Quick answer: Yes, custom-fit boot liners exist for the BYD Sealion 7 (2025 onwards) in Australia, priced roughly $99.95–$129.00 AUD. Choose TPE for year-round flexibility or rubber for heavy-duty use. Confirm your build year and check for optional boot-mounted subwoofers before ordering.
Does a boot liner fit?
A custom-fit BYD Sealion 7 boot liner is available for Australian-delivered vehicles from the 2025 model year onwards. Early buyers found out the hard way: owners report that high demand wiped out initial stock within weeks of the Sealion 7's Australian launch, leaving some without protection for a month or more.
Custom-fit liners are moulded to the Sealion 7's exact cargo floor profile, including the raised lip at the tailgate sill. A universal mat will not replicate that fit — it shifts under load and leaves the corners of the boot floor exposed.
For Sealion 6 owners, custom-fit liners covering the 2024 model year onwards are separately available in Australia, with pricing in the same $99.95–$129.00 AUD range. Both vehicles have their own distinct mould; stocking up before a road trip is worth doing early given how fast these sell.
We cross-check listings against factory floor dimensions before recommending any liner on this platform, so the vehicles confirmed below reflect real fitment data, not marketing copy.
Which material suits Australia?
Picture loading sandy surfboards into your Sealion 7 after a summer session, or pulling up a red-dirt track after a weekend camp. The material your boot liner is made from determines how it holds up to that kind of use over multiple Australian summers.
XPE (cross-linked polyethylene foam) is lightweight and has a closed-cell structure that resists moisture. The trade-off is that XPE can lose some rigidity in sustained extreme heat — boot space in a dark-coloured SUV parked in direct sun can exceed 40°C, which is worth factoring in if you park outdoors all day.
TPE (thermoplastic elastomer) stays flexible across a wider temperature range, produces no noticeable chemical odour, and is fully recyclable. It tends to be the material of choice for families doing school runs, beach trips, and general all-weather use across most Australian climates.
Rubber liners are the heaviest option and the most rigid at room temperature. They provide maximum grip and resist tearing under sharp loads — the right call for tradesperson use or genuinely loaded off-road touring. Rubber is what Rubbertree Australia stocks for the Sealion 7 at $129.00 AUD.
For an all-weather XPE set that covers both floor and boot in one order, the Tailor-made XPE Car Floor & Trunk Mats at $280.00 is a bundled option we stock. It is a full interior kit moulded for waterproofing and anti-slip performance, and the closed-cell XPE construction means liquids cannot soak through to the carpet below.
| Material | Heat tolerance | Weight | Best use |
|---|---|---|---|
| XPE | Moderate — can soften above 40°C | Light | Daily, beach, school run |
| TPE | Good across full range | Medium | All-weather, families |
| Rubber | Excellent rigidity | Heavy | Off-road, trades |
What about the under-boot area?
The Sealion 7 has a storage well beneath the main cargo floor. Owners report the under-boot space is notably tight — a full-size spare tyre barely fits — so anything that reduces access or effective depth is a real concern.
Most custom-fit boot liners on the Australian market cover the main cargo floor only. The under-boot well and its access panel are typically left uncovered, which is not a flaw — it is by design so you can still lift the panel to reach the well beneath without cutting or removing the liner.
Where it matters: confirm before purchase whether the liner you are ordering is main-floor-only or includes a secondary tray for the subfloor area. We have not found a current Australian listing that includes a moulded sub-floor insert for the Sealion 7 as a standard bundle; a separate rubber tray cut to well dimensions is the practical workaround some owners use.
The access panel itself must remain unobstructed. A correctly fitted liner sits within the cargo floor recess and does not overlap the panel edge. If a liner is sitting proud of the floor edges, that is a fitment signal to re-check the SKU against your build year.
Under-boot panel access: Do not tuck the boot liner under the under-boot access panel edge. The panel must lift freely for tyre and storage access. If your liner overlaps the panel hinge line, the SKU may be incorrect for your variant — contact the retailer before cutting or forcing the material.
Sealion 6 vs Sealion 7 liner: same?
No. The BYD Sealion 6 boot liner and the Sealion 7 liner are separate products with separate SKUs. Buying one in a hurry — second-hand or from a listing that does not clearly state the model — and fitting it to the other vehicle will result in a liner that does not sit flush, leaves gaps, or cannot accommodate the tailgate sill correctly.
The Sealion 6 and Sealion 7 share a platform architecture but have different body profiles and cargo compartment dimensions. BYD does not publish a direct boot volume comparison between the two on the Australian site, so we will not invent a number — check your handbook or the BYD Australia configurator for the figure relevant to your model.
Both liner variants are confirmed available in the Australian market: the Sealion 6 from 2024 onwards, the Sealion 7 from 2025 onwards. Multiple Australian retailers list them as distinct products at comparable price points. If you are buying a liner second-hand, verify the exact model label on the packaging before accepting the item.

Must-have accessories to bundle?
Owners consistently report that a boot liner and floor mats are the first two accessories purchased after taking delivery of a Sealion 7. The logic is straightforward: muddy boots at the door, groceries spilling on the way home, wet gear from the coast — neither the carpet nor the floor mats that came with the vehicle are built to absorb that daily load without staining.
The Tailor-made XPE Car Floor & Trunk Mats at $280.00 covers both the floor and boot in a single purchase. That bundle removes the risk of ordering mismatched products from separate suppliers and arriving with coverage gaps between the front footwells and the cargo area.
For families and pet owners, a back seat protector is the third item that comes up repeatedly in owner discussions. It handles the scenario the boot liner cannot: a dog shaking off creek water on the rear bench, or kids climbing in with sandy feet.
The 2018-2026 BYD Tang 5D Full-Coverage Pet Car Seat Cover at $91.00 is available in our range and provides full bench coverage including the seat back, which is where pet claw damage accumulates fastest.
Bundling liner, floor mats, and a seat protector at the point of vehicle delivery keeps the interior in resalable condition from day one, which is a practical consideration for a vehicle at the Sealion 7's price point.
How to check fit before buying?
Before placing an order, confirm your exact build year. The Sealion 7 launched in Australia in 2025; if you are reading this in 2026, verify whether your vehicle is a 2025 or 2026 build on the compliance plate inside the driver's door jamb. Liner moulds can be updated between production runs.
Check whether your vehicle has an optional subwoofer mounted in the boot area. Some Sealion 7 configurations include a speaker unit positioned against the boot wall or floor, and this changes the usable cargo floor shape — a liner moulded without that protrusion in mind will not sit flat.
If you are unsure, measure the boot floor length, width, and tailgate lip height before ordering and compare against the retailer's listed dimensions.
Under Australian Consumer Law, custom-fit products occupy a specific category: if a product is made to your specification or clearly described as custom-fit for a nominated vehicle, standard change-of-mind return rights may not apply. Confirm the retailer's exchange policy in writing before purchase, particularly if your vehicle has a non-standard boot configuration.
Cross-reference the product SKU against your model on the BYD Sealion 7 accessories listings to verify the exact applicability note. If the listing reads '2025 onwards' and your vehicle is a 2025 build, that is a match — but flag any optional accessories to the retailer before confirming the order.

FAQ
Will a BYD Sealion 6 boot liner fit the Sealion 7?
No. Despite sharing a platform, the Sealion 6 and Sealion 7 have different boot dimensions and require separate liner moulds. Multiple Australian retailers list them as distinct SKUs, and cross-fitting will result in poor coverage and gaps at the sill.
What does a BYD Sealion 7 boot liner cost in Australia?
Custom-fit liners range from approximately $99.95 to $129.00 AUD depending on material and supplier. TPE options sit toward the lower end; rubber liners from specialist retailers tend to reach the higher price point.
Does the boot liner cover the under-boot storage well?
Most Australian-market liners cover the main cargo floor only. The under-boot well and access panel are typically left uncovered so you can lift the panel freely. Confirm with the retailer before purchase if sub-floor coverage is a priority for you.
Does an optional subwoofer affect boot liner fitment?
Yes. Some Sealion 7 configurations include a boot-mounted speaker that alters the usable floor profile. Notify the retailer of any optional boot-area accessories before ordering to confirm the liner mould will sit flat in your specific vehicle.
What material is best for Australian conditions?
TPE is the most versatile choice for Australian all-weather use, staying flexible across temperature extremes without noticeable odour. Rubber suits heavy-duty or off-road use; XPE is a lightweight option but can soften slightly in boot spaces exceeding 40°C.
