Discovering the Rottnest Island Boat Dive Day Trip — A Practical Guide

Imagine spending a full day exploring underwater gems just off the coast of Perth. This 8-hour boat trip from Fremantle takes you to the colorful reefs, limestone caves, and marine playgrounds of Rottnest Island, one of Western Australia’s most celebrated diving spots. For around $174 per person, you’ll enjoy two boat dives or snorkel adventures, a delicious catered lunch, and plenty of time to soak up the stunning scenery from the water.
What we particularly love about this trip is how close the best dive sites are to Perth—meaning less time traveling and more time enjoying the underwater spectacle. The spacious 68ft twin-deck catamaran makes for a comfortable and stable platform, perfect for relaxing between dives or just admiring the views. Plus, the crew’s reputation for safety, friendliness, and local knowledge really shines through, making the experience welcoming for both seasoned divers and those new to snorkeling.
One aspect worth considering is that this trip doesn’t include a landing on Rottnest Island as part of the main package—although you can choose to be dropped off for an extra fee. If you’re hoping for a full island day, you’ll need to plan for that separately. Lastly, since the group size is limited to 40, it keeps the atmosphere intimate and manageable, ideal for those wanting a more personal experience.
This tour is perfect for divers and snorkelers eager to explore WA’s marine marvels, families looking for a fun day on the water, or anyone wanting to enjoy a well-organized adventure without the hassle of island logistics. If you’re comfortable with moderate physical activity and love the idea of spending a day surrounded by stunning ocean scenery, this trip will suit you well.

A Detailed Look at the Experience

Starting the Day — Fremantle Departure
Your adventure begins early at the Fremantle Fishing Boat Harbour around 8:00 am. The meeting point at Molfetta Quays is easy to find, especially if you’re staying in Perth or Fremantle, with public transportation nearby. The boat, a spacious 68ft twin-deck catamaran, provides a stable, comfortable environment to begin your journey. We loved how the large deck offers plenty of space to relax, chat with fellow travelers, or simply enjoy the water views as you cruise toward Rottnest.
The Marine Environment — What You’ll See
Once anchored at Rottnest’s prime diving sites, the two scheduled boat dives unlock the treasures of colorful coral reefs, limestone caves, and swim-thrus—all formed by the island’s porous limestone geological makeup. The soft rock’s unique structure has created deep crevices and secret underwater passages, as one reviewer happily pointed out, “crav[ing] the caves and swim-thrus like I’ve never seen before.”
Water clarity and marine life are key highlights. Expect to see an abundance of fish, perhaps a giant ray (as one diver described), and marine treasures that make the effort of the trip worth every penny. The crew’s professionalism shines, notably during challenging weather conditions, with reviewers praising how they handled weather and gear setup with expertise and calm.
Diving and Snorkeling — For Every Skill Level
The two dives are a major highlight, especially since one air cylinder is supplied, making it easier for divers to focus on exploring rather than logistics. If you want to do a second dive, you’ll need to bring or hire a second cylinder. Snorkelers also get special tender rides, giving access to the best shallow reefs and underwater caves. The gear included is clean and in good shape, and the crew is attentive to gear setup, which reassures especially those newer to underwater adventures.
Lunch and Refreshments — A Delicious Break
After the morning’s adventures, you’ll enjoy a catered buffet lunch, with vegetarian and vegan options available if specified 24 hours in advance. Many reviews mention the impressive quality of the food, with some calling it the “best lunch” they’ve had on a tour. Throughout the day, endless tea, coffee, biscuits, and lollies keep everyone fueled and happy, complementing the relaxed, friendly vibe onboard.
The Return — Views and Reflection
As the day winds down, you’ll cruise back to Fremantle around 3:30 pm. The water views from the boat are fantastic, providing plenty of opportunities for photos and peaceful reflection on the day’s highlights. For those interested in dropping off on Rottnest Island, fees apply, but this allows extra time to explore or relax ashore—something many travelers find appealing.
The Value of This Tour

At $173.85, this experience offers substantial value. You receive two boat dives or snorkel adventures, a full meal, snacks, and marine park fees, all on a comfortably sized vessel. Compared to organizing similar activities independently, the convenience and safety of a guided trip are well worth the cost.
The reviews consistently show that professional and friendly staff elevate the experience. Many travelers appreciated how staff members like Ethan, Alana, and Dario created a safe, fun environment, which is especially important when venturing into unfamiliar waters.
Who Will Love This Tour?
This trip suits adventurous families, groups of friends, or solo travelers who want a hassle-free day on the water. It’s especially good for divers of all skill levels, as the crew is attentive and safety-focused. If you’re a snorkeler, you’ll appreciate the tender rides to prime snorkeling spots, while divers will love the proximity to some of the best underwater features near Perth.
