Top AI Startups In Australia To Watch In 2027

Australia has a growing mix of AI startups working across healthcare, infrastructure, business software and autonomous technology. The National AI Centre counted more than 1,500 AI companies in Australia in 2025, with many focusing on specific industries rather than trying to build general-purpose AI.

This means the sector covers a super wide range of products, from software used by doctors to technology designed for electricity networks and autonomous machines.

Why Is Applied AI So Common In Australia?

A lot of Australian startups are using AI alongside existing industry knowledge. Healthcare is an example, with companies working on everything from medical imaging to clinical documentation. Elsewhere, AI is being used to model electricity networks, handle customer service and support autonomous systems.

What Could Shape Australia’s AI Startup Scene In 2027?

AI agents could become a bigger part of the sector as businesses look for systems that can carry out tasks rather than only answer questions. International expansion could also play a bigger role, with quite a few Australian AI startups already building customer bases outside the country.

As these technologies develop, the focus will be on how well they work in real business and industry settings, rather than what the AI can do in a demonstration.

Sydney-based Harrison.ai develops AI technology for healthcare, with products covering areas such as medical imaging and pathology.

The company says its technology is now deployed at more than 1,000 sites across four continents, with more than 3,400 clinicians using its products. Its technology has also received regulatory clearance in more than 40 countries.

The company has continued expanding overseas during 2026, including the launch of its US-based teleradiology business, Frontier Radiology.

Neara combines AI with physics-based modelling to create digital twins of critical infrastructure. Its platform allows utilities to model their assets and see how they could respond to different conditions before changes are made in the real world.

Neara says its platform has modelled more than 15 million assets across over three million kilometres of networks on four continents. In Australia, it works with close to 90% of network utilities.

With electricity networks dealing with ageing assets, changing energy demands and more complex operating conditions, Neara is using AI to help utilities understand and manage their networks in greater detail.

Relevance AI develops software that allows businesses to build AI agents for tasks such as research, sales, operations and customer support. Rather than using AI only to generate content or answer questions, its platform is designed to help agents complete tasks and interact with business systems.

The company is also building its presence internationally, including in the US. Its focus on AI agents puts it in an area where businesses are looking at ways to automate more complex workflows

Melbourne-founded Heidi Health is another start up that develops AI technology for healthcare. The company initially became known for its AI medical scribe, which helps clinicians create clinical notes, but it has since expanded into other parts of the healthcare workflow.

Heidi says its platform is used across 190 countries and supports around 2.8 million patient visits each week. In September, it also introduced Heidi II, a set of AI agents designed to handle administrative tasks around patient visits while leaving clinicians in control of decisions and approvals.

Lorikeet is an Australian AI startup focused on customer service; its technology is designed to handle complex support requests and take actions across business systems rather than just responding to a customer’s question.

Lorikeet’s approach is built around the idea that AI customer service can handle multi-step tasks, such as checking information, updating an account or resolving an issue across different systems.

That puts the company in another part of the AI agent market, with its technology aimed at tasks that traditionally require a human customer service worker to move between several tools.

Sydney-based Advanced Navigation develops AI and autonomous navigation technology for industries including defence, mining, marine, space and robotics.

The company combines navigation systems with AI, computer vision and robotics to help autonomous systems operate in environments where GPS may be unreliable or unavailable.

The company says more than 100,000 of its systems have been deployed globally, with more than 80% of its revenue coming from the US and Europe. Its technology is used across areas including autonomous vehicles, robotics and other systems that need to navigate without relying entirely on GPS.

Australia’s AI Startups Heading Into 2027

The next stage for these companies will be about turning AI into technology that can be used reliably in day-to-day work. Whether that means supporting a doctor, helping manage an electricity network or carrying out customer service tasks, the real value will come from how well these systems work outside of demonstrations.

As Australian startups continue developing more specialised applications, 2027 could bring more AI products designed around specific industries and the problems they face.
