Kings Chair is a shallow coral site mentioned by two sources. Bounty Divers, the island's former dive operator, wrote that it has 'coral that seems to be even more pristine than most of the other dive sites' and was known for exceptional conditions. The Marine Life Network lists Kings Chair among Norfolk's shore dives as a shallow site with dense coral.

Norfolk Island's reefs are described by the Marine Life Network as '97% pristine', with plate corals, soft corals, sponges, ascidians, sea stars, brittle stars, nudibranchs, cowries and black coral trees, and Kings Chair appears to be one of the best examples of the shallow coral communities. At 29 degrees south, Norfolk's coral reefs are at the southern edge of coral growth in the Pacific, and dense coral cover in shallow water here is notable.

The name presumably refers to a rock formation resembling a chair, a common source of names on Norfolk's volcanic coast.

Shallow coral sites are ideal for snorkellers and newer divers, but they are also fragile, and fins and hands should be kept well clear of the reef. As with all Norfolk sites, the exposure to the prevailing south-east trades or to northerly swell will depend on which coast it is on. The data confidence is low and depth fields are left blank rather than guessed.

Norfolk Island is about 1,450 km east of Brisbane; flights run from Sydney and Brisbane (about 2.5 h; check the current carrier). A hire car is essential. Norfolk has no harbour: Norfolk Island Diving's open boat is lowered by crane from Kingston Pier (south coast) or Cascade Pier (north-east coast), whichever is in the lee of the day's wind, and divers board from the pier steps once it is in the water.

The site's position is not published; Norfolk Island Diving chooses Kingston or Cascade Pier according to the wind, and most sites are 5–20 minutes from the pier.

Norfolk sits in the south-east trade wind belt. South-easterlies (strongest May–September) make the south coast and Kingston launch rough, and dives move to the north coast from Cascade; northerlies (more common in summer) do the reverse. Any swell over about 1.5–2 m on the exposed side stops the crane launch.

Visibility is typically 20–40 m. There is no stinger season; ex-tropical lows occasionally bring big seas in summer–autumn. Where this site sits relative to those exposures is not published – ask the operator.

Follow the guide over the shallow coral, keeping buoyancy well off the reef to protect it.
