Australia Day is the 26th January and is a public holiday across the nation.
Most people head for the beach and have a picnic with friends and family. Sydney Harbour has a ferry race and there are fairs at many parks.
In 1788 the first fleet arrived from Britain and it was the day our first Governor, Arthur Philip raised the British flag. From then onwards, convicts and free settlers arrived.
Unfortunately they also bought disease, gunpowder and some not very nice opinions of the local indigenous people, which led to conflict and their numbers decreased. This is why today Aboriginal people refer to it as Invasion Day.
There has been debate about moving Australia Day to another day, but until then, we will continue to celebrate this great day with a BBQ and a swim at the beach.
