Jimmy Gunawan could become the first person in the world to walk out of an Apple store with the new iPhone 5S.
With only a bottle of water for sustenance, the 33-year-old freelance computer animator is first in the queue outside Apple's flagship store in Sydney's CBD.
Given global time differences, Apple says Australia's east coast stores will be the first in the world to open their doors when the new iPhone 5S and 5C models officially go on sale on Friday.
The George St outlet, one of several Apple stores in eastern Australia, will open at about 8am (AEST).
Mr Gunawan told AAP he plans to buy two of the 5S handsets in the new gold colour - one for himself and one for his mum, who lives in his native Indonesia.

He says he was surprised to be first in line when he arrived about midday on Thursday.
"Last year, I got here around the same time and there was already a queue of about 20 people."
He's planning to stay awake through the night so nobody steals his spot. Apple have given him a chair to sit on.
In case the temperature drops, he has a warm hoodie. He didn't bring any food but is hoping for replenishments from some visiting friends.
He says he wasn't an Apple fan until 2010, when he was converted by the iPad. Since then, he's bought nearly everything Apple has released.
As for his first call with the new phone?
"My mum, probably - to say I got the gold iPhone for her."
