Freediving fears: 12 “what ifs” our Sydney students ask, answered honestly

So we went through our inbox and the questions on our course pages, and pulled out the freediving fears that come up most. Our team teaches nervous beginners in Sydney every weekend, so we’ll give it to you straight.

Some fears come from myths. Others point to real risks, and we’ll show you exactly how we manage them.

Is freediving scary for beginners?

Freediving feels scary for most beginners before they start, and that’s completely normal. The fear usually comes from not knowing what to expect. On a good course, you start on land, practise in a pool, then dive in sheltered open water on a guideline beside your instructor. You set the pace and can stop any time.

In other words, feeling nervous doesn’t mean freediving isn’t for you. It usually just means you haven’t tried it yet. Let’s go through the “what ifs” one at a time.

1. “What if I can’t see the bottom?”

This is the one we hear most. You look down, see nothing but blue, and your brain fills the gap with every scene from Jaws.

Here’s the thing. On a course, you never swim down into nothing. We set up a floating buoy with a guideline running straight down from it. You hold the line, follow it with your hands and come back up the same way.

Some days you’ll see the reef below you. Other days you won’t, and that’s when the line does its job. It gives your eyes and hands something to focus on.

Most importantly, you’re never alone down there. One of our instructors is with you on every single dive, the whole way down and the whole way up. At no point during the course will you be underwater by yourself.

That’s a really nice thing to have. You feel safe, your confidence builds faster, and you get someone to share the experience with.

You also control the depth. Your first dives stay shallow, and you only go deeper when your body feels ready. Nobody sends you to 20 metres on your first breath hold.

2. “What about sharks?”

We won’t pretend sharks don’t exist. The shark incidents around Sydney in January 2026 hit our whole community hard, and it’s natural to have them on your mind.

It helps to look at the numbers. Taronga’s Australian Shark Incident Database records an average of 27 injury incidents a year across Australia. That’s in a country where 16 million people visit the coast several times a month.

The risk isn’t zero, so we manage it. We follow the NSW Government’s SharkSmart advice for every ocean session:

• We don’t dive in murky water, especially after heavy rain.
• We take extra care near river mouths and harbours after rain.
• We avoid the water at dawn and dusk.
• We watch for baitfish, diving birds and other signs of feeding activity.

If conditions aren’t right, we change sites or reschedule. We’d much rather lose a day than take a chance.

The sharks you’re most likely to meet on a Sydney dive are Port Jackson sharks and wobbegongs resting on the reef. Both show little interest in people, and plenty of divers go looking for them. Meet some of the marine life you might see while freediving.

Freedivers also keep a low profile underwater. We don’t blow bubbles, we move slowly, and we spend most of our time watching quietly.

3. “Do I have to wear a wetsuit?”

For the ocean day, yes, and you’ll be glad of it. Three worries usually sit behind this question: warmth, fit and how you’ll look.

Warmth first. Sydney water feels cool for much of the year, and cold makes you tense. Tension burns oxygen fast. A good wetsuit keeps you warm enough to relax, and relaxing lengthens your breath hold.

It also helps you float. That extra buoyancy lets you lie still at the surface and breathe calmly between dives, rather than working hard to stay up.

As for how you look, everyone in the water wears the same thing. Nobody on a freediving course checks out anyone else’s neoprene. They’re all too busy thinking about their own first dive.

You don’t need to buy one. Your course fee covers all your equipment, including the wetsuit. Just tell us your size before the course so your instructor brings the right one.

4. “How far out into the ocean do you go?”

Not as far as you might think. Our Sydney open water sessions run from sheltered spots like Gordons Bay in the Eastern Suburbs. When the swell picks up, we move to calmer water such as The Spit in Mosman.

You enter from the shore and swim a short distance to the buoy. You won’t head offshore into the open ocean.

On our Central Coast course, day two includes a boat dive to the HMAS Adelaide shipwreck off Terrigal. Wherever you train, your instructor is in the water with you for every dive.

5. “What if I’m not a strong swimmer?”

You don’t need to be fast, and you don’t need a swim squad background. You do need to feel comfortable in the water.

For our Level 1 course, you should be able to:

• Swim at least 100 metres unassisted in a pool.
• Get in and out of the ocean on your own.
• Float, swim and follow instructions calmly in an ocean environment.

Fins do a lot of the work in freediving, and good technique matters far more than speed. If you’re unsure whether you meet that standard, start in the pool.

Not quite ready for the ocean? Our Try Freediving course is a one-day, pool-based introduction. You’ll learn breathing, breath holds and safety skills in a calm, controlled setting. Love it? Upgrade to the full Level 1 course afterwards. Book your Try Freediving day.

6. “What if I can’t hold my breath for very long?”

Almost nobody can at the start, and it doesn’t matter. Freediving has far more to do with relaxation than lung size or fitness.

The urge to breathe comes mainly from rising carbon dioxide, not from running out of oxygen. Once you understand that feeling, it stops being scary. It becomes a signal you can read.

Your body helps you, too. When your face meets cool water, the mammalian diving response slows your heart rate and conserves oxygen. Our breathing and relaxation work builds on that natural reflex.

By the end of our one-day Try Freediving course, most people comfortably hold their breath for around 1 minute 30 seconds to 2 minutes. Our instructors keep every breath hold well within your comfort zone.

At Freediving Central, we only promote breath holds that feel good. If you’re pushing, you’re doing too much.

It’s all about building positive thought patterns around breath holding. That way, your freediving journey starts the right way and can grow into a lifelong hobby, sport and passion.

7. “What if my ears hurt?”

Ear discomfort is the most common hurdle for new freedivers, and you can learn to fix it. It happens when the pressure behind your eardrum doesn’t match the water pressure around you.

Divers Alert Network lists middle-ear barotrauma as the most common diving injury. Poor technique, congestion or descending too fast usually cause it. That’s why we teach equalisation before you go anywhere near depth.

On the course, you’ll learn to:

• Equalise early and often, starting at the surface.
• Use Frenzel equalisation, the technique most freedivers rely on.
• Stop, come up a little and try again if your ears won’t clear.
• Skip diving when you have a cold or blocked sinuses.

Want a head start? Watch our free equalisation video before the course. If your ears are an ongoing struggle, our equalisation course focuses on nothing else.

8. “What if my technique is no good?”

Then you’re exactly who the course is for. Nobody arrives with good technique. That’s the whole point of learning.

Day one starts on land with safety, breathing, relaxation and equalisation. Then we head to the pool and practise it all in calm, clear water. You’ll swim underwater for distance and learn buddy rescue skills.

Day two moves into open water. Progression is individual, so you work at your own pace. Your instructor fine-tunes small things as you go, one dive at a time.

9. “What if people are watching me?”

Honestly? Someone will be watching you. That’s the whole safety system.

In freediving, you never dive alone. Your freediving buddy watches every dive, and you watch theirs. It isn’t judgement. It’s how we keep each other safe.

Everyone else in the group is a beginner too, nervous about the same things you are. Our small groups also mean nobody gets lost in a crowd.

Plenty of people book with a friend or partner to make it easier. You can also bring a whole group, and we’ll help you plan the day. Most people leave with new dive buddies, not embarrassing stories.

10. “What if I panic underwater?”

This fear makes sense. Holding your breath with your face in the water feels unnatural at first.

Two things help. First, you’re always in control. You can turn around at any moment, for any reason, and your instructor will be right there.

Second, calm is a skill. We teach you breathing and relaxation techniques before you dive, so you have tools for that rising-panic moment.

Many of our students arrive a little nervous. Most leave feeling calm, capable and connected. Our post on freediving for meditation explains why the water has that effect.

11. “What if something goes wrong?”

Freediving carries real risks, and the biggest is blackout from low oxygen. We won’t gloss over that. We teach you about it because understanding it keeps you safe.

Here’s how we manage risk on every course:

• You never dive without a trained buddy watching.
• You learn buddy rescue skills in the pool on day one.
• Qualified instructors supervise every session.
• We keep dives well within your comfort zone and never push you past it.

Every student completes a medical form before the course. You only need a doctor’s sign-off if you tick “yes” to a medical condition.

Read more in our guide to freediving safety and emergencies.

12. “What if the weather’s bad on the day?”

Freediving is an outdoor sport, so the ocean sets the schedule. Our team checks the swell, wind and water conditions before every open water session.

If the day can’t go ahead safely, we’ll let you know through your course WhatsApp group before you leave home. Then we’ll reschedule. You have 12 months from your booking date to complete your dives, so you won’t miss out.

For us, it’s never about pushing people through. It’s about making sure you experience freediving in its purest form. If conditions aren’t right, we’ll reschedule and make sure you get the experience you deserve.

Why I take your “what ifs” seriously

I’ve spent more than 12 years freediving professionally. My background is in big wave surfing, and the ocean taught me early that respect and fear are two very different things.

I served as National Geographic’s head safety diving consultant on the 2021 Disney+ series Secrets of the Whales, working alongside filmmaker Brian Skerry. My job was to provide safety in remote locations and challenging conditions.

I bring that same thinking to every beginner course we run in Sydney. The planning that protects a film crew also protects you on your first ocean dive.

I’ve also put years into the skills beginners worry about most. Today I’m Australia’s deepest hands-free equalisation freediver at 62 metres. Believe me, ears, breath holds and nerves are all trainable.

Here’s what I tell every nervous student. Fear isn’t a stop sign. It’s information. You don’t need it gone before you start. You just need it smaller than your curiosity I started my own freediving journey. Stuck on the what-ifs too. I was so nervous that I began as a feet-first free diver going down the line upright. Those nerves fed straight into my equalization, and my ears wouldn’t clear. If I could get from there to here, your starting point is fine.

Your “what if” is probably on this list

Every confident freediver once stood on the shore with the same questions. Nervous, curious and a little unsure is the perfect place to start.
