Boat registration numbers work only when the height matches the hull, the colour separates from the paint, and the position stays visible above the waterline. Get one of those details wrong and you will be working at the ramp instead of getting out on the water.<\/p>\n<p>This guide is general information, not legal advice. It walks through the boat rego numbers each state asks for, the height, colour and position rules that vary between jurisdictions, and how cut vinyl characters are applied to the hull. Confirm the current rules on your own registration certificate before you commit to a set.<\/p>\n<div class=\"cheat-sheet\" style=\"background:#f8f6f3;border-left:4px solid #c9a96e;padding:20px 24px;margin:28px 0;\">\n<p><strong>The short version<\/strong><\/p>\n<ul>\n<li>Both sides of the hull in almost every state, with a sailing boat transom or stern option where the rules allow.<\/li>\n<li>The common heights are 150mm for boats that plane, 100mm for PWC in most states and 75mm in some small-boat cases.<\/li>\n<li>The number must contrast with the hull. Western Australia requires black characters, with a 7mm white surround when the hull is not white.<\/li>\n<li>Registration labels are no longer required in New South Wales and Queensland, but Victoria and Western Australia still use them.<\/li>\n<li>We cut the numbers and boat names. The government registration label is not something we supply.<\/li>\n<li>Check your registration certificate and your state&#8217;s current rules before ordering.<\/li>\n<\/ul>\n<\/div>\n<h2>What every state needs on boat registration numbers<\/h2>\n<p>Every state rule returns to the same four checks. How tall are the characters? Do they contrast with the hull? Where do they sit? Are they plain, upright capitals? Registration numbers are set in upright plain block capitals, and script or italic styles are for boat names only.<\/p>\n<p>The number is not the registration label. The label requirement has been removed in New South Wales and Queensland, while it still applies in Victoria and in Western Australia. Queensland requires registration for a boat or PWC from the 3kW engine threshold upward. The details below come from each state&#8217;s official boating pages, read on 9 October 2026.<\/p>\n<p>When you are ready to have the numbers cut, the <a href=\"https:\/\/printshop.paperlust.co\/products\/boat-registration-numbers\">boat registration numbers<\/a> page lets you set your number into the state rego layout, choose the height and colour, and approve a proof before anything is produced.<\/p>\n<figure class=\"wp-block-image ps-blog-img\" style=\"margin:32px auto;text-align:center;\"><img decoding=\"async\" src=\"https:\/\/printshop.paperlust.co\/blog\/wp-content\/uploads\/2026\/10\/boat-blog-b1i1-r19-baa43b.jpg\" alt=\"Pale chart with one registration number at four character heights of 200mm, 150mm, 100mm and 75mm, labelled by boat type\" data-no-lazy=\"1\" style=\"max-width:100%;height:auto;display:inline-block;border-radius:4px;\" \/><figcaption class=\"wp-element-caption\" style=\"font-size:0.85em;line-height:1.45;color:#666;margin-top:8px;text-align:center;\">A scale chart shows one registration number at four character heights, each labelled for a boat type.<\/figcaption><\/figure>\n<h2>Boat registration number size by state<\/h2>\n<div class=\"ps-fmt-tw\">\n<table style=\"width:100%;border-collapse:collapse;margin:20px 0;\">\n<thead>\n<tr style=\"background:#1a1a1a;color:#fff;\">\n<th style=\"padding:11px 16px;text-align:left;\">State<\/th>\n<th style=\"padding:11px 16px;text-align:left;\">Boats<\/th>\n<th style=\"padding:11px 16px;text-align:left;\">Jet skis and PWC<\/th>\n<th style=\"padding:11px 16px;text-align:left;\">Where and how<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"background:#f9f9f9;\">\n<td style=\"padding:11px 16px;\">New South Wales<\/td>\n<td style=\"padding:11px 16px;\">Powerboats at least 150mm, sailing boats at least 100mm<\/td>\n<td style=\"padding:11px 16px;\">At least 100mm<\/td>\n<td style=\"padding:11px 16px;\">Both sides, or the transom of a sailing boat.

A boat that can plane needs 150mm characters, while a boat that cannot plane can use 75mm characters on each side or on the stern. Western Australia adds a minimum width: every number and letter must be at least 25mm. In South Australia the height depends on the vessel&#8217;s length, so confirm the current South Australian rules before ordering. The Northern Territory and the ACT have no rule stated here, so ask the local authority.<\/p>\n<p>A height of 150mm covers powerboats that plane across New South Wales, Victoria, Queensland, Western Australia and Tasmania. Our state rego layouts use 150mm or 200mm characters, and the PWC layout uses 100mm or 150mm.<\/p>\n<h2>Jet ski rego stickers: PWC sizes and placement<\/h2>\n<p>Jet ski rego stickers and other personal watercraft numbers follow a smaller size set in most states. The 100mm minimum applies across New South Wales, Queensland and Victoria, as well as in Western Australia. Tasmania allows 75mm. South Australia ties the required height to the boat&#8217;s length. Check the current South Australian rules before ordering.<\/p>\n<p>Western Australia adds one placement rule. On a PWC the characters go on both sides of the hull or at midship, and must not sit beneath the bow flare. Choose the Jet ski and PWC rego layout at 100mm or 150mm when you order.<\/p>\n<figure class=\"wp-block-image ps-blog-img\" style=\"margin:32px auto;text-align:center;\"><img decoding=\"async\" src=\"https:\/\/printshop.paperlust.co\/blog\/wp-content\/uploads\/2026\/10\/boat-blog-b1i2t-57499f.jpg\" alt=\"A dark red half cabin boat on a trailer at a boat ramp under a grey sky, water and wooded hills behind.

A dark number reads on a white or light hull, while a lighter colour reads on dark gelcoat. Queensland frames it as a distance test. The number must be readable from 30m away, which is harder to do with navy characters on a black hull than with white or yellow characters.<\/p>\n<p>Some owners search for boat registration stickers. What we cut are vinyl characters with no background, so the hull colour shows between and inside each letter. Western Australia is the strictest on colour. It requires black characters in a plain block font, upright and not slanting. If the hull is not white, each character needs a white surround of at least 7mm. Our Western Australia layout uses Black characters and is for white hulls. We do not make the white surround option.<\/p>\n<p>The letters are cut from Avery 500 series 70 micron gloss calendered vinyl with a permanent adhesive. Ten standard gloss colours are available: Black, White, Dark Grey, Red, Orange, Yellow, Kelly Green, Light Blue, Reflex Blue and Magenta. Standard colours last up to 3 years outdoors, while black and white last up to 5 years. The metal-effect gold, rose gold and silver films are not offered on this page because they suit indoor and sheltered outdoor use.<\/p>\n<h2>Boat rego stickers: placement and application<\/h2>\n<p>Place the number on each side of the hull in almost every state. New South Wales allows a sailing boat to use the transom instead. Victoria wants the identification mark forward of midships. New South Wales also says the number must sit well above the normal waterline. Apply the letters above the waterline on a clean, dry, smooth painted or gelcoat hull panel.<\/p>\n<p>A 150mm number of up to six characters fits one piece per side, with the largest single piece at 600 x 260mm. 200mm numbers and longer boat names come as two pieces per side, and you line them up on the hull. Every letter is at least 20mm tall and every stroke at least 5mm thick at its thinnest point. Once a letter touches the surface it cannot be repositioned, and the letters are single-use. If a piece is damaged while you are putting it on, order that piece on its own as a single piece. A step-by-step guide on <a href=\"https:\/\/printshop.paperlust.co\/blog\/how-to-apply-vinyl-lettering-australia\">how to apply vinyl lettering<\/a> covers cleaning, positioning and the transfer-tape pull.<\/p>\n<figure class=\"wp-block-image ps-blog-img\" style=\"margin:32px auto;text-align:center;\"><img decoding=\"async\" src=\"https:\/\/printshop.paperlust.co\/blog\/wp-content\/uploads\/2026\/10\/boat-blog-b1i3-r19-fb67c1.jpg\" alt=\"Two strips of black cut vinyl registration characters at 150mm under clear transfer tape on cream backing paper\" data-no-lazy=\"1\" style=\"max-width:100%;height:auto;display:inline-block;border-radius:4px;\" \/><figcaption class=\"wp-element-caption\" style=\"font-size:0.85em;line-height:1.45;color:#666;margin-top:8px;text-align:center;\">Black cut vinyl registration characters at 150mm sit under clear transfer tape on cream backing paper.<\/figcaption><\/figure>\n<h2>Order boat rego numbers in the right height and colour<\/h2>\n<p>Ordering boat rego numbers starts with your state layout. Choose New South Wales, Victoria, Queensland, South Australia, Tasmania or Western Australia, then pick a character height, a Pair or Single piece, and a colour. The product page shows the price as you choose the layout, height, pair or single piece and colour.<\/p>\n<p>Type the registration number exactly as it appears on the registration certificate. If it is a New South Wales personalised number, it can be any combination of up to six letters and numbers and always ends in the letter N. Pair is one set for each side of the hull. Single piece is for a transom or stern, or for replacing one side.<\/p>\n<p>The team sets your number into the layout and emails a PDF proof. Nothing is cut until you approve that proof. If you have a cut-ready vector file in PDF, SVG or AI format, use the Upload my own artwork option. Custom design, where a designer creates the lettering from your brief, includes two design options on the first proof and three rounds of revisions for a one-off design fee.<\/p>\n<p>Production takes 3 to 5 working days after the proof is approved. That is production time, not delivery time. Delivery is charged once per order at checkout, or you can pick up from the Oakleigh South studio at no charge. If you need the order by a date, write it in the Special Request box at checkout and the team replies whether it can be met. The <a href=\"https:\/\/printshop.paperlust.co\/production-and-delivery\">production and delivery<\/a> page explains timing, checkout options and peak periods in more detail.<\/p>\n<h2>Frequently asked questions<\/h2>\n<h3>What height does New South Wales require for boat numbers?<\/h3>\n<p>New South Wales requires powerboats to use numbers at least 150mm high. Sailing boats and PWC need at least 100mm. The characters go on each side of the vessel, or on the transom of a sailing boat, and must sit well above the normal waterline so they can be seen at all times. Use solid, clear text in a colour that contrasts with the hull. Registration labels no longer have to be displayed there.<\/p>\n<h3>What does Queensland require for boat registration numbers?<\/h3>\n<p>Queensland requires registration for boats and PWC with an engine of 3kW or more. The number must be readable from 30m away and contrast with the hull. Boats that can plane need characters at least 150mm high on each side. Boats that cannot plane need at least 75mm high on either side or on the stern. PWC need at least 100mm high on both sides. Queensland no longer issues a registration label.<\/p>\n<h3>What size numbers does a jet ski need?<\/h3>\n<p>Jet ski and PWC numbers must be at least 100mm high in New South Wales, Queensland and Victoria, as well as in Western Australia. Tasmania allows 75mm as the minimum. South Australia sets the height by vessel length, so confirm current rules before you order. Western Australia also requires PWC characters to be at least 25mm wide and placed not beneath the bow flare.<\/p>\n<h3>What makes Western Australia different for boat registration numbers?<\/h3>\n<p>Western Australia requires black characters in a plain block font, upright and not slanting. Every number and letter on a motor boat must be at least 150mm tall and 25mm wide. If the hull is not white, each character needs a white surround of at least 7mm. PWC characters are at least 100mm tall and 25mm wide and must not sit beneath the bow flare. The registration sticker is fixed to the port side, next to the number.<\/p>\n<h3>Do I still need a registration label, and do you supply it?<\/h3>\n<p>New South Wales and Queensland no longer require a registration label to be displayed. Victoria still issues one, as does Western Australia. We cut vinyl registration numbers and boat names. The official government registration label or sticker is not supplied by us, so you will need to follow your state&#8217;s process for that label if one is still required.<\/p>\n<h3>How long do boat registration numbers last on a boat?<\/h3>\n<p>Our numbers are cut from Avery 500 series 70 micron gloss calendered vinyl. Standard colours last up to 3 years outdoors, while black and white last up to 5 years. The letters have no background, so the hull colour shows between and inside each character. Vinyl is single-use and cannot be repositioned after it touches the surface. If a piece is damaged during application, you can reorder that single piece on its own.<\/p>\n<p><script type=\"application\/ld+json\">\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"FAQPage\",\n  \"mainEntity\": [\n    {\"@type\": \"Question\", \"name\": \"What height does New South Wales require for boat numbers?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"New South Wales requires powerboats to use numbers at least 150mm high.
