The strong southerly and the exposed nature of the Motorplex course meant it was strength in numbers for the riders.
The juniors faced only a single lap, with Madisson McAulisse continuing her form from last week to take the win.
Gabriel Glorie was second after his sister Kassandra made a mistake on the approach to the final corner, but she recovered to finish third.
In E grade William Lendrum was putting in an audition for D grade, chasing the D stragglers to take the win comfortably. Anita Watters chased hard for second and Ashton Sime was third.
In D grade, Oliver Bleddyn took the win in a sprint finish, with Richard Ramos second and Emma Lendrum third.
C grade had only five riders take to the circuit.
While there were numerous attempts to drop riders, the five stayed together and in the sprint it was Kelana Saleh first, Ron Mcarthur second and Darren Lee third.
In B grade the bunch had been reduced to half of its original size when Mark Glorie attacked on the bell for the final lap. Nicola Nizzi quickly joined him while the rest of the riders tried to chase the two down.
But Nizzi was too strong and rode away to win with Jordan Dawson, the best of the chasers, finishing second. Glorie held on for third.
In A grade, Conor Leahy, Ryan Willmot and Matthew Peterson broke away early, leaving the pursuing 17 riders in disarray.
With five minutes to go, Leahy just rode away from his breakaway companions to take the solo win, with Willmot pipping Peterson for second.
Next week, the racing returns to Smeaton Way, Rockingham, for the final criterium race of the year.
