The City of Perth Skyworks (Formerly the Lotterywest Skyworks) is a fireworks show that is held over the section of the Swan River in Perth, Western Australia known as Perth Water. It is held every Australia Day on 26 January. The Skyworks show usually runs for half an hour and has involved fireworks launched from bridges, sky scrapers and moving boats in the past. The fireworks are choreographed to a soundtrack which is played on the radio while the fireworks are underway.
