Facts & figures

The largest living
thing on Earth.

Not a metaphor — a single structure, built by animals, visible from orbit. Here is the scale of it, and where our corner fits in.

2,300km End to end, Torres Strait to just off Bundaberg — two thirds of Queensland's coastline
2,900 Separate coral reefs, plus around 1,050 islands from tiny cays to continental giants
344,400km² Marine park area — larger than Italy, and bigger than the UK, Switzerland and Holland combined
1.5cm A year — the growth rate of the hard coral that builds the whole thing. Patience on a geological scale

The life in it

411 hard corals

Plus around 150 species of soft coral and sea pens. The hard corals are the architects; everything else moves in afterwards.

Plankton to 100 tonnes

The reef's World Heritage listing rests on that range — microscopic plankton at one end, whales heavier than a loaded road train at the other.

6 of 7 turtle species

Of the world's seven marine turtle species, six use this reef. Four of them use the water around Lady Musgrave Island.

10% of the world's reef

Roughly a tenth of all coral reef on the planet sits off this one coastline — and it functions as a nursery whose nutrients travel far beyond it.

The statistic that matters to you

80% of the visitors are in 7% of the reef.

Around four fifths of all tourism activity on the Great Barrier Reef happens inside about seven percent of it — the well-trodden stretches off the far north. Two million people a year, heavily concentrated.

The southern end is the other ninety-three percent. Lady Musgrave Island sits in the Bunker Group at the very bottom of the reef, closer to Brisbane than to Cairns, with a fully enclosed coral lagoon and a fraction of the traffic. That is the entire reason we sail from Bundaberg.

And the part that isn't a fun fact

This is a system scientists still don't fully understand, and it is under real pressure — warming water, runoff, plastics, coral bleaching. Pretending otherwise would be dishonest, and it wouldn't help.

What we can do, we do: operate under Advanced Ecotourism and Climate Action certification, run a wind- and solar-powered pontoon, insist on reef-safe sunscreen, hold strict wildlife approach distances, and collect reef health data on trips for researchers who need more eyes on the water than they'll ever have funding for.

Well-run tourism is one of the reef's better allies — it funds monitoring, and it turns visitors into people who care what happens next. Come and see it. Then tell someone about it.
