Sydney Opera House is surrounded by water; the Harbour is kind of like our very own backyard!

Like all backyards - it’s a place that we are responsible for looking after.

But did you know 60% of Sydney’s harbour shoreline has been replaced by seawalls, resulting in small fish and animals losing their homes?

To help restore the natural beauty of our backyard, Sydney Opera House has embarked on a research project led by University of Technology Sydney Professor of Marine Ecology David Booth.

The Reef Project aims to install a modular artificial reef underwater around Bennelong Point, to help bring the fish back and create a new home.

This is just one example of how Sydney Opera House takes care of its surrounding environment. What type of natural environment is near your home? What steps could you take to look after your own backyard?
