Saxon Coral Gardens, which Divers Den calls Coral Garden or Fishbowl, is a gradually sloping coral bank on Saxon Reef that transitions to a flat, shallow, sandy bottom with patches of garden eels. Cuttlefish and turtles frequent the reef edge, larger rays pass through, and the Fishbowl, a sheltered pocket of reef, is a refuge for juvenile fish. Divers Den adds that pygmy seahorses are sometimes sighted amongst the seagrass at the entrance, a rare find on the Cairns reefs and a reason for macro photographers to slow down.

The coral bank is healthy and colourful, with the mix of branching, plate and massive corals that gives the site its name, and it is thick with damselfish, chromis, anthias, wrasse and parrotfish. Dive the World describes Saxon as a series of connected coral gardens and sandy channels, with a shallow bommie dense with staghorn coral, open sand patches, and a gentle slope where sea fans stretch towards the light, and lists turtles, wobbegongs, fusiliers, snapper, Maori wrasse, nudibranchs, hermit crabs, gobies and stingrays among its residents. The gentle profile and modest depth make this an ideal site for new divers, refreshers and snorkellers, while the chance of pygmy seahorses and the variety of small life keep experienced divers busy.

At night the sand and seagrass are productive, with hunting cuttlefish, crabs and shrimps. Saxon is less crowded than neighbouring Norman and Hastings, so the site is often quiet. Visibility is typically 12-18 m, a little lower over the sand when a swell is running.

Boat access only. Cairns day boats leave from the Reef Fleet Terminal (1 Spence Street) and the neighbouring Marlin Marina on the city waterfront, with check-in between about 7:00 and 8:00 am; most operators run transfers from city and northern-beaches accommodation, and there is paid parking near the terminal. The run of about 55 km out through Trinity Inlet and across the lagoon to Saxon Reef takes around 75 minutes on a fast catamaran and noticeably longer on slower dive boats or into a south-easterly chop.

Coral Garden/Fishbowl is a Divers Den mooring on Saxon, also listed by Cairns Dive Adventures. Enter from the stern platform.

The prevailing south-east trade winds (typically 15-25 knots from April to September) are what limit Cairns outer-reef diving: above about 25 knots trips may be cancelled, and exposed eastern moorings are used only in light winds. Summer northerlies are gentler but make north-facing moorings choppy. Box jellyfish and Irukandji are present from about November to May (stinger suits on every dive), and the cyclone season runs November to April, when a system in the Coral Sea can close the reef for days.

Visibility drops after heavy rain and strong winds; spring is usually calmest and clearest. Saxon's western lagoons are sheltered; its weather side is dived only in calm conditions. Coral Gardens is on the sheltered side and is dived in most trade-wind conditions.

Descend onto the coral bank and follow it gently down to the sandy floor at 10-15 m, watching for garden eels and rays. Return upslope along the reef edge looking for cuttlefish and turtles, then visit the Fishbowl and check the seagrass at its entrance for pygmy seahorses before the safety stop.
