I still remember the first time I spotted dolphins in Perth. I was out for a weekday walk along the South Perth foreshore, minding my own business, when two dolphins cruised past in the Swan River. Middle of the day, hardly anyone around, and there I was just standing there thinking, dolphins… in the river? What??
I watched them surface and disappear again for ages, huge smile firmly stuck on my face. Since then, I’ve learned the river has a few resident dolphins and I’ve been lucky enough to spot them a handful more times. It never gets old. Even now.
That’s the thing about dolphins in Perth. They’re not rare, but they’re never boring. Between sheltered rivers, calm coastal bays, and protected marine environments, Perth is genuinely one of the best places in Western Australia to see wild dolphins going about their day. From surprise sightings along the river, to more reliable encounters around places like Mandurah and Rockingham, dolphins are very much part of our local wildlife scene.
Of course, there’s a big difference between catching a lucky glimpse from shore and actually getting in the water with them. In this guide, I’ll walk you through where you can see dolphins around Perth on your own, when you’re most likely to spot them, and the safest, most ethical way to swim with dolphins if that’s on your bucket list.
Where to See Dolphins in Perth (Without a Tour)
One of the best things about dolphins in Perth is that you don’t actually need to book anything to see them. With a bit of luck, the right conditions and some patience, you can spot wild dolphins from the shore in several spots around the metro area and beyond.
That said, it’s important to go in with realistic expectations. These are wild animals. Some days you’ll see nothing, other days you’ll get a front-row seat to something pretty special.
Swan River
The Swan River is one of the most surprising places to see dolphins in Perth, especially if you’re visiting for the first time. Yes, it’s a river, but it’s also home to a small number of resident bottlenose dolphins that regularly move between the river and the coast.
Good spots to keep an eye out include:
- South Perth foreshore
- Around Elizabeth Quay
- Applecross and Como foreshore walks
Top tip: early morning or late afternoon tends to be best, especially on calm days. I’ve had the most luck when the water is glassy and there’s not much boat traffic.
Sightings here are pretty rare, but when it happens, it feels extra magical precisely because you’re not expecting it.
Mandurah
If you’re after one of the most reliable places to see dolphins in Western Australia, Mandurah is hard to beat. The Mandurah estuary and waterways are well known for their dolphin population and locals will tell you it’s pretty common to see them cruising past jetties or popping up near the foreshore.
Some good places to try:
- Along the Mandurah foreshore walk
- Near the bridges and marina areas
- Quiet estuary spots early in the day
Mandurah is a great option if you want to maximise your chances without committing to a tour, especially if you’re already planning a day trip south of Perth.
Rockingham and the Perth South Coast
The calm, sheltered waters around Rockingham are another hotspot for dolphin sightings. This area is home to a large local dolphin population and is one of the reasons Rockingham is often mentioned when people talk about dolphin encounters near Perth.
You’ll sometimes spot dolphins:
- From beaches on calm days
- Near jetties and boat ramps
- While walking along the foreshore
Because this coastline is more protected than Perth’s open beaches, conditions are often better for spotting marine life close to shore.

Can You Swim with Dolphins in Perth?
Short answer: yes, but only in very specific, regulated settings.
The dolphins you see around Perth are wild animals. They’re not trained, fed, or used to human interaction, which means swimming up to dolphins you spot from shore or a boat isn’t advised and can be illegal in some areas. It can stress the animals and put people at risk.
You might occasionally see dolphins swim near paddleboarders or surfers, especially in calm bays. Those moments are completely on the dolphins’ terms, and it’s important to let them come and go without following or trying to interact.
That’s why structured dolphin swim experiences exist in Western Australia. They’re designed to keep encounters dolphin-led, follow strict wildlife guidelines and protect both people and animals.

How to Swim With Dolphins in Perth
If swimming with dolphins is high on your list, the most reliable option near Perth is the Swim with Wild Dolphins Tour that runs out of Rockingham, around 50 minutes south of the CBD.
This area is home to a population of bottlenose dolphins, which is why it’s widely considered one of the best places in Western Australia for ethical dolphin swim experiences.
On the day, you can expect:
- A small group on a purpose-built dolphin swim boat
- A clear safety and wildlife briefing
- Snorkelling instruction before entering the water, no prior experience needed
- Wetsuits and snorkelling gear provided
- Dolphins choosing if and how they interact
The crew only enters the water when conditions and dolphin behaviour are right, which helps protect the animals and improves the quality of the encounter.

Spotting dolphins from shore is always a bonus, but it’s unpredictable. This day trip is built around local dolphin behaviour in calm, protected waters, making it the most consistent way to swim with dolphins near Perth while keeping things ethical.
Best Time to See Dolphins Around Perth
The good news is dolphins live in Perth’s waters year-round, so there’s no single “dolphin season”. That said, some conditions definitely improve your chances.
Best time of day to see Dolphins:
- Early morning is best, especially just after sunrise
- Late afternoon can also be good if the water is calm
- Midday sightings do happen, but they’re less common
Weather and Water Conditions:
- Calm days with little wind make spotting dolphins much easier
- Sheltered areas like rivers, estuaries and bays are more reliable than open coastlines
- Clear, glassy water often means dolphins are feeding or travelling closer to shore
If you’re planning to join a dolphin swim experience, operators factor all of this in, timing departures around conditions and dolphin movement patterns to maximise your chances.
Top Tips for Dolphin Spotting and Swimming
Whether you’re hoping for a lucky sighting from shore or planning a swim experience, a few simple tips can make a big difference.
For spotting dolphins from land:
- Go early or late in the day when the water is calm
- Look for movement, splashes, or birds hovering low over the water
- Be patient and keep scanning. Dolphins often surface briefly then disappear again
- Bring sunglasses to cut glare on the water
For swimming with dolphins:
- Be comfortable in open water and happy floating calmly
- Listen closely to crew instructions and wildlife briefings
- Let dolphins approach you. Never chase or follow them
Manage expectations. Encounters are always on the dolphins’ terms
General wildlife etiquette:
- Never feed dolphins or try to touch them
- Keep noise and sudden movements to a minimum
- Respect marine park rules and exclusion zones
A bit of patience and the right mindset go a long way. Whether you see dolphins from the shore or in the water, the best experiences are always the ones where the animals get to be wild.
Last Words on Dolphins in Perth
Seeing dolphins in Perth never really gets old. Whether it’s a surprise sighting in the Swan River, a wander along the foreshore in Mandurah, or a calm day down Rockingham way, those moments stick with you long after they’re over.
If you’re happy to take your chances, spotting dolphins from shore can be incredibly rewarding, especially if you time it right and keep your expectations realistic. But if swimming with dolphins is something you’ve always wanted to do, a regulated, dolphin-led experience is the safest and most responsible way to go about it.
