One driver had a journey to remember when he spotted a car with a coveted number plate in front of him and quickly snapped a picture of it.
It shows the number plate, with the single number '1' on a Mercedes AMG, which is stopped and waiting for a light to turn green.
Hailing from Victoria, the number plate is estimated to be worth between $2 and $2.5 million, while the luxury Mercedes retails for around $200,000.
The last person reported to have owned the number plate was Peter Bartels, the former CEO of Coles and Foster's Group, although it isn't clear if he was driving the silver Mercedes sedan at the time.
