No, to the contrary; there are blue holes in the Great Barrier Reef (GBR).The GBR is a 2700km long complex with over 2900 individual reefs. A few of these reefs have blue holes in them.

More recently the roof of some of these rivers and tunnels would have collapsed leading to the formation of these "blue holes". I personally know of only one, but there are surely a few.
