Pre-season testing will be held across two different dates at separate venues in 2021.
On Friday 12 February, Queensland-based teams, along with Team Sydney, will test at Ipswich's Queensland Raceway.
Victorian-based teams, as well as Albury-based Brad Jones Racing, will hit the track at Winton Motor Raceway on Friday 19 February.
The tests will mark a vital chance for teams and drivers to prepare for the new season.
Neither day will be televised, but official pre-season testing can be followed with Supercars.com's live timing.
