Daylight saving ends at 3am tomorrow, Sunday 7 April, so it's time to turn back clocks, watches and timers by one hour.

Mornings will be lighter and evenings darker as South Australians regain the hour they lost last October.

Queensland, Western Australia and the Northern Territory do not observe daylight saving and so the time difference between them and other states and territories will change.

The clocks will go forward again by an hour in South Australia, Tasmania, Victoria, New South Wales and the ACT on Sunday 6 October.

As daylight savings comes to an end, the South Australian Metropolitan Fire Service and Country Fire Service are urging all South Australians to change their smoke alarm batteries, when winding their clocks back.

Throughout 2023, nearly half of all significant house fires in South Australia occurred in homes with either disabled smoke alarms, flat batteries, or no smoke alarms installed at all.

Earlier this year, a St Agnes home caught fire overnight, and the presence of working smoke alarms saved two lives and prevented approximately $400,000 of damage to the property.

Most fire-related deaths are caused by the inhalation of smoke and toxic fire gases rather than from direct contact with flames or heat.

Correctly located smoke alarms in your home give early warning of fire, providing the precious time which may be vital to survival.

Both fire services recommend the best protection is provided by interconnected photo-electric smoke alarms which are hard-wired to the 240-volt power supply to give the earliest warning possible.

Jeff Swann, MFS Chief Officer, says only working smoke alarms save lives.

"If there’s a fire in your house, every second counts when you and your family are trying to escape. The more you prepare, the better your chances are of survival.

"On average, we lose 64 Australians every year in preventable house fires, and around 2,000 Australians suffer from serious burns. By checking you have a working smoke alarm, you give yourself the earliest possible warning to evacuate safely."
