Jess, 26 Oct 23
Had a great day out on Silversonic from Port Douglas. Visited 3 snorkel / dive spots. The dives were fun! Saw a few reef sharks, lots of Nemo's, Giant clams and other interesting marine life. morning tea, lunch and afternoon tea were all included and they had nice veggie options. The boat it small, but not over crowded which was good. I'd travel with them again!
India Rose Long, 22 Oct 23
My favourite day so far up the east coast! Me and my 3 friends went on Silver Sonic because we had heard it’s the best reef in Cairns and we definitely weren’t disappointed! From the moment we got on the boat to the moment we got off, it was just incredible! I did 3 dives, the equipment was already organised and was in perfect condition and the instructors and crew were so kind and knowledgeable! The boat itself is immaculate and the food was delicious! The reef was pristine, lots of beautiful coral, colourful fish and reef sharks! I have done many dive boats in Australia / South East Asia and this one was definitely up there with one of the best! Thank you to the Crew on SilverSonic and to Taylor from Cairns-Tours / The Travel Shop for booking us onto the most perfect trip!
Tamara Robbins, 16 Aug 22
SUCH A GREAT DAY!! I cannot believe how much there was at the reef! SO MANY FISH! Trevally and a HUGE barracuda! Even a couple of turtles and a little whitetip shark!
Adam Harvey, 26 Jul 22
I've been out diving a few times off Cairns and this is the best boat I've done in FNQ, well worth the drive up to Port Douglas
