I may have given the impression that our whole coastline and beaches are all rock. Not so. I tend to take photos of rocks because I think they make a more interesting photo than endless stretches of clear, sandy beaches.
However, here are a few photos, taken on several visits, to beaches at Tomikan, Mossy Point, Broulee, North and South Head at Moruya, Tuross, Narooma and Mystery Bay. All of the beaches, covering a 50klm stretch of the NSW south coast, are typical* of most beaches around 30,000klm** coastline of Australia.
*Tanya has just commented that these beaches are in fact atypical of beaches in northern Australia where the waves have to cross the reefs. (See her comment.)
** This is an approximate coastal measurement. Different methods of measuring produce different results, also depending on whether islands, esturaries, etc. are measured too.
