Do You Need to Register an Inflatable Boat in Australia? The 2026 State-by-State Rules

Short answer: in every Australian state and territory, the moment you bolt a motor onto an inflatable boat — even a 2.5hp tiller outboard or a 30lb electric — it has to be registered. Yes, even a roll-up inflatable. Yes, even if you only use it once a year. No, the dealer is not legally required to tell you.

This is the single most-asked question we get in the showroom — usually from someone who bought a cheap inflatable online and only found out at a boat ramp when a Maritime officer pulled them over.

The rules are not complicated. They are just buried inside seven different state and territory websites that all use different wording, different fees and different definitions of "registrable vessel". Below is the plain-English version for 2026, state by state, with the actual links you'll need.

The one rule that applies everywhere

If your inflatable boat is fitted with a mechanical means of propulsion — petrol outboard, electric trolling motor, or any combustion or electric drive — it must be registered with your state's marine authority before you launch it on public waters.

The size of the boat doesn't matter. The horsepower doesn't matter (a 2hp counts the same as a 90hp in NSW, QLD, WA, TAS and NT). Whether it's a hard-sided tinny or a foldable inflatable doesn't matter.

A handful of states give you a horsepower-based exemption (SA and VIC both have one), but the safe assumption — and the one every Maritime officer in Australia works off — is motor = registration.

---

NSW — Transport for NSW (Maritime)

Rule: Any vessel fitted with a motor — petrol or electric, any horsepower — must be registered. Vessels under 5.5m without a motor (rowed, paddled, sailed under 3m sail) don't need rego.

What you'll need:

• Hull Identification Number (HIN) or Boat Code. Aerowave catamarans ship with the HIN moulded into the transom plate and printed on the CE compliance plate — bring photos of both.
• Proof of ownership (your tax invoice from Easy Inflatables works).
• A boat licence if the motor exceeds 4.5kW (about 6hp) and you're driving at more than 10 knots.
• Annual fee: roughly $80–$130 depending on length (2026 schedule).

Apply: Any Service NSW centre, or online at service.nsw.gov.au.

---

Victoria — Transport Safety Victoria

Rule: Every recreational vessel fitted with an engine — regardless of horsepower — must be registered. Vessels propelled only by oars, paddles or a sail under 3m² are exempt.

What you'll need:

• HIN.
• Proof of ownership.
• Marine Licence for any powered vessel over 5 knots.
• A "Vessel Operator Licence" is mandatory for the skipper, even on a tender.

Apply: transportsafety.vic.gov.au — VicRoads handles the actual registration.

---

Queensland — Maritime Safety Queensland

Rule: Any vessel powered by a motor of more than 3kW (about 4hp) must be registered. A small inflatable with a 2.5hp may legally escape rego — but anything bigger (and the moment you upgrade) needs to be on the books.

What you'll need:

• HIN and proof of ownership.
• Recreational Marine Driver Licence if the motor is over 4.5kW.
• Annual fee from approximately $35 (under 4.5m) up to several hundred for larger hulls.

Apply: tmr.qld.gov.au/Boating.

---

Western Australia — Department of Transport

Rule: Any powered recreational vessel — any horsepower — must be registered with DoT.

What you'll need:

• HIN.
• Proof of ownership.
• Recreational Skipper's Ticket (RST) for any motor over 4.5kW.
• Fees scale with hull length; expect $90–$160 a year for a typical inflatable catamaran.

Apply: transport.wa.gov.au/imarine.

---

South Australia — Department for Infrastructure & Transport

Rule: A powered vessel over 4kW (about 5.4hp) must be registered. Anything 4kW and under can be operated without rego — one of the most lenient regimes in the country.

This is where a lot of inflatable owners get caught out. A 5hp two-stroke and a 6hp four-stroke straddle the threshold; if you can't produce a manufacturer's plate showing kW, the SA inspector will treat it as registrable.

Apply: dit.sa.gov.au/boating.

---

Tasmania — Marine and Safety Tasmania (MAST)

Rule: Every motorised recreational vessel must be registered — no horsepower exemption.

What you'll need:

• HIN.
• Proof of ownership.
• Motor Boat Licence for the operator if the engine is over 4hp.
• Annual fee from around $69 (under 4m) up.

Apply: mast.tas.gov.au.

---

Northern Territory — NT WorkSafe (Marine Safety)

Rule: All motorised vessels must be registered with the NT Government.

What you'll need:

• HIN, proof of ownership, and the operator does not need a boat licence in NT (one of the few jurisdictions in Australia where recreational licensing is not yet mandatory).

Apply: nt.gov.au/marine.

---

ACT — Access Canberra

The ACT does not maintain its own marine register. If you live in Canberra and trailer your inflatable to Lake Burley Griffin or onto NSW waters, you register in NSW under your residential address.

---

What about an electric trolling motor?

Yes. Every state treats electric and petrol the same for registration. A 30lb-thrust Minn Kota on a 3.3m inflatable is a "mechanical means of propulsion" — NSW, VIC, QLD, WA, TAS and NT all require rego the moment it's bolted on. SA's 4kW exemption applies (most trolling motors are under 1kW), but even there you must still display a "registration not required" sticker on freshwater dams.

---

What about kayaks, paddle boards and rowed tenders?

Unpowered = no registration in every state. The instant you add even a small electric kicker, the rules above kick in.

Why every Aerowave is registration-ready out of the box

A lot of the cheap online inflatables sold in Australia don't carry a Hull Identification Number — which means they cannot legally be registered anywhere. You discover this after the sale, at the boat ramp.

Every Aerowave inflatable catamaran we sell is almost registration-ready out of the box — the only step left on you is the Boat Code "pink slip" inspection (covered below). Every Aerowave ships with:

1. A factory-stamped HIN moulded into the transom.
2. A CE compliance plate (ISO 6185-3, EU Directive 2013/53/EU) screwed to the hull.
3. A commercial-grade invoice from Easy Inflatables that satisfies every state's "proof of ownership" requirement.
4. A spec sheet listing hull length, beam and maximum power in kW — the three numbers every Maritime registration form asks for.
5. One last step that's on you: a Boat Code Certificate (the "pink slip" of the boating world). You arrange this yourself once the boat arrives — either drive it to a marine workshop or book a mobile Boat Code certifier to come to your driveway. Typical cost is $120–$180, takes about 20 minutes, and it's a one-time inspection at first registration — unlike a car pink slip, you do not repeat it every year.

With that certificate in hand plus the Aerowave bundle above, you walk into your Service NSW / DoT / MSQ office and walk out with rego on the same visit. No "we'll need to inspect the hull" delays.

The Boat Code Certificate — what it actually is

Think of it as the pink slip for your boat. In NSW (and most states that require it), every vessel needs a Boat Code inspection at first registration so Maritime can verify the HIN, the CE plate, the capacity rating and the basic safety gear match what's on the rego form.

Two ways to get one:

• Mobile Boat Code certifier — they come to your home or the boat ramp. Easiest option for an inflatable because you don't need to launch. Search "mobile boat code [your suburb]" — most metro areas have 3–5 operators.
• Marine workshop or chandlery — drop the boat off, they inspect it on the trailer, you collect the certificate the same day.

What the certifier checks on an Aerowave:

• HIN matches the paperwork (already moulded into the transom — pass).
• CE compliance plate is fitted and legible (already fitted at the factory — pass).
• Capacity plate / maximum power rating is visible (already on the CE plate — pass).
• Required safety gear is on board (lifejackets, bailer, paddles, anchor — your responsibility to pack).

Because Aerowave hulls already carry the HIN, CE plate and capacity data from the factory, the inspection is basically a tick-and-flick. Most no-name imports fail at this step because they have no HIN at all.

Do this once, at first rego, and you're done forever.

Boat Code Certificate checklist — who to call and what to bring

Use this checklist to book your inspection and walk in prepared.

Who can issue the certificate

Provider type	Best for	How to book
Mobile Boat Code certifier	Inflatable boats on a trailer at home; no ramp launch needed	Google "mobile boat code [your suburb]" — most metro areas have 3–5 operators. Call and book a 20-minute driveway visit.
Marine workshop / chandlery	Boats already on a service schedule or if you want a hull check at the same time	Phone your local boat mechanic, chandlery or dealership. Ask if they have an accredited Boat Code inspector on staff.

Documents to bring (or leave on the boat)

• Tax invoice / proof of ownership from Easy Inflatables
• Photo of the HIN moulded into the transom (already on the boat)
• Photo of the CE compliance plate screwed to the hull (already on the boat)
• Driver's licence (the certifier will record your details on the form)
• Safety gear on board — at least one lifejacket per person, bailer, paddle, anchor & rope (required for the inspector to tick off)

Tip for mobile certifiers

Because Aerowave hulls are lightweight and trailerable, a mobile certifier can usually inspect the boat while it's still deflated and bagged on the trailer. You only need to inflate it if the HIN or CE plate is hard to read through the bag. Most operators have seen inflatables before and know the drill.

The trap: buying a second-hand inflatable

If you're buying a used inflatable boat from Gumtree or Marketplace, the first thing to check — before anything else — is whether it carries a HIN. No HIN, no rego, no resale, no insurance. The boat is effectively a pool toy.

Aerowave hulls keep their HIN for the life of the boat (it's moulded into the transom), so a used Aerowave is always re-registrable. Many no-name brands aren't.

---

What it actually costs in 2026 (typical inflatable, 3.3m–4.0m)

• NSW: $99/year + $26 admin
• VIC: $135/year (includes Search & Rescue levy)
• QLD: $48/year for vessels under 4.5m
• WA: $103/year for under 4.5m
• SA: $0 (exempt under 4kW) or $96/year
• TAS: $69/year under 4m
• NT: $46/year

These figures move every July — always confirm on your state authority's site before paying.
