We’re local divers, we’ve lived in Port Douglas for many years so we can tell you a lot of what you need to know about Port Douglas diving. Scuba diving from Port Douglas is good, it’s always a fun day out and you can visit some diverse and beautiful dive sites. This post particularly reviews a recent day out diving from Port Douglas with Divers Den on their Aqua Quest day boat, but we also give you lots more information on Port Douglas Diving.

A fleet of boats leaves Port Douglas almost every morning bound for the Great Barrier Reef, many clients will be snorkellers, others will be divers. Some won’t want to swim at all, they will enjoy the reef from mini subs and glass bottomed boats. We already have a full post on Great Barrier Reef tours from Port Douglas, this post deals exclusively with scuba diving from Port Douglas.

Port Douglas Diving

Port Douglas Diving Port Douglas Superyachy Marina. The dive fleet departs Port Douglas from the marina every day

Early morning at the Superyachy Marina in Port Douglas. Your day diving on the Great Barrier Reef starts here. It’s not a bad start to the day!

Most of the dive boats heading out from Port Douglas will be carrying snorkellers as well as scuba divers. There are specialist dive only boats,  but as one of our party isn’t yet scuba certified, we stick to the combined boats. To us there are no disadvantages, the diving is good. Dedicated snorkel boats also operate out of Port Douglas.

As well as the standard Great Barrier Reef dive sites reachable from Port Douglas, there are some pretty special places and scuba experiences nearby. We’ll mention those too.

What’s the Best Time of Year to Dive From Port Douglas Australia ?

It depends on what you want to see. If you’re looking for whales then you will want to come in our winter. Whale season in Australia is long, roughly May to November but obviously our coast is also long and best time of year varies with location. The humpback whales and dwarf minke whales arrive in our waters off Port Douglas around June – July and will hang around until roughly September. Of course their exact schedules vary. It is possible to swim with the minke whales on some dive boats. I’m very pleased to be able to tell you that my husband is about to do just that and we’ll be covering it on the website and our social channels.

Water Temperature for Scuba Diving off Port Douglas

Water temperature off Port Douglas, on the great barrier reef fluctuates between roughly  22º C and a maximum of 30º C. If it gets to 30º C we’re in danger of coral bleaching so nobody wants that.  June , July and August are our winter and you’ll see water temperatures in the low 20s. In December , January and February the water is pushing towards that top 30º. This is our summer and the tropical wet season.

Wet Season Diving – Summer in Port Douglas

Wet season coincides with Stinger Season. The marine stingers can hang around until April or May. Your chances of encountering a dangerous jellyfish on the reef are lower than from the shore but everyone wears stinger suits out there in season.

The wet season is low season in Port Douglas, so you may be lucky and catch special offers and reduced prices for dive packages. The special offers can continue into April and May. By June things are getting busy.

Wind and Visibility Variations

Visibility and wind are a little more unpredictable but generally speaking, it’s possible to have a great diving experience from Port Douglas at any time of year. Bad weather and low customer volume does sometimes stop the boats running, but rarely. We’ve never not seen a stunning selection of marine life on the reef but we have dived in some choppy conditions.

Port Douglas Diving – What Will You See?

 The Great Barrier Reef is home to over 1,500 fish species, 411 types of hard coral, one-third of the world’s soft corals, 134 species of sharks and rays, six species of marine turtles plus more than 30 species of marine mammals. It’s busy out there!

The above creatures are mostly present year round. As already mentioned the dwarf minke and humpback whales are seasonal visitors. Other seasonal events worth timing your trip for are coral spawning and turtle breeding season.  Coral spawning can be in October,  November or December depending on location. (source)

When diving from Port Douglas some of the stand-out creatures are sharks, turtles, maori wrasse, jellyfish, cleaner shrimp, crabs, barracuda, and parrot fish. You will see some amazing corals, maybe stag coral, brain coral, mushroom coral and soft corals.  

Special Minke Whale Diving Trips

If you’re looking for a minke whale expedition, you need to be here in June or July and you must book, places are limited. Find more information here. As I said, my husband is about to try one of these minke trips and we’ll be covering it here.

Which are the Best Dive Sites From Port Douglas?

It’s hard to quantify best because best is just a matter of opinion. We very much enjoy just about any of the outer reef sites.

Port Douglas is closer to the ribbon reefs than Cairns and most of our local boats take divers north to Agincourt Reef.  The trip takes about an hour and a half. There’s some great easy diving along walls, around bommies and in coral gardens

There are a few stand out dives locally, the Cod Hole and Castle Rock dive sites are well-known, for these you’ll have to find a specialist operator.

Scuba Diving From Port Douglas with Divers Den

Port Douglas Diving on Aqua Quest by Divers Den

Off we go for another day diving from Port Douglas. Today on AquaQuest, one of DiversDen’s fleet. Yes, those are our children. The elder one scuba dives, he passed his Open Water certification at Divers Den’s dive school in Cairns, our younger son snorkels. Mum and Dad are both advanced PADI divers and have been scuba diving over 20 years, all around the world.

Divers Den is a company we use often, we’ve dived with them from Port Douglas and Cairns on their day boats as well as spent 4 days with them on a liveaboard out of Cairns. My son learned to dive with Divers Den, at their Cairns based dive school and qualified on their day boat out of Cairns. I, as an anxious scuba mum, was impressed with how that went.

 Our day with Divers Den started at 8 am, unlike other Port Douglas dive operators we didn’t need to check in at an office and could check in on the boat which better for us, less hanging around.

After checking in and being  kitted out with dive gear we enjoyed coffee and cake until cast-off time. No hot drinks may be served while the boat, AquaQuest, is in motion. The boat was over half empty for us, this makes for a great day on the reef, less rush, more space on the dive deck and less humans in the water. I’d say that generally you’d expect less crowded boats out of Port Douglas than out of Cairns, but obviously, it’s seasonal.

AquaQuest is new, spacious and modern. I’ve not been on a better reef boat out of Port Douglas or Cairns. The moorings she uses vary on the day, dependent on weather. She uses Agincourt, Opal and St Crispin’s reefs. Our day was spent on Agincourt Reef.

The dive briefing was held while the boat was cruising towards the reef, which was great, no wasted dive time once we arrived.

The dive gear we were given was good. We generally don’t take our own dive gear to the reef other than special masks. Sometimes I take my own wetsuit, I’m not a standard size and my own suit fits me better.

 The First Dive Site

 We geared up about 10 minutes before arrival at the first dive site on Agincourt Reef. This first site was pretty good in my opinion. We swam for almost 40 min before getting back on the boat to refill the tanks, grab a coffee and chill for a short while and then we were back in the water for a second dive, this time heading in the opposite direction for a different dive experience.

Lunch on the Reef

After the second dive comes lunch, buffet style. Hot food was very welcome on a slightly cooler day in late May. We haven’t seen hot food on any of the other dive boats recently. Vegetarian and gluten-free options were available and everything was tasty and abundant. When lunch is done Aqua Quest moves to her second mooring of the day. This may only take 5 – 10 minutes.

The Second Dive Site 

We were straight in the water for the third dive of the day. This dive also gave us around 40 minutes exploring a wall.

Introductory Scuba Dives

An interesting feature on AquaQuest, introductory scuba dives take non qualified divers on a trip of discovery. Each dive instructor takes a small group on one introductory dive. Novices hold onto the instructors arms, using full scuba gear, as he steers them through the reef.

The instructor takes full responsibility for monitoring air, depth and all the tech, the new divers just have to look and fin gently. I can’t begin to imagine how mind-blowing this must be for people who’ve never dived before. These instructors are good, they taught my son, we know them from the liveaboard, I think you’d be in very safe hands.

Guided Dives or Buddy Dives on Divers Den Aqua Quest 

We loved that guided dives come included in the price on Aqua Quest. On some other boats a guided dive can cost $15 per person. For our family, that adds up fast. My husband likes to buddy dive, my son and I enjoy guided dives. We always see more on a guided dive and by some voodoo our air lasts longer. Our intrepid buddy diver also has a tendency to surface, maybe not quite where he intended.

After 3 great dives it’s time to go home.  Be sure to have something warm and dry to change into for the return trip. More coffee, fruit and cake inside us, we all fell asleep in the comfort of Aqua Quests main saloon. The bar is open, of course, but we were out cold without alcoholic refreshment.
