Overwatch Technologies, an Australian defence company using AI to monitor oceans, has listed on the Australian Stock Exchange.

Overwatch Technologies, an Australian defence company using artificial intelligence to monitor the oceans, has listed on the Australian Stock Exchange. Founded in August 2025, the company develops intelligence and surveillance technology using autonomous systems, advanced sensors and data analytics to help government and security agencies monitor the seas for military threats and illegal activity.

The technology allows authorities to cover more territory without relying solely on traditional surveillance infrastructure. Chief executive and co-founder Oscar Leslie, who has over 20 years' experience in the Australian defence force including special services and signals, said the ocean is difficult to monitor with conventional assets such as aeroplanes, naval vessels and coast guards.

Mr Leslie told AAP that militaries are increasingly recognising the importance of lower-cost autonomous assets that require fewer human operators. The technology can also be used to monitor shipping vessel safety and detect other dangerous and criminal activities. Mr Leslie cited the example of 2.64 tonnes of cocaine found on beaches in Fiji, noting the difficulty in tracking the vessel that transported it.
