App developers in Sydney and Melbourne: Digital products built to scale.
Human-led, AI-accelerated.
Rocket Lab Australia is a team of app developers in Sydney and Melbourne. Since 2014, founders and brands like Webjet, Petbarn and Superloop have trusted us to design, build and run their products. Now we help teams ship faster with AI, without the mess.
Products we have helped build, launch and scale.
Where are you today?
Founders building something new
From idea to launched product. We design and build MVPs properly the first time, so you don’t pay for a rebuild later.
Apps built with AI
Built with Lovable, Claude Code or Cursor and not sure it’s ready? We tell you what to fix, what to cut and what it costs to launch.
Teams running products that matter
Senior engineers who plug into your team, modernise safely and keep business-critical platforms improving for years.
Government and regulated industries
Careful, well-documented delivery for sectors where accuracy and security matter.
What value we bring to the table
Strategy, design and senior engineering for products that have to work on launch day and for years after.

We map out the systems, integrations and infrastructure needed for scalability, performance and security.
Agile Build
Our Australian-based team delivers in iterative sprints with regular demos so you can see progress and provide feedback.
QA & Launch

1 of 7
We partnered with Rocket Lab to reimagine our digital experiences, and they delivered with strategic clarity and engineering excellence.
We have a long standing partnership with Rocket Lab who provide Webjet with critical strategic and development services for our front-end websites.
Over the years Rocket Lab have seamlessly integrated with James Hardie in delivering a number of key projects for the business that to this day continue to be critical to the success and functionality of our operations.
When it comes to out-sourcing and partnering with a technology vendor, Rocket Lab is top of mind. Julien, Jen and the team are incredibly detailed and thorough whenever they’re engaged in a project. And, they do so at velocity.
Rocket Lab’s ability to help define and execute our business through software in a timely fashion, has been a breath of fresh air and a pleasure to work with.
The guys worked together very well with our internal resources and blended into our process seamlessly. We were very impressed with the level of skill from each of the engineers…
Our business has hundreds of suppliers and thousands of customers so we needed a highly robust structure and that’s exactly what was delivered by Julien, Jen and the RL development team.
Frequently asked questions
How much does mobile app development cost?
It depends on scope, platforms, integrations and how much already exists. We recommend a short discovery phase first. It defines the user flows, design and architecture, so the quote is based on evidence rather than a guess.
How long does it take to build a mobile or web application?
A focused first release usually takes 2 to 3 months, a medium-sized product 4 to 6 months and a larger platform 6 months or more. Discovery confirms the timeline before the build starts.
What makes Rocket Lab different from other web & app development companies?
Senior people do the work. You deal directly with the designers and engineers building your product in Sydney and Melbourne, not an account manager. We have built and run business-critical web and mobile products since 2014, and we use AI to move faster.
Is your team based in Australia?
Yes. Our team works from Sydney and Melbourne.
Can you take over or fix an app built by another team or with AI tools?
Yes. For apps built with tools like Lovable, Cursor or Claude Code, the App Rescue Report tells you what to fix, what to cut and what it costs to launch. For larger products we start with a technical review, then modernise or rebuild only what needs it, with ongoing support and optimisation after launch.
Is Rocket Lab Australia related to Rocket Lab USA?
No. Rocket Lab Australia is an independent app development company in Sydney and Melbourne, not affiliated with Rocket Lab USA, the space company.

Agentic AI in Practice: Real Workflows, Real Guardrails
It's one thing to talk about agentic AI in the abstract. It's another to actually run one in a live workflow, where a mistake has real consequences. Here's what that looks like in practice.
Setting Up AI Agents for Mobile App Development: A Practical Starting Point
Bringing AI agents into a mobile development workflow sounds like a big technical lift, but the teams that do it successfully usually start smaller and more deliberately than you'd expect.
The Nuances of AI Prototyping
AI prototyping tools have made it possible to go from an idea to something clickable in minutes rather than days. That speed is genuinely useful, but it changes the nature of client conversations in ways worth being deliberate about.
