Document 6: Daylight Saving for South East Queensland: Daylight Saving for South East Queensland (DS4SEQ) was a political party in Queensland, Australia. It was a single-issue party, run by volunteers, that advocated the introduction of Daylight Saving into Queensland, or at the very least into South East Queensland under a dual-time zone arrangement - with the remainder of the state to maintain standard time. The party proposed a possible dual time zone, which included the following 15 local and regional government areas: Brisbane, Fraser Coast, Gold Coast, Goondiwindi, Gympie, Ipswich, Lockyer, Logan, Moreton Bay, Redland, Scenic Rim, Somerset, Southern Downs, Sunshine Coast, and Toowoomba.
