Mobile App Development for Australian Businesses

iOS and Android apps built for Australian users, payments and privacy rules, by an India-based team that overlaps with your afternoon.

Mobile App Development for Australia

Mobile App Development, built around how Australia works

Australians use apps for banking, food delivery, trades bookings and government services, and they expect tap-to-pay wallets, fast sign-in and clear privacy choices. Nexzem builds native and cross-platform apps for Australian businesses from India. The time difference works in your favor: feedback you give in your afternoon is often built and on TestFlight by your next morning. See how we work with Australian clients.

Australian apps have their own checklist: personal information handled under the Australian Privacy Principles, payments that include PayID, eftpos and Afterpay, health apps that may fall under TGA medical device rules and, for social features, minimum age requirements. Each is covered below, along with how we choose between Flutter and React Native.

Privacy and age rules for Australian apps

Apps run by APP entities need a clear privacy policy, collection notices at the point data is gathered and consent for sensitive information such as health or biometric data. If the backend or analytics sit overseas, APP 8 applies to that disclosure. We host in AWS Sydney or Melbourne where possible, keep analytics configurable and avoid collecting data the app does not need.

Platforms covered by the Online Safety Amendment (Social Media Minimum Age) Act 2024 must take reasonable steps to stop under-16s holding accounts. Whether your app is covered depends on its features and any exemptions, so we design sign-up flows that can add age assurance if your advisers say it is needed. This is general information, not legal advice.

Payments Australians expect

Contactless and mobile wallet payments are everyday habits in Australia, so Apple Pay and Google Pay are expected wherever an app takes cards. PayTo lets customers authorize recurring payments straight from their bank account, an alternative to traditional direct debit for subscriptions. Typical payment and delivery integrations:

  • Apple Pay and Google Pay through Stripe, Tyro, Square or Adyen
  • PayID and PayTo for account-to-account payments
  • Afterpay and Zip for buy now, pay later
  • Australia Post and Sendle for delivery quotes and labels
  • Address autocomplete with Addressfinder or Google Places, validated against G-NAF data

Health apps and the TGA

Software that diagnoses, monitors or treats a condition can be a medical device regulated by the Therapeutic Goods Administration, and some apps need inclusion in the Australian Register of Therapeutic Goods. Others, including many wellness and consumer health apps, are excluded. We help you write down the app's intended purpose early, since it drives the regulatory path, and build health features such as those in our telemedicine app solution to match.

What our mobile app development covers

Native and cross-platform iOS and Android apps built for real users, from first MVP to scale.

  1. 01

    iOS App Development

    Swift and SwiftUI apps that follow Apple's Human Interface Guidelines, support current iOS releases, and clear App Store review without repeated rejections.

  2. 02

    Android App Development

    Kotlin apps tested across screen sizes and Android versions, tuned for the low-memory devices many of your users in India and abroad still carry.

  3. 03

    Cross-Platform Apps

    One Flutter or React Native codebase for iOS and Android, cutting build and maintenance effort while keeping smooth scrolling, animations and device access.

  4. 04

    MVP Development

    A focused first release with the few features that prove demand, structured so it can grow into the full product without a costly rewrite.

  5. 05

    Offline-First Apps

    Local storage and background sync so field staff, delivery riders and rural users keep working when the network drops, with changes uploaded later.

  6. 06

    Payments and Notifications

    Razorpay, Stripe, in-app purchases and push notifications wired in with proper receipts, retries and opt-in handling that meets each platform's rules.

  7. 07

    App Modernisation

    Rebuild or refactor an ageing app, fix crash hotspots, update the SDKs the stores now require, and migrate users without losing any of their data.

  8. 08

    App Store Launch

    Store listings, screenshots, privacy labels, signing certificates and staged rollouts handled for you, so launch day is not spent fighting review queues.

How a project runs

Clear stages with a review at the end of each, so you always know what happens next and what it costs.

  1. 01

    Discovery and Scope

    We map users, core flows and integrations, then agree a feature list, platform choice and fixed quote.

  2. 02

    Clickable Prototype

    Wireframes become a tappable prototype you can show users and investors before any code is written.

  3. 03

    Sprint Development

    Two-week sprints with a test build each cycle, code review on every change, and automated tests on core flows.

  4. 04

    QA on Real Devices

    Functional, performance and battery testing across a device list that matches your audience.

  5. 05

    Launch and Support

    Store submission, staged rollout, crash monitoring and a support plan for updates and new features.

Mobile App Development in Australia, answered

Something else on your mind? Ask a consultant and get a reply within one business day.

Can our app's data stay in Australia?

Yes. Backends, databases and file storage can run in AWS Sydney or Melbourne, Azure Australia East or Google Cloud Sydney. Some third-party services, such as push notification gateways or certain analytics tools, process data offshore, so we list them for your privacy policy and keep personal information out of what they receive.

Can an Australian startup start small?

Yes. Many start with a cross-platform MVP covering one core journey, then add features once real users are on it. Our app cost calculator gives a rough range, and MVP development explains how scope is cut without creating rework later. Invoicing in AUD can be discussed.

Can the app connect to Xero or MYOB?

Yes. Field service, trades and booking apps often create invoices or quotes in Xero or MYOB directly from a completed job, with payments reconciled automatically. We use their official APIs with OAuth 2.0 and handle token refresh and rate limits so the sync keeps running quietly in the background.
