This year marks the 26th year that Western Australians have celebrated Australia Day with Skyworks.

About 300,000 people are expected to line the foreshore of the Swan River and organisers have sourced a line-up of some of Australia's best entertainment for a range of concerts and family activities.

This year's Skyworks display will paint the sky silver using over 20,000 pyrotechnic effects for the 30 minute show.
