How much does an app cost to build in Australia?

Ask five Australian developers what your app will cost and you will get five numbers spanning $10,000 to $250,000, for the same idea. None of them are necessarily lying. This guide explains why the spread exists, where real projects actually land, and the decisions that decide whether you end up at the cheap end or the eye-watering one.

The short answer

In Australia in 2026, a focused first version of a mobile app typically lands between $15,000 and $50,000. Simple single-purpose apps can come in under that. Apps with marketplaces, real-time features, payments and both iOS and Android native builds go well beyond it. The single biggest cost decision is not the design or the features list, it is the platform strategy.

The platform decision that moves the price most

Progressive web app (PWA)

An app-like experience that runs in the browser and installs to the home screen. One codebase, no app store approval process, instant updates. The most cost-effective way to get an app into users' hands, and for many business apps, all you ever need.

Cross-platform (React Native, Flutter)

One codebase compiled for both iOS and Android app stores. Roughly 60 to 70% of the cost of building two native apps, with near-native feel. The sweet spot for most consumer apps.

Fully native (Swift + Kotlin)

Separate builds per platform. Best performance and platform integration, roughly double the build and double the ongoing maintenance. Justified for demanding apps, overkill for most business tools.

What actually drives app development cost

• →User accounts and roles: login, profiles, permissions, password resets, all foundational but real work
• →Backend and database: almost every useful app needs a server side, often half the total build
• →Payments: Stripe or in-app purchases bring compliance, edge cases and store commission rules
• →Push notifications: deceptively involved across platforms
• →Real-time features: chat, live tracking and live updates add significant complexity
• →Admin dashboard: you will need a way to manage users and content, and it is effectively a second app
• →App store compliance: Apple review, privacy manifests, store assets, resubmissions

Ongoing costs after launch

Budget for hosting and infrastructure (commonly $20 to $200+ a month at small scale), an Apple Developer account (US$99 a year) and Google Play (US$25 once), plus third-party services like SMS or AI APIs if used. OS updates occasionally force maintenance work, more so for native builds than PWAs.

How to launch without burning the budget

Cut the feature list in half, then launch. Version one needs the core loop that makes the app worth opening, nothing else. Many of our clients start with a PWA to prove the idea with real users, then invest in store apps once there is traction. It is also worth being sure you need an app at all, our guide on websites vs web apps covers when a web app does the same job for less.

Getting a real quote

Bring a plain-English description of what a user does in the app, screen by screen if you can sketch it. That single document tightens quotes more than anything else. Book a free 30-minute call and we will scope it honestly, including telling you if a PWA gets you there for a fraction of the price.
