Weedy seadragons, grey nurse sharks, and shore diving in the middle of a city
Twenty minutes from the center of a city of five million people, there are shore entries where you can see weedy seadragons: animals that don't exist anywhere else in the world.
In this guide you'll find out why the temperate water off this coast has the wildlife it does, where and when to see seadragons and grey nurse sharks, how shore diving works here, what wetsuit you need, and what skill level is required.
It's the most accessible proof that temperate diving has endemic wildlife the tropics can't offer, and that you can dive well without leaving a major city.
Geography and access
Sydney sits on Australia's east coast, where a warm current flowing down from the north meets temperate waters from the south.
That meeting produces an unusual mix: tropical species passing through in summer alongside resident temperate wildlife, and some endemic species.
The coastline alternates sandstone cliffs, sheltered bays, and rocky reefs covered in sponges, kelp, and sea squirts. There's no reef-building coral, and that completely changes what the seabed looks like.
The common seadragon, a relative of seahorses with leaf-shaped appendages, is a resident of these rocky reefs and doesn't exist outside Australian waters.
In certain months, grey nurse shark aggregations gather in the region's caves and rocky ledges. It's an imposing-looking animal with calm behavior, and it's threatened.
Access couldn't be better: an international airport right in the city, and shore dive sites just minutes away by public transport or car.
