Website accessibility means building your site so everyone can use it — including people with vision, hearing, motor or cognitive impairments. It's often treated as a technical afterthought, but it's three things at once: the right thing to do, a legal obligation in Australia, and a genuine business advantage. Around one in five Australians lives with disability, so an inaccessible site is turning away a sizeable chunk of your potential customers. This guide explains what accessibility involves and where to start.
Why accessibility matters
There are three reasons to take it seriously, and they reinforce each other.
It's a large audience. Roughly 4.4 million Australians have some form of disability, plus an ageing population that benefits from clearer, easier-to-use sites. Locking them out is lost business.
It's the law. Under the Disability Discrimination Act 1992 (DDA), goods and services — including websites — must not discriminate against people with disability. There's established Australian precedent that inaccessible websites can breach the DDA. Government sites are held to formal standards, and private businesses are expected to make reasonable adjustments.
It helps everyone, including Google. Many accessibility practices — clear structure, descriptive text, captions, good contrast — also improve usability for all visitors and feed directly into SEO. An accessible site is usually a better, more findable site.
The standard to aim for: WCAG
The internationally recognised benchmark is the Web Content Accessibility Guidelines (WCAG). Australian government policy and most legal guidance point to WCAG 2.1 (or later) at Level AA as the practical target. You don't need to memorise the full standard, but it's built on four principles worth knowing — content should be Perceivable, Operable, Understandable and Robust (POUR).
In plain terms: people must be able to perceive your content (e.g. with a screen reader), operate your site (e.g. with a keyboard), understand it, and have it work reliably across browsers and assistive technologies.
The fixes that matter most
You don't have to do everything at once. These high-impact basics cover the majority of real-world accessibility problems.
Colour contrast
Text needs enough contrast against its background to be readable, including for people with low vision or colour blindness. Pale grey text on white is a common culprit. WCAG sets specific contrast ratios; free checkers will tell you if you pass.
Alt text for images
Every meaningful image needs descriptive alternative text so screen readers can convey it. Decorative images can be marked to be skipped. As a bonus, good alt text also helps search engines understand your images.
Keyboard navigation
Many people can't use a mouse and navigate entirely by keyboard. Every link, button and form field must be reachable and usable with the Tab and Enter keys, with a visible focus indicator showing where they are.
Clear structure and headings
Use proper heading levels (H1, H2, H3) in order, not just for visual size. Screen readers use them to navigate, and they make pages easier for everyone to scan — the same skim-friendly structure good website copywriting relies on.
Descriptive links and labels
"Click here" tells a screen-reader user nothing out of context. Write links that describe their destination ("read our pricing guide"). Label every form field clearly so it's obvious what's required.
Captions and transcripts
Video needs captions and, ideally, transcripts so people who are deaf or hard of hearing — and anyone watching with the sound off — can follow along.
Forms that explain themselves
Forms should have clear labels, helpful instructions, and error messages that say what went wrong and how to fix it, not just turn a field red.
How to check your site
Start with a quick self-audit. Try using your own site with only the keyboard — no mouse — and see if you can complete the key tasks. Run a free automated checker (such as WAVE or Google Lighthouse, which includes an accessibility audit) to catch common issues. Test your colour contrast with an online tool.
Automated tools catch maybe half of all issues, so for anything customer-critical, manual testing — ideally with real assistive-technology users — fills the gap. A site overhaul is also a natural moment to bake accessibility in from the start rather than retrofit it; our website redesign checklist is a good companion.
Build it in, don't bolt it on
Accessibility is far cheaper and better when it's part of how a site is designed and built, rather than patched on at the end. The good news is that an accessible site overlaps heavily with a fast, well-structured, mobile-friendly one — so the work pays off across SEO, usability and reach at the same time. It's a core part of what a quality small business website checklist should include.
Frequently Asked Questions
Is website accessibility a legal requirement in Australia?
Yes. The Disability Discrimination Act 1992 makes it unlawful to discriminate against people with disability in providing goods and services, and this has been applied to websites. Government sites must meet formal WCAG standards, and private businesses are expected to make reasonable adjustments so their sites are accessible. Beyond the law, it's simply good practice.
What is WCAG?
WCAG stands for the Web Content Accessibility Guidelines, the international standard for making web content accessible. It's organised around four principles — content should be perceivable, operable, understandable and robust. In Australia, the practical target for most organisations is WCAG 2.1 Level AA, which covers the issues that affect the most users.
Does accessibility help SEO?
Yes, considerably. Many accessibility practices — descriptive alt text, proper heading structure, clear link text, captions, fast and mobile-friendly pages — are also things search engines reward. Building an accessible site tends to produce a cleaner, better-structured site that ranks well, so the two goals reinforce each other.
How do I check if my website is accessible?
Start by navigating your site using only a keyboard and running a free automated tool like WAVE or Google Lighthouse, plus a colour-contrast checker. These catch common problems quickly. Automated tools miss around half of all issues, though, so manual testing — ideally involving people who use assistive technology — is important for anything critical.
