The new categories represented the "innovation life cycle" organisers said.
Another new aspect was the enhanced Fieldays Innovation Hub, where entries would be on display and tested on potential customers, industry professionals and investors.
In the Hub, Fieldays visitors would be able to experience the stages of innovation represented by the three award categories.
As well as two $10,000 cash prizes on offer, winners will receive prize packages from Fieldays Innovations sponsors Amazon Web Services (AWS) and Gait International.
Hendricks said she was looking forward to the awards this year, as the benchmark was set "higher and higher" each year.
"We can't wait to see what's in store for 2021."
Entries for the 2021 Fieldays Innovation Awards close May 1, 2021.
