Reef Questions..

What is the difference between the reef sites Silversonic and Silverswift visit?
The reef systems that Silversonic and Silverswift visit are approximately 100 km apart giving rise to very different styles of reef formations and marine life. Both provide spectacular experiences for divers and snorkellers.

Silversonic, from Port Douglas, takes you to the Agincourt ribbon reef systems at the very outer edge of the Great Barrier Reef. Parallel to the Continental Shelf, they are recognized as the most pristine eco-systems in the reef's environment. Clear water provides the best possible underwater visibility, encourages rich coral growth and supports spectacular marine life. Agincourt's formations offer large wall dives as well as great bommie and pinnacle sites.

Silverswift, from Cairns, takes you to many exclusive dive sites on some of the very best Outer Great Barrier Reef locations at Flynn, Pellowe, Milln and/or Thetford Reefs. These sites are chosen for th eir magnificent coral formations, varied marine life and underwater visibility. They have superb ba y-like dive and snorkel sites providing spectacular underwater sand dunes and remote steppingstone- like coral bommie systems. These sites are also renowned for their congregating schools of large pe lagic fish.

Are there any sharks on the reef?
Yes, there are sharks in every ocean and a variety inhabit the Great Barrier Reef. The most frequentl y seen sharks are white and black tip reef sharks which are quite timid and pose no threat to divers and snorkellers.

What is the "Outer Edge"?
The Outer Edge is the where the Continental Shelf ends and deep ocean begins. At the Outer Edge the ocean floor drops from 30 – 40 metres to hundreds of metres. Ribbon reefs are situated on the edge hence the name the "Outer Edge".

Do you really go to the Outer Edge?
Yes, Silversonic travels to Agincourt reef which is a ribbon reef on the very edge of the Great Bar rier Reef. Silverswift travels to Milln, Flynn Thetford or Pellowe reefs, which are considered Oute r Barrier Reefs. They sit approximately 5 km in from the edge of the Continental Shelf.

How many hours are we at the Reef?
You will have over 5 hours at the reef sites combined.

What sort of marine life will we see?
All of our reef sites offer great ecological diversity and an abundance of marine life. Some of the commonly seen marine life include turtles, anemone fish (Nemo), lionfish, cuttlefish, moray eels an d reef sharks.

Will we see whales?
During the months of May to September, there is an added bonus of potential whale sightings as these gentle giants migrate to warm tropical waters to mate and give birth. The commonly sighted species a re dwarf minke and humpback whales. A unique treat is to see the famous Migaloo, a rare white humpba ck whale. Silversonic has one of the few permits available from the Great Barrier Reef Marine Park A uthority that allows our guests to swim with dwarf minke whales if encountered. In season, these inq uisitive creatures are frequently sighted at the Agincourt Ribbon Reefs where Silversonic visits. Th is activity is conducted under strict codes of practice.

Are there any stingers?
At certain times of the year (generally November – April), jellyfish, commonly called marine stinger s, can affect the seas of Northern Australia. Most jellyfish are harmless to man, however certain va rieties may cause a serious reaction. Incidents involving serious marine stings in this area are ext remely rare. Our crew are conscious of the danger of marine stingers and will take appropriate step s to ensure your protection if they believe conditions are such that there is a possibility of enco untering these creatures. Lycra suits are available for hire onboard to reduce the possibility of st ings and irritations while also offering protection from the sun.

Are you just a dive vessel?

What type of dives do you offer?

How deep can you dive?
Our dives are approximately 12 to 18 metres in depth. The Great Barrier Reef is generally not a deep dive destination, more shallow diving. As coral relies on sunlight for growth, some of the best snork elling and diving can be done in shallow areas around the reef top.
