Observance is a state matter, and only two of five mainland states have chosen to participate. Therefore, continental Australia became five time zones for six months out of the year, a decision that has created a bull-headed debate among all its states. This has an error - three of five mainland states and one territory observe daylight saving time (SA, VIC, NSW and ACT).
