Behind him, Todd Hazelwood (94), Macauley Jones (81), Garry Jacobson (66), Jack Smith (40), Bryce Fullwood (36), Jake Kostecki (18) and Zane Goddard (15) are drivers with winless starts recorded in double figures.
The new Erebus drivers for 2021, Will Brown and Brodie Kostecki, combine for just 16 championship race starts.
