How much does a custom website cost in Australia in 2026?

A custom website in Australia costs between $4,500 and $80,000 AUD ex-GST in 2026. The range is wide because 'custom website' covers everything from a five-page marketing site for a local trade business through to a headless Shopify Hydrogen build for an eight-figure DTC brand. According to the Australian Bureau of Statistics' Counts of Australian Businesses, there were approximately 2.66 million actively trading businesses in Australia as of June 2024; the agency market that serves them is highly fragmented, with prices for the same scope often varying by 2–3x between studios. This guide breaks the market into four honest price bands, explains what drives the cost in each, shows where the value actually sits, and lists the hidden costs that often turn a $15,000 quote into a $22,000 invoice. Every figure is quoted in AUD ex-GST unless otherwise stated.

What are the four price bands for custom websites in Australia in 2026?

The Australian custom-web market splits into four price bands in 2026: local-trade sites at $4,500–$8,000, premium marketing sites at $10,000–$25,000, custom Shopify storefronts at $12,000–$40,000, and headless or enterprise builds from $40,000 to $80,000+. Local-trade sites cover plumbers, electricians, single-location clinics, and small service businesses, and are the largest band by volume — the ABS counts roughly 800,000 sole-trader businesses across the country. Premium marketing sites cover service businesses, SaaS startups, design studios and agencies — anywhere brand and conversion compound. Custom Shopify sits in band three because the platform's complexity (theme architecture, Liquid templating, checkout limitations on the standard tier) requires more specialist time than a marketing site of equivalent visual scope. Headless or enterprise builds cover multi-region commerce, ERP-integrated catalogues, and bespoke checkout flows where Shopify standard cannot meet the requirement.

Why does a marketing site cost $10,000 when a Wix template is $30 a month?

A Wix or Squarespace template costs $30 per month because it is a known-good design applied to your brand by you. A custom site at $10,000 pays for design and engineering judgement applied to your specific brand, audience and conversion goal — work the template cannot do because it does not know your audience exists. The work that drives the cost in band two is design direction (3–6 weeks of senior designer time), copy collaboration with the founder, performance budgeting against Google's Core Web Vitals thresholds (Largest Contentful Paint under 2.5 seconds, Interaction-to-Next-Paint under 200ms, Cumulative Layout Shift under 0.1), motion craft, schema markup, and WCAG 2.2 AA accessibility compliance. Templates ship none of these as standard. The day a templated site stops converting is the day you discover you cannot meaningfully fix it without rebuilding off the platform — which is when buyers in the $10,000 band end up in the $20,000 band twelve months later.

What drives a custom Shopify build over $20,000?

Three things drive Shopify cost above the $20,000 mark. First, custom theme development on Shopify 2.0 with section-based merchandising — not a fork of the free Dawn theme — typically adds $8,000–$15,000 in design and Liquid templating time. Second, product detail page (PDP) conversion-rate work: social proof, Australian shipping clarity, BNPL placement (Afterpay, Zip, Klarna), and variant logic typically add $5,000–$10,000 and is the highest-ROI line item in the build. Australia has one of the highest BNPL adoption rates globally — the Reserve Bank of Australia has reported BNPL transactions accounting for approximately 2% of all card-and-BNPL spending, and the share continues to grow among 18–34 year olds. Third, migration mapping if you are moving from WooCommerce, Magento or a legacy platform — preserving SEO equity through redirect mapping, schema continuity and URL pattern preservation is engineering work, not a button you press, and typically adds $3,000–$8,000.

• Custom Shopify 2.0 theme (vs. paid template): +$8,000–$15,000
• PDP-up CRO work with behavioural testing: +$5,000–$10,000
• Migration from WooCommerce or Magento with redirect mapping: +$3,000–$8,000
• Headless Hydrogen build: +$15,000–$40,000
• Custom checkout / Shopify Plus scripts: +$5,000–$15,000

How much does ongoing maintenance cost?

Maintenance on a custom Australian website typically runs $300 to $2,500 per month depending on build complexity and how much ongoing CRO or content work is bundled in. A purely technical 'keep the lights on' retainer — hosting, uptime monitoring, minor bug fixes, security and dependency updates — runs $300–$800 per month for a marketing site, or $600–$1,500 for a custom Shopify storefront. Add design and CRO iteration (monthly A/B tests, copy experiments, schema updates, performance monitoring) and the number lands between $1,500 and $2,500. Small businesses that invest in monthly site iteration typically grow conversion rates several times faster than those that treat launch as 'done', which is why most agencies including ours bundle maintenance with light CRO rather than offering pure technical retainers below $500 per month. Hosting itself is rarely the dominant cost — Vercel or Cloudflare hosting for a typical marketing site runs $0–$200 per month at SMB traffic levels.

Is GST included in the prices in this article?

No — every figure in this guide is quoted ex-GST, as is standard practice across the Australian agency market. The Australian Taxation Office requires registered businesses earning $75,000 or more per year to add 10% GST to every sale, but agencies typically present quotes ex-GST because the buyer reclaims it on their next Business Activity Statement, so the headline price is the actual cost of the work. If you are comparing quotes from multiple agencies, double-check whether each one is inclusive or exclusive of GST before deciding — a $20,000 ex-GST quote becomes $22,000 inc-GST, and an agency that quotes inc-GST without saying so will look 10% cheaper than one that quotes ex-GST. Asking a single question — 'is this number ex-GST or inc-GST?' — eliminates the confusion. Australian agencies almost always invoice in AUD; international agencies sometimes quote in USD, in which case GST is added on import.

What should you actually budget for in 2026?

Budget by business category, not by feature wishlist. If you are a service business or trade with a single location, budget $5,000–$8,000 AUD ex-GST for a serious custom site with 6–12 suburb pages, schema markup, and call-tracking. If you are a clinic, studio or specialist with multiple practitioners or services, budget $8,000–$15,000 for a content-rich site with booking integration, FAQ, and per-service pages. If you are a DTC or retail brand doing $50,000-plus AUD per month in revenue, budget $15,000–$40,000 on a custom Shopify storefront with PDP CRO work and Australian shipping logic. If you are an enterprise commerce operator needing headless storefronts and bespoke checkout, budget from $40,000 and treat the build as a 3–6 month engagement rather than a 6–10 week one. Across categories, content production (photography, copy, video) is typically 20–30% of total project cost and is almost always quoted separately.

What hidden costs should you ask about up front?

Five categories of cost are frequently missed in initial quotes and turn a $15,000 budget into a $22,000 invoice. Asking about them up front, in writing, is the difference between a project that lands on budget and one that doesn't. The most common cost overruns in Australian agency work trace back to one of these five categories — content production, copywriting scope, ongoing hosting, premium plugin licensing, or maintenance retainers — rather than to the build work itself.

1. Photography and video — most agencies do not include this; budget $2,000–$8,000 separately
2. Copywriting — collaboration is usually included, but a full ghost-write is extra ($1,500–$6,000)
3. Hosting — Vercel/Cloudflare from $0–$200 per month depending on traffic
4. Domain and SSL — under $200 per year for a .com.au plus SSL
5. Premium plugins or apps (Shopify) — typically $30–$300 per month per app
6. Ongoing CRO and content iteration retainers — see maintenance section above
