What is the name of the famous reef of the north coast of Australia?

off the east coast of oz

I also believe it is the only part of the earth that is visible from outer space

Gintaras, north east

Player #29684811, I was there 12 years ago and I could see the coral was all bleached, too many tourists and I read somewhere suncream can also affect it

I always thought Queensland was in the East of Australia.
