Reef Trips in Cairns: Six Hours on the Water

Key takeaways

Check in forty-five minutes before departure, cross for seventy-five minutes each way, and spend six hours at the reef split by a sit-down lunch.
Both stops sit at Upolu Reef: the Wonder Wall, where the coral comes close to the surface, and the Aquarium, with Upolu Cay nearby.
Pastries and fruit on boarding, tea and coffee all day, a smorgasbord lunch with prawns and smoked salmon, and cake on the way back.
A port and administration fee is paid at check-in, separate from the booking, along with certified or introductory diving if you choose either.

Getting to the boat, and off the dock

Check-in for this trip, run by Ocean Free and Ocean Freedom, is at the Ocean Freedom desk at the Reef Fleet Terminal in Cairns, and it needs to happen at least forty-five minutes before the boat leaves. From the terminal it is a three-minute walk to the catamaran itself, a twenty metre vessel described as fast, which is the boat for the whole day.

Once everyone is aboard, the crossing out to the reef takes seventy-five minutes. Danish pastries and fresh fruit are served as the boat gets moving, with tea and coffee available on boarding and again through the day whenever the boat is moored. There is no stop on the way out: the seventy-five minutes covers the distance to Upolu Reef, on the outer edge of the Great Barrier Reef, where the day's two sites are.

Six hours split across two named sites

The reef time itself runs to six hours, spent at two places, both on the outer edge of Upolu Reef. The first is called the Wonder Wall, where the coral comes to within about a metre of the surface. The second is known as the Aquarium. Upolu Cay, a coral cay built up from sand and coral fragments on the reef, sits nearby too.

The published order is two and a half hours at the reef, an hour for lunch, then another two and a half hours at the reef before the boat turns for home. That is five hours at the two sites either side of a sit-down lunch, which is a long way from a quick look over the side and back to the mainland. Both sessions cover the same two named sites, so there is no need to choose between the Wonder Wall and the Aquarium: the day includes both, twice.

What the guided time in the water involves

A marine naturalist runs the snorkelling, set up as a guided drift snorkel: the group moves with the current along the reef rather than swimming back and forth against it, with the guide leading the way. There is also a glass bottom boat tour, for anyone who would rather watch the reef from above the surface, and getting into it means being steady enough to move between the main vessel and the smaller boat and back.

All the gear needed is provided, including prescription masks for anyone who needs one, flotation devices, and lycra suits, with wetsuits available seasonally. The lycra doubles as a stinger suit, which matters because marine stingers, including box jellyfish and Irukandji, are a genuine seasonal hazard in tropical Queensland waters, broadly across the wetter half of the year. Fish feeding is part of the day too, and fresh water showers are on board for afterwards.

What is on the table, and when

Food on this trip is not an afterthought. Boarding comes with Danish pastries and fresh fruit, and tea and coffee are available from boarding through the rest of the day, wherever the boat is moored. Lunch, taken during the hour between the two reef sessions, is a full smorgasbord: prawns, smoked salmon, a mixed meat and chicken platter, three salads, and bread, with chilled water alongside it.

On the way back, the food changes again to platters of tropical fruit, cheese, crackers, and assorted cakes. Between boarding snacks, a full lunch, and an afternoon spread, eating is built into the rhythm of the day rather than squeezed in around it.

The return crossing, and what is not included

The crossing back to Cairns takes the same seventy-five minutes as the trip out, arriving back at Ports North roughly eight and a half hours after check-in began. A port and administration fee is payable at check-in and is not part of the booking made in advance. Certified and introductory diving are also separate, if either is something you want to add.

Alcoholic and soft drinks, underwater cameras, hotel pickup and drop-off, and any snacks bought on board are not part of what is included either. Chilled water is provided throughout, and everything listed in the food above is covered, so the extras are genuinely extras rather than gaps in the basics. The included food alone runs to three separate rounds across the day, from the pastries at the start to the fruit and cake platter near the end.

Who the day suits, and what to bring

This is not a trip for anyone with mobility impairments or who uses a wheelchair. Getting around a moving vessel, and transferring between the main boat and the glass bottom boat and back, both take a degree of steadiness. Anyone considering the diving options needs to be free of a medical issue or medication that would rule diving out on the day. A medical form is filled in at the terminal, and a diving doctor's clearance may be needed for anyone with a relevant history. In Queensland, the minimum age for an introductory dive is twelve.

Pack sunglasses, swimwear, a towel, sunscreen, and something to change into afterwards. Everything for the water itself, snorkelling gear, suits, and flotation devices, is provided on board, so the day is really about being ready for sun and spray rather than for the reef gear itself. The operator also holds an Ecotourism Green Travel Leader listing.

Check dates

Before you book

How long is the whole day?

The day runs eight and a half hours in total: forty-five minutes to check in, seventy-five minutes out, six hours at the reef, and seventy-five minutes back to Cairns.

How long is spent at the reef itself?

Six hours, split into two and a half hours before lunch and two and a half hours after it, all at sites on Upolu Reef, on the outer edge of the Great Barrier Reef.

How long is the crossing each way?

Seventy-five minutes each way by catamaran between Cairns and Upolu Reef, so an hour and a half of the eight and a half hours is spent travelling.

What happens at each reef site?

There is a guided drift snorkel with a marine naturalist at both the Wonder Wall and the Aquarium, plus a glass bottom boat tour for anyone who prefers to stay dry.

When is lunch served?

Lunch is the hour between the two reef sessions: a smorgasbord of prawns, smoked salmon, a mixed meat and chicken platter, three salads and bread.

What food is included on this trip?

Danish pastries and fruit on boarding, tea and coffee all day, a full lunch smorgasbord, and fruit, cheese, crackers and cake on the way back.

Is the day rushed?

No. Five hours at the two reef sites either side of a sit-down lunch, out of eight and a half hours total, keeps the pace unhurried rather than tight.

Is a port fee included in the booking?

No. A port and administration fee is paid separately at check-in and is not part of the booking made in advance.
