Preparations for the huge picnic started before sunrise. The famous bridge in Australia was transformed into a grassy picnic area to celebrate a food festival.
Around 6,000 people got together for the outdoor breakfast!
The bridge, which is usually packed with cars taking people to work, was closed to traffic for the event.
All eight lanes were covered in grass so people could sit comfortably.
These people look very happy tucking into their snacks! Picnickers brought bags full of fruit and croissants - and organisers handed out freshly baked bread, jams and yoghurt.
They were chosen from 45,000 people who applied to take part in the event.
These cows also put in an appearance!
After the event the grass was rolled up again - ready for morning traffic.
