The start to summer officially begins tomorrow when daylight saving commences.
This does unfortunately mean we lose an hour of sleep, for a couple of extra hours of light.
Clocks will be turned forward one hour on Sunday 7 October from 2.00am in the states of New South Wales, Victoria, the ACT, South Australia and Tasmania.
Most smartphone devices and computers automatically adjust the time without any human intervention, but analogue clocks will need to be manually changed.
Experts are suggesting, we should be going to bed earlier than normal tonight to help adjust to the time.
"Try to get a bit more sleep in that 24-hour period when the clocks change, be mindful of alcohol and not partying too much," Dr Moira Junge from the Sleep Health Foundation told AAP.
Dr Junge is also urging people to get outdoors in the daylight as soon as possible on Sunday.
Daylight savings is still a contentious issue for some states with Queensland, the Northern Territory and Western Australia not taking part.
