Mako Island, Mako Mermaids Wiki

Mako Island is a real island in the two popular television series' H2O: Just Add Water and Mako Mermaids. It's located approximately 50 km off the Gold Coast. Mako Island was formed by a comet that crashed into the Earth. One of the shards impacted near Ireland (Eire) forming the Sea Caves of Ireland. Other shards would have landed in other locations creating moon pools wherever they impacted. Mako Island has been around long before humans walked the earth and it will still be around long after
