Cathy Savei, a determined ni-Vanuatu woman from Ambrym Island, and Joshua Ernst, a professional diver and businessman from Australia have turned a competition into a collaboration. Together, through Big Blue Dive Vanuatu, they are not only shaping scuba divers, but driving marine conservation in the country. This is their story.

Cathy

At 27 years old, I work as the Operations Manager at Big Blue Vanuatu, where I oversee daily operations and ensure everything runs smoothly.

Beyond operations, I’m also a scuba diving instructor. I teach people how to dive, from beginners taking their first breath underwater to advanced divers building their skills, and it’s something I once only dreamed of doing. But I only got to where I am from meeting Josh.

Josh

I’ve called Vanuatu home for most of my life. I arrived here at just two weeks old in 1986 and grew up here before moving to Australia in 1998 to complete my education and begin my career.

I returned in 2013, drawn back not just by opportunity but by a deep connection to the place I’ve always considered home. My family’s roots here date back to the post-independence years, with my uncle, Joe Ernst, in farming, and my father, Roy Ernst, contributing to Port Vila’s restaurant scene, starting with the Waterfront before redesigning and running Rossi Restaurant.

Diving, which began as a hobby, eventually led me to leave my previous profession and pursue what I love. Today, I’m proud to be the owner of Big Blue, with Cathy leading operations by my side.

Cathy

I always wanted to scuba dive, but I didn’t have the money to pursue it. That changed when I was introduced to a scholarship opportunity under the Professional Association of Diving Instructors by a friend. I took a leap of faith and left my catering job to join the dive industry.

From there, everything moved quickly. I went from learning how to dive at Big Blue Vanuatu to becoming an instructor in 2024, and now I manage operations. It wasn’t planned, but it feels like I ended up exactly where I was meant to be.

Josh

Diving has always been a part of my life. I was first certified when I was around 15 with Nautilus Watersports Vanuatu, and even though I stepped in and out of it over the years, the ocean always pulled me back.

Eventually, I decided to make a career change and fully commit to diving. That decision led me to Big Blue Vanuatu, where I started working, then managing and eventually had the opportunity to buy the business.

Cathy

When Josh first arrived at Big Blue in 2023, I didn’t think much of it, just another person joining the team.

But over time, especially during our training, we started to interact more. That’s when the competition began.

Josh

At the time, there weren’t many women in the dive industry, so seeing her stand out the way she did was noticeable.

She was strong, direct, and not afraid to speak her mind. There was even a moment early on where she told me off and honestly, that’s when I realised she was a natural leader.

Cathy

We were both going through dive master training at the same time, and it became a constant challenge of who would come out on top. I always won, of course.

Even during our instructor training, we’d compare scores after every session. It didn’t matter what we were doing, we always wanted to know who did better.

Josh

Our rivalry became so obvious that even our course director noticed it. Every task, every skill, we’d push ourselves harder because the other person was there.

There was one moment I was convinced I had done perfectly, only for Cathy to beat me. I couldn’t believe it, and the banter that followed is still one of the funniest memories we share.

Cathy

Now, our roles have changed. Josh runs the business and I handle operations, making sure everything from staffing to schedules is aligned. It’s a lot of responsibility, but I’ve grown into it. And even though we still compete in small ways, we’ve learned how to work together.

One of the things I’m most proud of is bringing local divers back into the water. Diving can be expensive and not everyone has access to it. Together, we’ve worked on making it more accessible, and seeing more local faces in the diving community means a lot to me.

Josh

Cathy is the backbone of Big Blue. Though I might be the one making decisions, she’s the one making sure everything happens – she is the wheels of the operation and I am the driver. Having someone who understands both the diving and the business side gives me confidence. It’s not just about running a company, but building something sustainable.

We’ve also focused heavily on marine conservation. Just recently, we cleaned up nearly 200 kilograms of debris from the ocean and have been tackling crown-of-thorns outbreaks and rehabilitating corals – we’re trying to protect the resource that we rely on. For us, diving isn’t just a business, it’s a responsibility. Without healthy reefs, there is no future for what we do.

Cathy

There have been challenges, especially coming from different backgrounds. Sometimes I struggle with communication or certain situations, and I lean on Josh for support. Having someone who listens and helps without judgment has made a big difference in how I’ve grown, both personally and professionally.

We are like brother and sister. We argue, we compete, we don’t always agree but we trust each other. At the end of the day, we know we’re working toward the same goal, and that’s what keeps us moving forward.

Josh

One of the biggest challenges Cathy faced was stepping into leadership as a young woman in a male-dominated environment. It wasn’t always easy for others to accept. But she proved herself through her work. I’ve always told her: lead by example, stay consistent and eventually people will follow.

People at work call us Tom and Jerry, and it fits. There’s always banter, always a bit of back-and-forth, but underneath it is a strong partnership. That dynamic is what makes us effective. We challenge each other, and that’s how we improve.

Cathy

There was a time when just having Josh beside me gave me confidence. Even when I couldn’t find the words, I knew I had someone who would support me. That kind of trust is hard to find and it’s something I don’t take for granted.

If there’s one thing I’d want people to take from our story, it’s that if I can do it, others can too. You don’t always start with everything you need, but if you take the opportunity when it comes, it can change your life.

Josh

Watching Cathy lead projects now is inspiring. I can step back, trust her decisions, and know that everything will be handled. Seeing her growth from when we first started to where she is now — it’s something I’m genuinely proud of. She’s a very good mentor for our upcoming ni-Vanuatu divemasters.

For me, it’s about teamwork and trust. We got to where we are because we supported each other and recognised each other’s strengths.

Cathy

We’re both proud to continue creating space for local people to grow into leadership. What we’ve built works because of trust and a shared passion for the ocean, and the more we continue with that, the stronger Big Blue – as a business and a representative of our community – will become.
