Good Friday is a significant Christian holiday that is observed worldwide, including in Australia, which typically falls on the Friday before Easter Sunday. It commemorates the crucifixion of Jesus Christ and his death at Calvary. For many Christian denominations, Good Friday is a day of fast and penance, which is classified as a day of deep mourning. Numerous church services are held, and some communities reenact the path Jesus took through the streets of Jerusalem on the way to crucifixion.

In Australia, Good Friday is a public holiday, with most businesses closing from Good Friday to Easter Monday. Many Australians attend special church services, while others use the long weekend as an opportunity to go on a short vacation or spend time with family and friends. Particular attention is given to the Easter story in Christian communities, with special prayers and readings from the Bible. People also participate in charity works, focusing on peace and reconciliation.

Moreover, certain traditions and activities are unique to Australia. In the state of Victoria, the Melbourne Cricket Ground hosts a match every year on Good Friday, it's one of the few days when Australian football matches are played. In many Australian cities, there is a tradition of conducting 'hot cross bun' baking competitions on this day. These buns, marked with a cross on the top, are symbolic of the crucifixion, and have now become an integral part of Good Friday celebrations in Australia.
