Mobile app development cost in Australia runs from roughly AUD 25,000 for a simple app to well over AUD 300,000 for a complex one, according to two agency guides we read for this article. Where your app lands depends on scope, platforms, backend work, integrations and compliance, not on the number of screens alone. Treat any figure on the internet, including those below, as a starting point for a conversation rather than a quote.

The bigger risk is budgeting only for the build. This guide shows what moves the price, how to build an app development budget from your own feature list, and how to compare two quotes that look nothing alike.

Key Takeaways

Published Australian ranges for mobile app development cost are wide, from about AUD 25,000 for a simple app to AUD 300,000 or more for a complex one, and they come from agency marketing guides, not independent surveys.
Quotes differ by multiples because the hours, the seniority of the team and the assumptions behind the scope differ, so the number alone tells you little.
Budget for the app after launch: one agency guide cites maintenance of about 15 to 20 percent of the build cost each year, plus store fees and hosting.
Build your budget from a ranked feature list, price it in tiers and add a contingency line for the unknowns.
When you compare two quotes, line up the assumptions first and the prices second.

What Is a Realistic Mobile App Development Cost in Australia?

There is no official price list for apps, and the Australian figures we found come from vendors, so they are indicative at best. They are also national figures, not Melbourne-specific ones. Two agency guides that publish ranges in Australian dollars give a feel for the spread.

Simple or basic - Codewave (2025 guide): AUD 30,000 to 80,000; Aalpha (undated guide): AUD 25,000 to 50,000
Medium (logins, payments, dashboards, APIs) - Codewave (2025 guide): AUD 80,000 to 150,000; Aalpha (undated guide): AUD 50,000 to 120,000
Complex or enterprise - Codewave (2025 guide): AUD 150,000 to 300,000+; Aalpha (undated guide): AUD 120,000 to 300,000+

The Codewave Australian cost guide also puts local developer rates at AUD 100 to 150 per hour for junior to mid-level people and AUD 150 to 200 per hour for senior engineers. The two guides agree on the shape and disagree on the edges, as you would expect when nobody shares a definition of "simple".

Why Do App Development Quotes Differ by Multiples?

Quotes differ because a price is hours multiplied by rate, and both numbers vary. A vendor who assumes a thin first release prices fewer hours than one who assumes polished design, admin tools and automated testing. They are pricing different apps from the same one-paragraph brief.

Here is an illustration, not a real quote. Take 600 hours of work. At AUD 100 per hour that is AUD 60,000. At AUD 200 per hour it is AUD 120,000. Now let the second vendor assume 900 hours because they have included testing, an admin panel and store release work. The same idea has produced a two to three times gap before anyone has done anything unreasonable.

What Drives the Cost to Build an App?

Six factors move a budget most. Rank them for your own idea before you brief anyone.

Scope and features

Every feature adds design, build, testing and integration effort. Chat, location tracking, payments and subscriptions are the usual price movers. The Codewave guide makes the same point: defining the core functionality for a first release is the single best way to control spend.

Platforms and approach

Building separate native apps for iOS and Android often roughly doubles the effort, while a cross-platform framework shares one codebase and usually costs less up front, at the price of some device-specific workarounds. Decide on your audience and performance needs, not price alone. Our mobile application work starts with that question.

Backend and integrations

Most business apps are a screen in front of a system: accounts, data, notifications, and links to your CRM, payments or inventory. The backend and each integration are often a larger share of the work than the visible app.

Design, compliance and testing

Custom design takes longer than standard components. If you collect personal information you have privacy obligations under Australian law, and regulated sectors such as health and finance add security and audit work. Testing on real devices and operating system versions takes time too, and cutting it only moves the cost to after launch.

What Does an App Cost After Launch?

An app is not finished when it ships. Operating systems update every year, third-party services change their terms, and security patches keep arriving. A common planning rule from the Cleveroad guide to app maintenance, which attributes it to the Consortium for Information and Software Quality, is to reserve 15 to 20 percent of the original development cost per year. As an illustration, a build of AUD 100,000 would mean AUD 15,000 to 20,000 a year. It is a rule of thumb from a vendor, so treat it as a first estimate and ask your supplier to price it for your app.

Store fees and hosting

Two fixed costs are easy to verify. The Apple Developer Program costs 99 USD per membership year, with prices shown in local currency at enrolment. Google Play charges a one-time registration fee of US$25, as its Play Console help page states. Cloud hosting and third-party service fees are extra and grow with your users. The Codewave guide estimates that store fees, API subscriptions, legal review, hosting and marketing can add 15 to 25 percent to a project budget if they are not planned, though that is a vendor estimate.

How Do You Build an App Development Budget?

You can build a defensible budget in four steps with a spreadsheet.

List every feature you can think of. Write each as a plain sentence, such as "a customer can reschedule a booking".
Sort them into tiers. Must have for launch, should have soon after, nice to have later.
Ask for a price per tier. A vendor who prices the must-haves alone gives you a realistic first release and a menu for the rest.
Add a contingency line. Size it to the number of unknowns, such as an unfamiliar integration or unclear data. Add a separate yearly maintenance line.

Change requests are normal, not a failure. Our post on software project scope creep sets out how to say yes to changes without losing track of what each one costs.

How Do You Compare Two Quotes?

Do not start with the total. Start with what each quote assumes, then compare the totals. Put both quotes side by side and ask these questions of each.

Which features are in the price, and which are listed as "later" or "optional"?
Is it a fixed price, or an estimate with a range? What happens when a change request arrives?
Which platforms are covered, and is the backend and admin side included?
What testing is included, and on which devices and operating system versions?
Who owns the source code, and is handover documentation included?
What does the first year of maintenance cost, and what does it cover?
Who will actually do the work, and at what seniority?

A vendor who cannot answer these plainly is telling you something. A higher quote with clear assumptions is often cheaper than a low one that turns into change requests.

Common Questions About Mobile App Development Cost

1. How much does it cost to build an app in Australia?

Agency guides we read put a simple app at around AUD 25,000 to 80,000, a medium app at AUD 50,000 to 150,000 and a complex app at AUD 120,000 to 300,000 or more. These are vendor estimates, so use them to frame a brief, not to set a final budget.

2. Why is a native app more expensive than a cross-platform app?

Native means building and testing separate iOS and Android apps, which often roughly doubles the effort. Cross-platform frameworks share one codebase, which is cheaper to start with but can need workarounds for device-specific features.

3. How much should I budget for app maintenance each year?

One vendor guide suggests 15 to 20 percent of the original build cost per year, and that is a rule of thumb. Apps with payments, personal data or many integrations usually need more, so ask for a maintenance estimate with your quote.

4. What are the hidden costs of a mobile app?

The usual ones are store fees, cloud hosting, third-party service subscriptions, legal and privacy review, and updates for new operating system versions. Apple charges 99 USD per year and Google Play charges a one-time US$25 registration fee.

5. Is a cheaper app development quote a red flag?

Not by itself, but it deserves questions. Check whether testing, the backend, admin tools, store release and handover are included, because a low price often reflects a smaller scope rather than a better deal.

A Realistic Budget Starts With a Ranked Feature List

The honest answer to "what will it cost" is a range that narrows as your scope does. Rank your features, price them in tiers, include the year after launch and hold a contingency for the unknowns. That budget will hold up against real quotes.

If you have a feature list, even a rough one, send 9Byte a brief and we will respond with a scoped plan that separates the launch build from the later phases.
