Prodrive Racing Australia have confirmed Cameron Waters rookie test day has been postponed due to wet weather.
The team told Supercars.com the test day is likely to be rescheduled for tomorrow if the weather improves.
Waters was due to test his #6 Monster Energy Falcon at Winton Motor Raceway today for his final rookie test of the year.
Supercars permits a team a maximum of three rookie driver test days for the sole purpose of testing and practice for a rookie driver.
In 2017 the young racer will no longer be classified a rookie, having had a year in the Virgin Australia Supercars Championship under his belt.
