Technology that allows grapes to be sorted in the paddock is just one of dozens of innovations being showcased at an agriculture exhibition.
The AgSmart event is being held at Bendigo in regional Victoria and aims to display the latest developments across the sector.
"Ag tech in Australia is a burgeoning industry and we wanted to place a spotlight on the latest technology and innovation," Kate Nugent from ACM Rural Events said.
“Adoption of ag tech will ensure the industry can produce, supply, and store food and fibre sustainably."
It's the second time the event has been held with the first staged in NSW last year.
Other exhibits include technology that shows farmers how to optimise their water using artificial intelligence.
Organisers say all of the displays were chosen because they were Australian-made inventions.
"There's been an explosion of ag tech startups that are happening across Australia," Ms Nugent said.
“It will provide insights into the future of Australian farming."
About 2000 people, many of them farmers, are expected to pass through the gates during the event which winds up on Friday.
