Tested in the bay
we call home.
We're not just close to the ocean — we're surrounded by one of Australia's most active cetacean habitats. Humpback whales migrate through Port Stephens every season. Resident bottlenose dolphin pods are in the bay year-round. We build tools for underwater listening because it's part of where we live and what we care about.
