Mobile App Development Cost in Australia: What Businesses Should Budget For
What drives mobile app development cost in Australia: scope, platforms, backend, integrations, QA, store fees, GST, privacy work and the cost of running an app.
What does a mobile app cost in Australia?
Mobile app development cost in Australia depends on scope, not on a market price. The main drivers are how many user roles, screens and workflows the app has, whether you need iOS and Android, the backend and admin tools, integrations, privacy and security work, and testing. Then add the cost of running the app every year. A priced discovery phase is the most reliable way to get a comparable estimate.
This guide is for founders, product owners and operations leads who need a realistic budget before they talk to developers, or who are trying to compare quotes that look nothing alike. It explains each cost driver, what Australian businesses need to add (GST, store accounts, privacy obligations and accessibility), how to plan an MVP budget, and the questions that expose an incomplete quote.
We deliberately do not publish price ranges. No neutral Australian survey of app development prices exists, and published figures compare apps of very different scope. Where we use numbers, they are labelled as illustrative arithmetic, not market rates. For the generic cost model, see our guide to what drives mobile app development cost. Nothing here is tax or legal advice.
Key takeaways
- Budget the whole lifecycle: discovery, design, build, launch and at least the first year of running costs. Running costs are where most first budgets fall short.
- Scope drives cost more than location or framework. Count user roles, screens, integrations and offline or real-time needs before comparing quotes.
- Cross-platform frameworks often reduce effort for two platforms, but platform-specific features are still built twice. Ask quotes to split shared and per-platform work.
- Apple charges 99 USD a year (in local currency where available) and Google Play a one-time US$25. Both take service fees on digital sales, and Google changed its fee structure for Australian users from 30 September 2026.
- Ask every supplier to state whether 10% GST applies and how quotes show it.
- If you are covered by the Privacy Act, or handle health or children's data, privacy and security work is a line item, not an afterthought.
- Accessibility to WCAG 2.2 AA costs far less when designed in than when retrofitted.
The seven cost drivers, in order of impact
Most of the difference between two app quotes comes from a handful of decisions. In our experience, the order below is roughly the order of impact, though every project differs.
| Driver | What raises cost | What keeps it contained |
|---|---|---|
| 1. Scope and workflows | Many user roles, complex rules, payments, bookings, chat, real-time tracking | One primary user journey for launch; a written list of what is out of scope |
| 2. Platforms | Separate native iOS and Android apps; tablets, watches or web as well | One cross-platform codebase where the feature set suits it |
| 3. Backend and admin | Custom backend, admin portal, reporting, role-based permissions | Managed backend services; a simple admin first; reports added later |
| 4. Integrations | CRM, ERP, Xero or MYOB, payment gateways, legacy systems with poor APIs | Well-documented APIs; one source of truth per record |
| 5. Design | Custom animation, many unique screens, brand-new design system | A component library, platform conventions and a limited screen count |
| 6. Quality, security and privacy | Sensitive data, health or financial information, high availability | Risk-based testing; automated tests on core flows; privacy designed in |
| 7. Launch and running | Many environments, heavy monitoring, 24/7 support | Support hours that match real usage; monitoring on the flows that matter |
Pro tip
Our recommendation: before asking for quotes, write down the single journey that must work on launch day, such as 'a customer books and pays for a service'. Everything else is a candidate for a later release.
Native or cross-platform: what it does to the budget
You can build two native apps (Swift for iOS, Kotlin for Android), one cross-platform app (commonly Flutter or React Native), or in some cases a progressive web app instead of a store app. Each choice changes both the build cost and the running cost.
Cross-platform development shares most user interface and business logic across iOS and Android, so one team maintains one codebase. That usually lowers effort for a typical business app. It does not remove platform work: push notification set-up, payments, background location, widgets, new OS features and store submissions are still handled per platform, and the framework itself has to be upgraded over time.
Native development costs more for two platforms but can be the better choice when the app depends on the newest platform capabilities, heavy graphics or deep device integration. We compare these trade-offs in native vs cross-platform app development and Flutter vs React Native. If you are unsure whether you need a store app at all, read PWA vs native app first: a well-built web app can be the cheapest way to test demand.
What a complete quote should include
A quote is only comparable if it covers the same work. Use this list to check inclusions and exclusions line by line. If a supplier leaves an item out, ask whether it is excluded, included elsewhere or assumed to be your responsibility.
- Discovery: user research or stakeholder workshops, user journeys, a feature list with priorities, a data model and an integration map.
- UX and UI design: wireframes, a clickable prototype, visual design for each screen and state (empty, loading, error), and accessibility annotations.
- App build: each platform or the shared codebase, with offline behaviour, notifications and deep links if needed.
- Backend: APIs, database, authentication, file storage, background jobs and the hosting set-up.
- Admin tools: the portal your staff use to manage users, content, orders or bookings.
- Integrations: each third-party system named, with who supplies credentials and test environments.
- Testing: device coverage, automated tests on critical flows, accessibility checks and a user acceptance testing period.
- Security and privacy: secure storage, encryption in transit, dependency scanning, a privacy policy input and breach response support.
- Launch: store listings, screenshots, review submission, and handling of rejections.
- Handover: source code in your repositories, documentation, credentials and a walkthrough.
- Post-launch: a warranty period for defects, then a priced maintenance plan.
Australian costs to add to any estimate
Several costs are specific to building and running an app for an Australian business. None are large on their own, but leaving them out is a common reason budgets overrun.
GST. GST is 10% on most taxable supplies, and businesses must register once GST turnover reaches A$75,000 (ATO). Quotes may show prices including or excluding GST, and an overseas supplier may not charge Australian GST at all. Normalise every quote before comparing, and ask your accountant how GST affects you.
Store accounts and fees. Apple's Developer Program annual fee is "99 USD ... in local currency where available" (Apple), and an organisation must be a legal entity with a D-U-N-S number to enrol. Google Play charges a one-time US$25 registration fee (Google). If you sell digital goods or subscriptions in the app, the stores take a service fee: Apple's Small Business Program charges 15% for developers with up to 1 million USD in proceeds (Apple), and Google introduced a new fee structure for users in Australia from 30 September 2026 (Google Play service fees). Physical goods and services, such as a booking or a delivery, are generally paid through your own payment provider instead.
Privacy. Many small businesses with turnover of A$3 million or less are exempt from the Privacy Act, but health service providers and some others are covered regardless of turnover (OAIC). If you are covered, budget for privacy-by-design work, a privacy policy, secure storage and a response plan for the Notifiable Data Breaches scheme. The OAIC received 1,205 breach notifications in 2025, the highest since the scheme began (OAIC).
Children and social features. The social media minimum age rules took effect on 10 December 2025 (eSafety), and the OAIC is developing a Children's Online Privacy Code that must be registered by 10 December 2026 (OAIC). Most business apps are unaffected. If your app has public social features or is likely to be used by children, get advice before scoping, because age assurance, moderation and stricter defaults are significant work.
Accessibility. The Australian Human Rights Commission's guidelines on digital access point organisations to WCAG, and WCAG 2.2 adds criteria such as minimum target size and accessible authentication that affect app design. See website accessibility in Australia for how the Disability Discrimination Act and WCAG fit together.
A budgeting model you can use before talking to suppliers
Rather than starting from a total, build the budget from components. The model below is ours. It will not produce a market price, but it shows which assumptions matter and gives you a structure to compare quotes against.
Build budget = Discovery + Design + App build
+ Backend and admin + Integrations
+ Testing + Launch + Contingency
Year-one run = Hosting and services + Store accounts
+ Monitoring tools + Maintenance hours
+ Support hours + Security reviews
Two-year view = Build budget + 2 x Year-one run
+ Planned feature releasesIllustrative example: reading a quote with the model
This example is hypothetical arithmetic, not a market rate. A Brisbane physiotherapy group wants an app for clients to book sessions, pay a deposit and receive exercise programs. A supplier quotes 150 person-days for the build. To make the arithmetic easy, assume a blended rate of A$1,000 per person-day, excluding GST. That gives A$150,000 excluding GST, or A$165,000 including 10% GST if the supplier charges it.
Now apply the model. The quote covers app build, backend and testing, but lists discovery, the clinic admin portal and post-launch support as exclusions. The group is a health service provider, so it is covered by the Privacy Act regardless of turnover, which means privacy design and breach response planning must be added. Exercise videos need hosting and streaming. Three integrations are named: the practice management system, a payment provider and an SMS service.
The useful output is not a total. It is a list of questions: Who builds the admin portal, and for how many days? Does the practice management system have a documented API and a test environment? What does the supplier charge per month for maintenance after the warranty? Once those answers are in writing, the same model applied to every quote shows which supplier has priced the full job.
Worth noting
If a supplier will not list exclusions or explain how they reached their estimate, treat the total as unreliable, however attractive it looks.
MVP budget versus full product budget
An MVP is the smallest product that tests your riskiest assumption with real users. It is not a cheap version of the full product. For an app, an MVP budget usually funds one platform or one cross-platform codebase, one core journey, a minimal admin, essential analytics and enough testing that early users trust it.
Plan the MVP and the full product as two budgets with a decision point between them. Decide in advance what evidence would justify the next stage: a retention rate, a number of completed bookings or a willingness to pay. Our guide to MVP development for Australian startups covers how to choose that evidence, and how long an app takes to build covers realistic schedules.
| MVP budget | Full product budget | |
|---|---|---|
| Goal | Learn whether the core idea works | Serve a known market reliably |
| Platforms | Often one codebase, sometimes one platform | Both platforms; sometimes tablet or web |
| Features | One core journey | Secondary journeys, personalisation, offline |
| Admin | Minimal, sometimes manual processes behind the scenes | Full admin, reporting and roles |
| Testing | Core flows on a defined device set | Broader devices, automation, performance |
| Run costs | Low usage, limited support hours | Scaled hosting, monitoring and support |
The cost of running an app after launch
An app is never finished. Apple and Google update their operating systems every year, and store rules change on fixed deadlines. For example, apps uploaded to App Store Connect since 28 April 2026 must be built with Xcode 26 and the iOS 26 SDK (Apple), and from 31 August 2026 new Android apps and updates must target Android 16, API level 36 (Android Developers). An app that is not updated eventually cannot be updated at all without catch-up work.
Running costs include hosting and third-party services, store accounts, monitoring and crash reporting, dependency and security updates, bug fixes, support hours, and the business time spent on content and customer questions. Our guide to mobile app maintenance lists what a maintenance plan should cover, and crash reporting and monitoring explains the tooling.
Support hours and time zones. If your supplier is overseas, agree support hours in writing. Sydney and Melbourne are 4.5 hours ahead of India during AEST and 5.5 hours during AEDT, Brisbane is always 4.5 hours ahead, and Perth is 2.5 hours ahead. That gives a useful overlap during the Australian working day, but out-of-hours incident cover has to be explicitly priced, whoever the supplier is.
How to keep the budget under control
- Pay for discovery as a separate, fixed-price phase, then request build estimates against its outputs.
- Prioritise features as must, should and could, and defer every 'could' until after launch data arrives.
- Agree a change request process with a day rate and approval step before work starts.
- Hold a contingency, commonly 10 to 20% in our practice, and track what consumes it.
- Use platform conventions and an existing component library instead of designing every control from scratch.
- Confirm integration access early. A missing API or test environment is a frequent cause of delay.
- Review progress on working software every one or two weeks, not on status reports.
- Keep repositories, store accounts and cloud accounts in your business's name from day one.
Common budgeting mistakes
- Comparing a fixed-price quote with a time-and-materials estimate as if they carried the same risk.
- Budgeting the build and nothing for the first year of running costs.
- Assuming a cross-platform app halves every cost line, including testing and store work.
- Leaving the admin portal out of scope, then discovering staff need one to operate the app.
- Treating privacy, security and accessibility as optional extras.
- Letting the supplier hold the Apple or Google developer account in their own name.
- Choosing on day rate alone. A lower rate on a longer estimate can cost more.
Where this fits with your other decisions
Cost is one input into a wider set of decisions. If you are choosing a supplier, read how to choose a mobile app development company in Australia. If the app is part of a broader product, digital product development in Australia covers stage gates and evidence. For the backend and integrations, see mobile app backend development and API integration for Australian businesses. And for security, mobile app security best practices explains what to require.

Conclusion
A realistic mobile app budget in Australia is built from components: discovery, design, build, backend, integrations, testing and launch, plus the cost of running the app every year. Add GST, store accounts and fees, and any privacy, children's safety or accessibility work your app needs. Then compare quotes line by line rather than by total.
The cheapest path to a good app is usually a narrower first release, not a lower day rate.

Common questions.
There is no reliable Australian average, because published figures are mostly vendor marketing and compare very different scopes. Cost is driven by the number of user roles and screens, whether you need iOS and Android, the backend and admin tools, integrations, privacy and security work, testing depth and post-launch support. Ask for a priced discovery phase, then compare build quotes against the same written scope, with GST shown the same way.
