Daylight saving

The town of Tweed Heads in the north of New South Wales merges seamlessly into Coolangatta on Queensland's Gold Coast. The two states are ostensibly in the same time zone, but New South Wales observes daylight saving, and Queensland doesn't. That means the twin towns have managed to carve out a peculiar niche as somewhere you can celebrate New Year's Eve twice. Start in Tweed Heads, then stroll over into Coolangatta, and the party starts again an hour later.
