Why Can’t We Have Daylight Saving in Brisbane, and What Are the Costs?

Ever own a Jawbone fitness tracker? If so you might have been swept up in the (now-defunct) company’s 2014 user survey of sleep and exercise patterns.

 

Using anonymous data collected from hundreds of thousands of people in 29 countries, the company looked at, among other things, user bed and wake-up times. The result? Brisbane was the earliest-rising city in the world, with the average Brisbanite rising at 6.35am. We were also the first to hit the sack, at 10.54pm.

 

But it makes sense. In the middle of summer, Brisbane, squeezed towards the leading edge of its time zone, witnesses sunrise at 4.49am (with light creeping across the sky much earlier again) and sunset at 6.42pm. That compares to Melbourne’s longest day, when the sun rises at 5.54am and sets at 8.42pm; and Sydney, which sees the sun emerge at 5.41am and set at 8.05pm.

 

Of course, Melbourne and Sydney – and Adelaide – have the benefit of daylight saving in summer; it shifts their clocks forward an hour. Which leaves many Queenslanders asking: Why don’t we do the same?

 

Adopting daylight saving “makes sense”, says Dr Thomas Sigler, a senior lecturer in human geography at the University of Queensland.

 

Despite being hundreds of kilometres east of Melbourne, Brisbane slips an hour behind the Victorian capital in summer. “Adelaide is 30 minutes ahead of us right now, and Adelaide is even further west,” Sigler says. “So we’re completely out of sync, geographically.”
