Round four of the 2022/2023 Aeroflow 400 Thunder season, scheduled for Heathcote Park Raceway in rural Victoria on February 11-12, has been canceled.
.
According to 400 Thunder General Manager Jason Hedges, "We have completed our assessment of the overall venue, and the improvements in racer and spectator amenities that had been planned have been de-railed by the massive amounts of rainfall in the local area over the past several months". 

This is the third of the six Pro category events on the 400 Thunder calendar to have been canceled.
  
The next event for the 400T series is scheduled for Willowbank Raceway on April 14-15. 

‘Aussies’ looking for an earlier nitro fix will need to travel to Willowbank Raceway for the Top Fuel Australia New Year Nitro meeting on January 6-7.
