Lionfish IV Diving

Rottnest Island Dive Trips

The Lionfish or butterfly cod is a beautiful delicate tropical fish and is the emblem of the Perth Diving Academy. The Academy has owned various charter vessels over the last thirty years, four of which have been called Lionfish. The current vessel, Lionfish IV is no longer owned by PDA (since 2018)  but we are still able to offer dives from this magnificent vessel through Lionfish Charters.

Lionfish IV, a 24m custom built aluminium vessel was designed for dive groups with all of the comforts required for day and evening charters. Lionfish Charters runs day and evening charters from Fremantle. Lionfish IV also caters for Social clubs and functions for up to 100 passengers on their Swan River cruises.


Lionfish IV dive trips are scheduled to run Saturday, Sundays and public holidays. The double dive trip is $170 excluding hire equipment. Lionfish IV departs for Rottnest Island at 8.30am and returns to the jetty at approximately 3.30pm.
Two dives are carried out and lunch is served on the vessel.
Lionfish does not land on the island or stop at the Rottnest Jetty. A second cylinder for the afternoon dive is included in the price as well as lunch, morning and afternoon tea. Bookings are essential and payment in full is required at time of booking.

You can still come on board even if you aren’t a diver. You may even have an opportunity at lunch time to go for a snorkel. The $85 cost includes the day out on Lionfish IV and lunch,  morning and afternoon tea. You can bring your own snorkeling gear and have a swim or rent snorkeling equipment from the boat before you depart.

Hire Equipment

If you require hire equipment you will need to book and pay for it at the same time as your dive booking. As always, PDA offers the best quality hire equipment in excellent working condition. If you require a complete set of hire equipment the rate is $75 per diver. The hire rates can be found below if you require any equipment:

  • Scuba Unit (BCD, Regulator and Cylinder)   $35
  • Buoyancy Compensator Jacket (BCD)      $15
  • Regulator with computer and compass       $20

All hire gear has to be picked up and organised at either our Balcatta or Hillarys facilities and collected the day before your scheduled dive as we do not have any hire equipment at the departing facility. You will be required to pay a $50 deposit which is refunded after the gear is returned. Please ensure this is organised as we only have a certain amount of hire gear available and cannot guarantee the availability of gear for your trip. It is best to call one of our stores to book hire equipment and make the boat booking at the same time for the most accurate information regarding the trip and availability of hire equipment.

Our Dive Trips

Our professional crew will assist you aboard and give you a short briefing before getting underway. Once at the dive site, our Dive master will give you a thorough briefing on the site so you can pick the best route for your dive. We do not provide in water dive guides. We have a maximum dive time of sixty minutes. The skipper chooses the best dive sites based on the available weather conditions, qualifications and experience of the divers on board.

Before divers enter the water a long mermaid line is launched at all dive sites for ease of return and to keep the area clear from other boating traffic. Once the dive is completed Lionfish IV offers hot shower and toilet facilities for personal comfort. It is also comforting to know that if needed, oxygen and a comprehensive first aid kit are also available. Easy water entry/exit is assured via the side doors and the full width dive platform at the rear of the boat.

Rottnest Island is without question the premier diving location adjacent to Perth. No other Australian capital city can boast such a stunning recreational facility right on its doorstep. With more than 200 individual dive sites to choose from Rottnest offers pristine diving conditions regardless of weather.

Once underwater the diver can experience massive limestone caverns and tunnels interspersed with meadows of sea grass, sponges and soft corals. Torches are recommended for the Rottnest dives with plenty of soft corals and critters to be seen in the large limestone caves.

Warm subtropical currents ensure that the marine environment surrounding Rottnest is one of the richest on earth. The island itself is a rich mosaic of history and culture interspersed with varied recreational activities, to ensure an interesting interlude for even the most jaded traveler. The quiet bays and scenic walks offer something for everyone and after the excitement of the morning diving are charming contrasts. Deep, blue water can be found at the West End of Rottnest Island, although diving is not always possible due to conditions.

Cancelation Policy

If the weather conditions are too rough or the boat doesn’t meet the minimum numbers for a trip you will be informed the day prior to departure. Upon booking the staff will advise you on the best day and time suited to the current forecast.  

Being a commercial operator we reserve the right to cancel a charter if it is not commercially viable or if the weather is unsuitable for our vessel, crew or passengers. We normally will make a decision around 4pm the day prior to departure. On occasion, we may cancel the morning of departure if the conditions are borderline. If you wish to cancel, exchange or transfer your trip you must notify us as soon as possible as we WILL NOT refund unless we can refill your reserved place. When we cancel a departure you will be offered the chance to reschedule, store credit or refund of monies paid in full.
