The big news this time of the year, there have been fantastic Minke Whale sightings at all the usual spots. The Minke’s tend to come back to the same reef sites year after year. See the video below from this years season. If you are interested inquire now for next year Minke Whale Expeditions.

The visibility underwater has been great with some guests experiencing 20 to 25 meters underwater. See the photos below from passengers who just returned from the Ribbon Reef dive expedition.

There where even sightings of a beautiful large Octopus scurrying across the top of the reef. These can be very hard to find. But if you are in the right spot at the right time they provide a perfect photo opportunity.

We also reviewed Spirit of Freedoms Osprey Reef Dive Expedition in March. This trip saw 28 divers fly to Lizard Island to meet the beautiful Spirit of Freedom Boat. These expeditions are for Advanced PADI Scuba divers or higher. Osprey Reef is home to large coral sea walls that extend to over 1000 meters deep. The beautiful clear water from the Coral Sea allows for some magnificent underwater photography.
