Where are you today?
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.
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.

1 of 6
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.

Directus vs Payload CMS: which headless CMS should you choose?
Choose Payload when your product is a Next.js app and your developers want the content model in code. Choose Directus when your content sits in a SQL database, several apps read it and your editors need a no-code studio. Here is how they differ today, licences and hosting included.
How to get a Lovable or AI-built app into the App Store and Google Play
Lovable builds web apps, and Apple and Google turn away apps that are only a website in a shell. Here are the three routes into the stores (or not), what Apple and Google check besides functionality, and the accounts and timing to plan for.
Lovable or a custom build: when to switch, and when not to
Lovable and Bolt are a fast way to find out what to build. Move to a custom build, or bring engineers in alongside, when the app holds data you must protect, needs something the platform will not do, or the business depends on it. Here is how to tell, and what moves when you switch.
