Here at Casey, one of the most remote and isolated communities on Earth, staying connected is no small feat. Through the depths of winter and the challenges of the Antarctic environment, it’s up to our two-person winter communications team — myself and Darren — to make sure the station stays in touch with the outside world.
At the heart of our work are the satellite links. These provide the internet access that lets us send emails, make video calls, and ring home — a vital lifeline to loved ones and the broader world. As long as the satellite systems are working, life here feels a little closer to home, and that’s why having people on station who can maintain and troubleshoot this equipment is so important.
Satellite links aren’t our only tools. In a place like Antarctica, you need backups and we’ve got some serious radio gear you’re unlikely to find in most workplaces. Some of it looks like it belongs in a Cold War museum, but it’s built to last and still plays a critical role in our communications safety net.
We also look after a wide network of conventional radios and repeaters, spread across vast distances, including sites several hours' drive from station. These systems are essential for field safety and day-to-day operations, especially in harsh or remote locations.
Yes, we even have mobile phones at Casey. and it’s our job to keep the base stations humming along so they stay functional.
Beyond comms, our responsibilities extend into the IT world. We maintain the station's computer network, provide tech support, and generally do our best to fix just about anything with a cable, screen, or blinking light.
Sometimes, we also get involved in projects that most comms techs wouldn’t expect. Recently, we headed out to service automatic cameras monitoring bird nesting sites. These hardy units sit out in the elements year-round, enduring the full force of Antarctic weather. Servicing them takes planning, patience, and a willingness to get cold.
Another weekly task is helping operate the Magnetic Observatory. Because we’re so close to the South Magnetic Pole, we monitor how the Earth’s magnetic field shifts in both direction and strength. For those interested in polar science — or just how a compass works — here’s a quirky fact: at Casey right now, magnetic north and true north are 104 degrees apart. That means if you're using a compass, you’ll be pointing well off from where a GPS would have you go!
During winter, there are no dedicated radio operators on station, so we also handle all aircraft communications. It’s not every day you get to radio through flight clearance to a C-17 or Airbus operating an international mission, but it’s part of the job here.
Working as a comms tech at Casey is never boring. It’s a mix of challenge, variety, and discovery. You’re surrounded by incredible people, working in one of the most unique environments on the planet — and the gear you work with is just as fascinating.
