Millions of Australians in NSW, Victoria, South Australia, the ACT and Tasmania woke up an hour short of sleep this past weekend, as clocks jumped forward for daylight saving. Queensland, as always, didn’t join them, and the familiar debate over whether it should has reignited once again, this time alongside genuinely compelling new health research that goes well beyond the usual political arguments.

Queensland’s long-running stand-off

Queensland last voted on daylight saving in a 1992 referendum, meaning no Queenslander under the age of 52 has ever had the chance to vote on the issue themselves. Two petitions are currently before Queensland Parliament calling on the government to reconsider its position, backed by growing support from business groups who argue the current arrangement hurts productivity and makes coordinating with interstate colleagues and clients genuinely difficult.

Premier David Crisafulli has been unambiguous in his response, describing another move toward daylight saving as a “hard no.” The Queensland government has also ruled out holding another referendum, despite the renewed pressure.

Associate Professor Thomas Sigler, a human geographer at the University of Queensland who has researched the issue extensively, says the current arrangement genuinely puts the state “out of whack” with the rest of the country, noting Brisbane’s December sunrise can occur as early as 4am, a time when very few people are actually awake to make use of it. He’s also pointed to real, localised friction points, such as residents who commute daily across the border between Tweed Heads and the Gold Coast, crossing time zones as part of their everyday routine. Sigler believes a south-east Queensland-only arrangement could be genuinely workable, noting Australia already has precedent for individual states operating across more than one time zone.

What the debate usually misses

While Queensland’s daylight saving argument has traditionally centred on lifestyle, business and tourism, a new piece of research out of Canada adds a genuinely important health dimension that’s often missing from the conversation entirely, and it applies just as directly here.

Published in the Canadian Medical Association Journal, the analysis makes clear that simply deciding whether or not to observe daylight saving isn’t actually the full question. The more important decision, the researchers argue, is which time a community lives on year-round, because permanent daylight saving and permanent standard time carry genuinely different health trade-offs.

Lead author Dr Raymond Lam, a professor of psychiatry at the University of British Columbia, said the health evidence points toward standard time, largely because morning light plays a critical role in regulating our body clocks, sleep and mood. Co-author Dr Ralph Mistlberger, a professor of psychology at Simon Fraser University, explained that our biological clocks genuinely need morning light to stay properly synchronised with the 24-hour day, and that daylight saving pushes that light later, precisely when mornings are already at their darkest during winter.

The researchers note that permanent daylight saving does carry real benefits too, longer evening light can make it easier to exercise, socialise or run errands after work. But those evening benefits, according to economist Dr Patrick Baylis, need to be weighed against evidence linking later solar time with reduced sleep, lower productivity and worse outcomes in schools.

A genuinely useful lesson from elsewhere

The research also points to a pattern worth Queensland paying attention to: multiple countries that have tried permanent daylight saving have ultimately reversed course. The United States adopted it during the 1974 energy crisis and abandoned it within a year, amid public concern over dark winter mornings and children travelling to school before sunrise. Russia did the same in 2011, reversing it in 2014 after public dissatisfaction, and Chile reversed its own 2015 experiment for similar reasons.

Why this matters for older Queenslanders specifically

While the research didn’t focus specifically on older adults, the broader findings around circadian rhythm disruption are genuinely relevant to anyone managing sleep difficulties, something we’ve covered extensively in our own Six-Week Wellbeing Plan series this year. Disrupted morning light exposure has real, documented links to sleep quality and mood, both of which become increasingly important to manage well as we age.

Where it stands now

For now, Queensland remains firmly on Australian Eastern Standard Time year-round, alongside the Northern Territory and Western Australia, while the rest of the country has now shifted into daylight saving for the summer ahead. Whether the renewed petitions and business pressure amount to anything more than the state’s familiar, decades-long debate remains to be seen, but as this latest research makes clear, there’s considerably more at stake in that decision than simply what time your clock says.
