Australia is famous for its coral reefs and aquatic wildlife, but the full moons of March and April signal the arrival of a huge number of animals to Ningaloo reef.
Divers and swimmers head to the 300 km "underwater playground" all year, but this time of year sees the release of thousands of tiny eggs into the warm water.
These eggs represent a wholesome meal for the huge numbers of krill making their way to Ningaloo, which in turn attracts the world’s largest fish, whale sharks.
If you have been dreaming of finding a property in Australia, then the prospect of being able to see a natural event such as this may be all the incentive you need.
A whale shark can be more than 12 metres in length and weigh more than 11 tonnes, but they are also plankton feeders, which makes them safe to dive with.
