Criteria for the perfect beach:
Hot and humid weather
Powdery sand
Absence of debris/pollution on the sand and in the water (including rocks)
Access to world-class accommodation, food & supplies nearby
Clean, clear water that smells great
Soft gradient into the water - no sudden drops into the “deep end”
Choice of crowds and surf just by going up and down the coastline
Queensland beaches have it all. The best I’ve experienced anywhere in the world so far.
