In Australia, a simple-to-mid cross-platform mobile app typically costs AUD 40,000–150,000, and complex apps such as marketplaces, booking platforms with real-time features or apps with heavy integrations usually start around AUD 150,000. Prices vary with scope, team location and how many user types the app serves. Budget extra for GST, hosting and yearly maintenance.
Treat those numbers as a planning guide drawn from the projects and quotes we see, not a price list. Below we break down where the money goes and how Australian businesses can get good value without gambling on the cheapest bid.
What are typical app development costs in Australia?
Most small and mid-sized Australian businesses land between AUD 40k and 150k for a first app. Here's how the main project types compare, all as estimates that depend on scope.
| Project | Typical cost (AUD, estimate) | Typical first-version timeline |
|---|---|---|
| Cross-platform app, simple–mid | $40k–150k | 10–20 weeks |
| Complex app (marketplace, real-time, many integrations) | $150k+ | 4–9 months or more |
| Web app or SaaS MVP | $25k–80k | 8–16 weeks |
| Custom CRM or back office | $30k–150k | Varies with scope |
| AI chatbot trained on your own documents | $15k–60k | Varies with scope |
At the lower end you're looking at one type of user, a core action (book, order, log, track), sign-in, push notifications and a basic admin panel. Moving towards the upper end usually means payments, several user roles, integrations with tools like Xero or your CRM, and richer reporting.
If you're comparing an app against other custom builds, our guide to custom software development costs in Australia uses the same pricing logic for web platforms and internal systems.
Why do Australian quotes vary so much?
The spread comes mainly from team location, scope clarity and how much risk the developer is pricing in. Two quotes for "the same app" are often quoting different apps.
Common reasons for big differences:
- Team location. Fully onshore teams carry Australian salaries and overheads. Offshore and hybrid teams cost less per hour, with trade-offs in time zones and communication.
- Unclear scope. When requirements are vague, careful developers add contingency; others quote low and recover the gap through change requests.
- What's included. Some quotes exclude the admin panel, back end, testing on real devices, store submission or post-launch support.
- Design depth. A polished standard interface costs far less than custom illustration and animation.
- Compliance needs. Health, finance and apps for children involve extra privacy and security work.
Before comparing prices, make sure every quote covers the same feature list and the same deliverables. Otherwise you're comparing guesses.
Onshore, offshore or hybrid: which gives the best value?
Hybrid teams often give Australian businesses the best balance: local accountability with more competitive build costs. The right fit depends on how hands-on you want to be.
| Model | Relative cost | Strengths | Watch out for |
|---|---|---|---|
| Fully onshore agency | Highest | Same time zone, easy face-to-face workshops, local legal recourse | Budget stretches less far |
| Hybrid (local lead, offshore build) | Moderate | Local point of contact with cost efficiency | Check who actually writes and tests the code |
| Offshore agency | Lower | Competitive pricing, often strong technical depth | Time-zone gaps, contract and IP terms, quality varies widely |
| Freelancer | Lowest | Flexible and fast for small jobs | Single point of failure, thin testing and support |
Whichever model you choose, insist on owning the source code, designs and the App Store and Google Play accounts, registered in your business's name.
How do GST and tax incentives affect your budget?
Add 10% GST to quotes from GST-registered Australian suppliers, and ask your accountant whether any development qualifies for tax incentives. Both can change your real cost noticeably.
- GST. Australian quotes may be shown exclusive or inclusive of GST. Confirm which. If you're GST-registered, you can usually claim the GST back as an input tax credit.
- Overseas suppliers. Different GST rules can apply to imported services, so get advice if you're engaging a team outside Australia.
- R&D Tax Incentive. Some software development that involves genuine technical uncertainty may qualify under Australia's R&D Tax Incentive. Many standard business apps won't, so speak to an adviser before counting on it.
What does an app cost to run after launch?
Plan on roughly 15–25% of the original build cost per year for maintenance, plus hosting and third-party fees. On a $100k app, that's around $15k–25k a year.
Ongoing costs typically include:
- Platform updates. Apple and Google release major OS versions every year, and apps need testing and updates to keep working.
- Hosting and services. Cloud servers, databases, file storage, push notifications, SMS and email delivery.
- Store fees. Apple's Developer Program is US$99 a year; Google Play is a one-off US$25 registration.
- Payment commissions. Digital goods and subscriptions sold in-app generally go through Apple's and Google's billing, with commission typically in the 15–30% range. Physical goods and real-world services can usually use Stripe, Square or similar.
- Improvements. Small features and fixes driven by real user feedback.
Apps without a maintenance budget tend to degrade quietly until an OS update breaks something important.
How do privacy obligations affect cost?
If your app collects personal information, you'll need to handle it in line with the Privacy Act 1988 and the Australian Privacy Principles where they apply to you. Designing for privacy early is far cheaper than retrofitting it.
In practice, that means:
- Collecting only the data you genuinely need.
- A clear privacy policy and in-app account deletion, which both app stores now expect for apps with accounts.
- Secure storage and encryption, plus careful handling of health or financial information.
- Knowing where your data is hosted; many Australian businesses prefer Australian cloud regions.
- A plan for responding to data breaches.
Health, NDIS-related and financial apps typically carry the heaviest requirements, and that work shows up in the quote.
What do typical Australian app budgets look like?
Here are three illustrative scenarios, not real clients, to show how scope shapes cost.
- A Brisbane plumbing business wants a staff app for job sheets, photos, customer signatures and timesheets, synced with its accounting software. One user type plus an admin panel and an integration: likely towards the lower-to-middle part of the $40k–150k range.
- A Melbourne gym group wants member bookings, class waitlists, membership payments and push reminders across several locations. Payments, multiple roles and multi-site logic push it into the middle-to-upper part of that range.
- A Sydney startup wants a two-sided marketplace connecting customers with local service providers, with real-time job tracking, in-app chat and payouts. That's a complex app, typically $150k+.
Each could start smaller. The plumber might launch job sheets first and add the accounting sync later; the startup might validate demand with a web-based MVP. Our guide to what an MVP costs in 2026 explains how to scope that first version.
Which questions should you ask before signing?
Ask questions that reveal scope, ownership and support, not just price.
- Does the quote include iOS, Android, the back end, admin panel and store submission?
- Is it fixed price, and what counts as a change request?
- Who owns the code, designs and store accounts?
- How often will I get a test build on my phone?
- Which devices will you test on?
- What does support cost after launch, and what are your response times?
- Who is on the team, and where are they based?

Frequently asked questions
What's the cheapest way to build an app in Australia?
Narrow the scope to one core job, use cross-platform development, and consider a hybrid team. A progressive web app may also meet your needs for the first year at lower cost. Be wary of very low quotes that leave out the back end, testing or support.
Is it cheaper to build only for iPhone first?
With cross-platform frameworks like Flutter or React Native, building for both platforms costs only modestly more than one, mostly in testing and store setup. Launching on a single platform makes most sense when you're building natively or your users are overwhelmingly on one type of device.
How long does it take to build an app in Australia?
A focused first version typically takes 10–20 weeks from discovery to launch. Complex, multi-sided apps commonly take four to nine months. Slow feedback and mid-project feature additions are the usual causes of delay.
Do I need to pay GST on app development?
If your developer is GST-registered in Australia, expect 10% GST on top of an exclusive quote. GST-registered businesses can usually claim it back. Your accountant can confirm the treatment for overseas suppliers.
Can I get a fixed price for my app?
Yes, once the scope is clear. Many developers run a short discovery phase to define features and user flows, then quote a fixed price for the build. That protects you from open-ended hourly bills.
