Australian Web Accessibility Standards- What You Need to Know (and Do)

What is Web Accessibility?

Web accessibility means designing and developing websites so that users with disabilities can use them effectively. Disabilities may include visual, auditory, cognitive, or physical impairments. Visual disabilities can be blindness, low vision, or colour blindness. Auditory disabilities include deafness or hearing loss. Cognitive disabilities cover conditions like dyslexia, ADHD, or autism. Physical disabilities refer to limited or no motor control.

A WCAG-compliant website is achieved when designers and developers employ design principles, coding techniques, and content strategies that facilitate easy access for users with disabilities.

Understanding Australia’s Accessibility Standards and Legal Frameworks

DDA and Why It Matters

The Disability Discrimination Act 1992 (DDA) is the cornerstone of digital accessibility legislation in Australia. It prohibits discrimination against individuals with disabilities in all areas of public life, including access to digital platforms such as websites, mobile apps, and online services. If your website is not accessible, your organisation could be seen as limiting equal access to information and services.

Several high-profile cases demonstrate how this plays out in practice. In 2014, Coles Group faced legal action due to the inaccessibility of its online shopping platform. Similarly, RailCorp was challenged in 2011 for its inaccessible website and ticketing system. These cases highlight the reputational and financial risks organisations face when accessibility is not prioritised.

Complying with the DDA is more than legal protection. It signals inclusion and social responsibility, particularly for sectors that serve vulnerable or marginalised communities.

WCAG 2.1, 2.2 and AS EN 301 549

Australia follows the Web Content Accessibility Guidelines (WCAG) as the technical standard for digital accessibility. The current expectation for public-facing websites is to meet WCAG 2.1 Level AA. This version builds on WCAG 2.0 by addressing additional user needs, particularly mobile usability, low vision, and cognitive limitations. WCAG 2.2, while newer, is not yet mandatory but is increasingly referenced in planning forward-looking digital experiences.

Another necessary standard is AS EN 301 549:2020. This guideline applies to information and communication technology (ICT) procured by the Australian Government. It sets out detailed accessibility requirements for everything from websites and apps to software and support systems. This standard influences tender eligibility and compliance obligations for organisations with or within government.

Understanding how WCAG and AS EN 301 549 relate helps teams consistently apply accessibility principles across projects, platforms, and procurement processes.

Review your website for accessibility compliance

Why not have Butterfly review your current website? Our team will provide you with a bundled assessment, including a WCAG 2.1 (Level AA) report, heuristic (usability) analysis, and performance report. We quickly provide a holistic review of your website to help you on your way towards peace of mind.

Practical Steps to Achieve Accessibility Compliance

1. Start With an Accessibility Audit

The best place to begin is with an audit. It reveals where your website stands and what barriers exist for users with disabilities. In Australia, the benchmark for accessibility is WCAG 2.1 Level AA. Still, auditing also needs to consider how your organisation fits within broader frameworks like the DDA and, if applicable, AS EN 301 549.

Accessibility audits should use a combination of automated tools and manual user testing. Tools like WAVE, Lighthouse, and Accessibility Insights help catch issues at scale, but they can’t interpret intent, usability or real-world barriers. Manual audits—particularly using screen readers, keyboard navigation, and mobile devices—bring a human layer of insight that tools can’t replicate.

Common issues flagged in Australian audits include:

Missing or vague alt text for images

Low colour contrast between text and backgrounds

Non-keyboard accessible menus or forms

Videos without captions or transcripts

Complex or inconsistent navigation structures

Forms that don’t offer clear error messaging or input guidance

PDFs that are not readable by screen readers

2. Fix What Matters Most First

An audit will likely uncover dozens of issues, but not all carry the same weight. Knowing what matters most for compliance, risk, and user experience is key. In the Australian context, issues that breach WCAG 2.1 Level A or AA should be prioritised, as this is the government-backed standard most likely to be used in legal assessments under the DDA.

If your organisation is part of the public sector or works with the government, refer to AS EN 301 549. Failing to meet these standards can impact not only your users but also your eligibility for tenders and funding.

Butterfly’s approach is to triage issues by severity, legal risk, and user impact:

Level A violations (e.g. missing alt text, inaccessible forms) are non-negotiable and must be fixed first.

Level AA items (e.g. colour contrast, consistent navigation) come next.

Design or structural changes that improve experience but don’t affect legal compliance can be scheduled for later improvement phases.

This phased, risk-based roadmap helps teams move forward with clarity and confidence, rather than being overwhelmed by a laundry list of tasks.

3. Train Your Team

One of the most overlooked steps in achieving accessibility is team capability. Fixing issues once is not enough. Sustainable accessibility comes from building internal understanding across content, design, and development teams.

This often requires cross-functional collaboration in Australian organisations, particularly in education, healthcare, or government. For example, your marketing team may manage content updates, while IT handles platform upgrades. Without a shared understanding of WCAG principles, accessibility decisions can easily fall through the cracks.

Training your team helps prevent regressions, shortens project cycles, and improves accountability. It also demonstrates to regulators and stakeholders that your organisation is actively maintaining compliance, not just reacting to it. Building knowledge is a strategic investment, whether it’s formal workshops, internal documentation, or working with a partner like Butterfly.

4. Keep Improving

Compliance is not a one-time event. As content changes, platforms evolve, and standards update (like the transition from WCAG 2.1 to 2.2), accessibility must be reviewed and refined continuously.

This is especially important for Australian organisations subject to public scrutiny or funding audits. Maintaining digital integrity involves conducting scheduled accessibility reviews, inviting user feedback, and staying updated on changes from the Digital Transformation Agency (DTA).

Ongoing improvement also creates operational efficiency. Fixes are smaller, less costly, and more integrated when accessibility is part of your regular delivery rhythm, not something retrofitted at the end.

Butterfly supports many of its long-term clients through structured maintenance cycles and regular audits. This ensures accessibility isn’t a separate burden, but part of how your organisation builds trust, serves its audience, and stays ahead.

Common Web Accessibility Challenges (and How to Solve Them)

Even with the right tools and intentions, many organisations hit barriers when working towards accessibility compliance. These challenges are common across sectors but are also solvable with the right mindset and support.

Accessibility vs Design Aesthetics

One of the most persistent myths is that accessibility leads to unattractive, restrictive design. This tension often arises when design teams worry about compromising visual identity to meet WCAG guidelines.

Accessible design and beautiful design are not mutually exclusive. In fact, accessibility often improves clarity, readability, and engagement across all user groups. Colour contrast, logical hierarchy, and consistent interaction patterns are good design principles regardless of ability.

Butterfly’s experience in sectors like health and education shows that accessibility can be fully integrated into a creative brief, without sacrificing brand quality or innovation.

Unclear Ownership and Responsibility

Another challenge is knowing who within the organisation is responsible for accessibility. It’s rarely just one person’s job. In many mid-sized teams, the responsibility is shared across marketing, IT, content authors, and procurement.

The risk here is diffusion when everyone assumes someone else is handling it. This is especially problematic in regulated or government-funded spaces, where compliance is expected but not always assigned.

The most effective solution is to embed accessibility into governance. This includes internal checklists, documented responsibilities, and a delivery process where accessibility is a defined stage, not an afterthought.

Navigating Procurement and Compliance Standards

Procurement adds another layer of complexity for organisations that work with or are funded by the government. Accessibility is no longer a preference—it’s a requirement in vendor selection. Standards like AS EN 301 549 are often listed in tenders, and failing to meet them can disqualify your organisation or create friction in compliance audits.

This is where partnering with a team that understands these expectations, like Butterfly, can be critical. We don’t just deliver compliant assets. We provide documentation, audit trails, and technical responses that help our clients navigate procurement confidently.

Why Investing in Accessibility Pays Off

Web accessibility is often seen as a compliance exercise, but the benefits go far beyond avoiding risk. For many Australian organisations, investing in accessible digital platforms improves performance across marketing, operations, customer experience, and brand reputation.

Inclusion That Reflects Your Values

Australia is home to over 4.4 million people living with a disability—that’s nearly one in five Australians. Making your website accessible is a tangible way to serve this audience and signals that your organisation is inclusive, thoughtful, and future-ready. This alignment with values is especially important for organisations in health, education, or government.

Access to a Larger Market

Globally, people with disabilities represent a market of more than 1 billion individuals, with a combined purchasing power exceeding $13 trillion. Excluding this audience doesn’t just limit your impact—it shrinks your potential reach. Accessibility opens your services and communications to a much broader and often underserved group.

Better Experience for All Users

Accessible websites are faster, easier to navigate, and better structured. These qualities benefit every user, not just those with impairments. Features like clear headings, keyboard navigation, and responsive layouts improve engagement across devices and demographics.

SEO and Discoverability Gains

Search engines reward websites that are semantically structured and easy to navigate. Many accessibility best practices—like using descriptive headings, alt text, and clean HTML—overlap with technical SEO guidelines. The result is better visibility and higher-quality traffic.

Reduced Risk and Cost of Remediation

When accessibility is built in from the start, it reduces the risk of complaints, legal claims, and later costly redevelopment. For public-facing Australian organisations, this isn’t just smart, it’s increasingly expected.

Butterfly’s Approach to Accessibility- Strategic, Practical, Ongoing

For Australian organisations, digital accessibility is a legal and ethical imperative. It is governed by the Disability Discrimination Act (DDA) and guided by WCAG 2.1 Level AA and AS EN 301 549:2020. Accessibility compliance ensures equal access for all users and safeguards your organisation against reputational and legal risk.

But navigating these standards isn’t always straightforward. With evolving requirements, rising expectations from funding bodies, and real-world legal cases (like Coles and RailCorp discussed above), it’s clear that a checklist approach isn’t enough. What’s needed is a strategic, ongoing commitment.

That’s where Butterfly comes in. As the leading web development agency in Melbourne, with deep experience in government websites, healthcare, and for-purpose sectors, we help teams go beyond compliance. Our accessibility audits, design-led remediation, and long-term support ensure your website is not only compliant but also built to perform, include, and endure.

Our process starts with a tailored accessibility audit using automated and manual testing to identify compliance gaps and usability issues.
