πŸ“‹The Rundown

🌏

The Great Barrier Reef is the largest living structure on Earth β€” visible from space and stretching over 2,300 km along Queensland's coast

🐠

The reef is home to over 1,500 species of fish, 400 types of coral, 4,000 species of mollusk, and 240 species of birds

🏝️

It's actually made up of nearly 3,000 individual reef systems and hundreds of islands, including 600 continental islands

⏳

The reef is older than most human civilizations β€” parts of it are over 20,000 years old

🐒

Six of the world's seven species of marine turtle can be found on the reef

πŸ“

The Great Barrier Reef Marine Park covers 344,400 square km β€” roughly the size of Italy

πŸ›‘οΈSafety

82

Very Safe

out of 100

The reef is generally safe for visitors, but the marine environment requires respect. Marine stingers (box jellyfish) are present November-May. All reputable tour operators provide safety briefings, equipment, and trained crew. Always listen to your dive instructor.

Things to Know

  • β€’Wear a stinger suit (lycra body suit) when swimming November-May β€” tour operators provide them
  • β€’Don't touch the coral β€” it damages the reef and some coral can sting or cut badly
  • β€’Apply reef-safe sunscreen (zinc-based, no oxybenzone) β€” chemical sunscreens damage coral
  • β€’Stay hydrated β€” dehydration and seasickness are the most common issues on reef trips
  • β€’If you feel seasick, stay on deck and focus on the horizon β€” take medication before boarding
  • β€’Crocodiles inhabit rivers and coastal areas β€” never swim in rivers or murky estuaries
