have. The entry point is where enclosures most often leave a gap, and this one is closed by design.
- Kahuna state the fine mesh net "prevents adventurous jumpers from making contact with the frame or springs" — an inside-mounted enclosure, which is the same design virtue that earns the Plum its rank and cannot be retrofitted later.
- A trampoline anchor kit is included in the box, along with a spring tool and a bonus ladder. Anchoring is not optional in an Australian backyard and almost nobody includes it — on our own accessories page an anchor kit is a A$36–46 purchase.
- 76 high-carbon steel springs on 8 poles and 8 legs arranged as 4 pairs, with angled tubes at each corner for stability. Both the safety padding and the net are UV-stabilised, and the mat is an anti-graze flat-rolled design.
- At 8ft x 11ft it is the largest rectangular we found with a Buy Box on Amazon Australia, and rectangular options in this market are thin.
- Kahuna is stocked in genuine depth on Amazon Australia with free delivery on most of the range, so this is an ordinary purchase rather than a special order — which matters more than usual given the state of their own website.
Cons
- Kahuna publishes no safety standard at all, for any trampoline they sell. We searched ten of their product pages, their homepage and five collection pages: no AS 4989:2015, and no ASTM, CE or EN 71 either. Every other brand we have checked directly publishes something. This is not us failing to look.
- This is the one trampoline in Kahuna’s range with a powder-coated frame rather than a galvanised one. Their 8ft, 10ft, 12ft and 14ft Classics and the 8ft x 14ft oval all specify galvanised steel; the rectangular specifies "Powder Coated Steel". Our own buying guide says galvanising is what decides whether a frame survives a decade within reach of the coast, and powder coat over untreated steel rusts from the inside where you cannot see it. You would only ever find this by reading the range side by side.
- The warranty is one year, which is the shortest published term on this page. Jumpflex and Lifespan both give ten years on the frame at a comparable price.
- It is conventionally sprung. If you came to this page for the springless argument, this is not that trampoline — Kahuna do sell a springless "Twister", and it uses wide elastic straps rather than composite rods or leaf springs, but it is not stocked on Amazon Australia so it cannot be this entry.
- A rectangular mat gives the highest, most consistent bounce of any shape. That is a feature for a teenager practising and a genuine risk factor for a five-year-old. Match the shape to who is actually using it.
- Kahuna moved web address and their old domain no longer exists, which is worth knowing before you rely on being able to find warranty terms or spare parts online in year three.
What’s genuinely bad
We nearly published something false about this brand and you should know what it was. Our earlier research had a "Kahuna Twister Springless" in this slot at around A$775, marked as springless. When we checked Amazon Australia on 4 August 2026 with an Australian delivery address set, there is no Twister trampoline there at all — the only "Twister" listing in the entire result set is a roof shade cover. If you specifically want springless at Kahuna money, look at the Lifespan Hyperjump 3 instead.
This is the only trampoline in Kahuna's range with a powder-coated frame instead of a galvanised one, and you would never find that out from this page alone. We read ten of their product pages. The 8ft, 10ft, 12ft and 14ft Classics all specify galvanised steel. The 8ft x 14ft oval specifies galvanised steel. This rectangular specifies "Powder Coated Steel". Powder coat over untreated steel looks identical in a photograph and rusts from the inside of the tube, where you cannot inspect it — which is exactly why our buying guide argues that galvanising is the specification that decides whether a frame outlasts everything bolted to it. If you live within reach of the coast, and most Australians do, weigh that against the 150kg rating before you order.
Kahuna publishes no safety standard at all. Not AS 4989:2015, and not ASTM, CE or EN 71 either — across ten product pages, their homepage and five collection pages. Every other manufacturer we have checked directly publishes something. See the safety section below.
The warranty is one year, which is the shortest published term on this site. Jumpflex and Lifespan Kids both give ten years on the frame at comparable money, and Lifespan add a ten-year guarantee against rust specifically.
This trampoline is conventionally sprung, so the spring pad is the component most exposed to Australian UV and the one that will fail first. Treat it as a consumable.
A rectangular mat is the wrong buy for young children. The higher, more consistent bounce that makes it good for a teenager is exactly what you do not want under a five-year-old still learning to land.
Kahuna changed web address and their old domain no longer resolves. Their live site is kahuna.com.au. On a budget brand that is a reason to buy through Amazon rather than direct — the listing, the returns process and the order record all survive a website migration.
Do not buy a rectangular trampoline for young children. The higher, more even bounce that makes it good for older kids and gymnastics is exactly what you do not want under a five-year-old — buy a round. And if a galvanised frame is what you are shopping for, note that this is the one model in Kahuna’s range that does not have one.
AS 4989:2015 safety status
Kahuna publishes no safety standard for any trampoline they sell. We searched ten of their product pages, their homepage and five collection pages on 5 August 2026. There is no reference to AS 4989:2015 — and, unlike Jumpflex, Plum and Lifespan Kids, no reference to ASTM, CE or EN 71 either. This is the only brand we have checked directly that publishes nothing at all.
Our table reads "not verified by us" rather than something stronger, and the distinction is deliberate. Where a manufacturer publishes certifications and AS 4989 simply is not among them, we say so. Where a manufacturer publishes nothing, we cannot tell you whether the trampoline has been tested and the claim left off the website, or never tested. That is a genuine unknown and we are not going to convert it into an accusation. But it is an unknown you are entitled to weigh, and it takes one phone call to their Australian customer service line to resolve.
What we can tell you is observable rather than certified, and it is better than we expected. The entry is a zip-and-clip safety lock that closes completely — the entry point is the single most common place for an enclosure to leave a gap, and an overlapping flap is what we criticise the Lifespan for. The net is fine mesh, mounted so that jumpers cannot reach the frame or springs. Padding and netting are both UV-stabilised. And an anchor kit is in the box, which is not a certification but is the accessory most likely to prevent an actual incident in an Australian storm season.
The shape-specific point worth making: the standard governs structural strength, enclosure protection and entrapment gaps, but it does not tell you whether a given bounce profile suits a given child. A rectangle is not less compliant than a round — it is differently suited, and matching the shape to the age of the jumper is a judgement the standard leaves to you.
One number that puts the range in perspective, because it is the kind of thing a standard would not surface for you. Kahuna's ratings scale cleanly with size: 80kg at 8ft, 100kg at 10ft, 125kg at 12ft, 150kg at 14ft, and 150kg for this rectangular. Their 8ft is rated 80kg — the same as our A$2,086 top pick. Size, not price, is what drives that figure.
Verdict
If you want a rectangular trampoline in Australia and you want to buy it without a special order, this is still the pick, and the specification is stronger than we could show you before: 150kg, a zip-and-clip entry that closes properly, a net mounted inside the frame and springs, and an anchor kit in the box. A$875 with free delivery is a fair deal and the shape is genuinely better for older jumpers.
Go in knowing the two things Kahuna do not put in front of you. The frame is powder-coated where the rest of their range is galvanised — that is the one specification most likely to decide whether this trampoline is still sound in ten years, and it is the reason this sits fifth rather than higher. And they publish no safety standard at all, which on a page built around AS 4989:2015 is not something we can wave through.
If your children are under about eight, buy a round instead. The bounce that makes this trampoline good is the reason it is the wrong choice for them. And if a galvanised frame matters more to you than the rectangular shape, Kahuna's own 8ft x 14ft oval is galvanised, rated to the same 150kg, and was listing at A$892 on Amazon.
