She heard about the job on morning television. Eight months later, she was standing on the ice at the bottom of the world.

Sara Pearce spent fifteen years learning how buildings live and die before a question on morning TV sent her south. Now she runs engineering at Australia's Antarctic stations, where one cracked pipe can cost a year's worth of water and a leaking toilet is never just that.

The question arrived on a Tuesday morning while Sara Pearce was getting ready for work.

She was standing in her kitchen, half-dressed, half-listening to the television, when a segment cut through the noise with a question that was blunt and almost daring.

"Are you crazy enough to take on a job in Antarctica?"

She stood there for a moment having already worked in nearly every state and territory in Australia.

She had done the design work, the project management, the construction sites, the long drives to places most people only ever fly over.

"I thought...maybe?" Sara said.

So she looked up the Australian Antarctic Division's website, applied and got through on her first attempt.

"I can't believe this is real."

Months later, when she stepped off the helicopter onto the ice at Davis Station, a forty-five second flight from ship to shore, and looked out at a world so white and still it seemed impossible.

She turned to a crew member and asked them to pass a message to her boss back in Australia.

"Thank him for choosing me."

Then she picked up her bag and went to work.

That was in 2017. Now, Sara Pearce is the Director of Engineering at the Australian Antarctic Division, a role created specifically to formalise the thing the program had always depended on - engineers who can see the whole picture, think across the full life of a system, and stay steady when the window to fix something is closing fast.

Sara always knew she wanted to be an engineer.

During school she would spend hours in the library pulling oversized architecture books from the shelves, absorbed by the lines of tall buildings, the logic of structure and form.

Her older brother did technical drawing at school and she used to watch him sketch plans, thinking 'I want to do that'.

She did work experience with an architect as a teenager and came away with a realisation that shaped everything that followed.

Not every project needs an architect. But every project needs an engineer.

After high school she completed a Diploma of Structural Engineering at TAFE, took a gap year to teach English in China, came back certain she was not cut out to be a teacher, and finished her engineering degree at UTS in 2005.

She then joined a design and construct company and stayed for fifteen years, a continuity that's rare in any industry now.

It gave her something most engineers spend entire careers trying to assemble, the ability to see a project all the way through, from the first line on paper to the moment it stands on its own.

She started as a design engineer, then became a project engineer, then a project manager, a construction manager, a design manager.

She saw how decisions made at a drawing board played out on a construction site three years later.

She saw what worked and what didn't, and she carried all of it with her when she left.

"All of that set me up for this role," she said. "I've seen the full life cycle. I think that's what enabled me to take it on in its current format."

The Australian Antarctic Program operates three stations on the continent, Casey, Davis and Mawson, and one sub-Antarctic station on Macquarie Island.

Sara describes each of them as a miniature city.

Her team produces water, generates electricity, maintains heating and lighting systems, and keeps every piece of infrastructure running to the same standard expected in Australia, in conditions that make every task harder, slower, and more consequential than it would be anywhere else.

The work sits inside something larger. Australia's Antarctic program is not just logistically complex. It is essential to the science happening at those stations, research into ice cores, climate systems, and the biological life of the Southern Ocean, work that has never mattered more than it does right now.

The infrastructure Sara's team maintains is the foundation on which that research depends.

At Davis Station, there is no natural freshwater source.

The team extracts water from a hypersaline lake using a reverse osmosis unit that can only operate for eight to twelve weeks a year.

There is one window.

One chance to produce enough water for the entire year.

If something fails during that period, the team has to diagnose it, fix it, and get it back online before the opportunity closes. The water then goes into insulated tanks with internal heating loops circulating warm water to stop it from freezing.

"You lose ten thousand litres of water with a toilet that has a small leak nobody has noticed," Sara said.

"In Antarctica, a leaking toilet is never just a leaking toilet."

Her most significant recent work came during the 2023 to 2024 season, when she returned for a full Antarctic winter, an experience few people in the world have had. She spent the summer at Mawson Station, leading the early works on the Mawson Bollard, a new mooring point for the program's research vessel. The project required moving a drilling rig across sea ice to a remote stretch of land before the ice melted, leaving the equipment there for several months, and returning when the weather held long enough to drill into rock that had not been touched in forty years.

She says the work was not technically glamorous, but it was deeply satisfying.

She then moved to Davis Station for the winter portion of her season, managing a renovation inside an existing building. Converting shared rooms to single-occupancy quarters sounds ordinary until you understand what ordinary means at the bottom of the world. Some materials had to be kept warm. Others had to be unpacked from shipping containers on the rare days when the weather held and repacked before the temperature dropped again. At one point, twelve people lined up to carry sheets of plasterboard, one at a time, through the building's doors, because nothing could be left outside. And because the building was forty years old, the drawings did not match reality.

Things had been changed over the decades and not tracked.

You would look at a wall, then look at the plans, and try to piece together what had happened and when.

She described it, with a dry warmth, as an Antarctic edition of 'The Block.'

"You find things that are not as they should be," she said. "And you're always trying to put the pieces of the puzzle together."

Leadership in Antarctica, Sara said, is collaborative by necessity.

She says the environment makes ego a liability.

Everyone has a role to play: the engineer, the chef, the communications technician, the person who knows what a forty-year-old building actually looks like on the inside.

Leave any one of them out and the problem gets harder.

"The more people you bring together, the more resilient you become," she said.

"Sometimes they see something you don't, because it's not quite your skill set."

She spoke about being a woman in engineering over more than two decades with the calm of someone who has thought about it for a long time and arrived somewhere clear.

When she started, the industry was heavily male-dominated. There is more representation now.

But not enough, and she does not think the rate of change is sufficient.

What interests her more than the external barriers, though, is the internal ones.

For years, she said, women did not apply for roles unless they could tick every single box on the criteria. Men applied anyway. She has watched that pattern play out across her career and wonders sometimes whether what holds women back is not always a ceiling above them but a doubt inside them.

"I wonder how much we still think there is a glass ceiling," she said, "in exactly the same manner, when maybe the thinking has moved."

Her generation of women sits in an unusual position, she said.

"They grew up before social media and have had to adapt to a world that moves faster than anything they were trained for. That makes them a bridge between two very different ways of working and thinking."

She sees it as a strength and thinks that position comes with a responsibility: to use what they know to make the next generation of women feel that what is possible is wider than it might appear.

"We've broken a lot of glass ceilings that were certainly in place," she said. "But we've got way more progress to make. And we need to use where we are to inspire people to keep going."

"Antarctica definitely changes you," Sara said.

"It teaches patience and humility, and it teaches you something about the particular satisfaction of a system that works exactly as it should in conditions that should make it impossible."

Sara refers to her relationship with Antarctica like a toxic ex.

"Antarctica gets under your skin in a way that I've never quite been able to put into language."

Because she still has the visual memory of walking off that helicopter, forty-five seconds from ship to shore, and looking out at a world so white and still it did not seem real.

"It's a reminder of what is possible when human determination meets the power of nature."

She picked up that possibility on a Tuesday morning, half-dressed, watching television and she's been carrying it ever since.
