Meowsy won Australia D1 from pole to claim a first IMS victory for Haas. Rochamoya finished second from fifth and piastrigoat completed the podium from sixth.
The winner held the only unchanged grid position in the top three. Behind, Rochamoya gained three places and piastrigoat gained another three to reach their final slots.
Thirty-two of Haas's 46 points
Haas scored 46 BOTT points from eight starts, with one win, one podium and one top-five finish. Meowsy's 32 points supplied all three countback markers and nearly seven-tenths of the total.
Ferrari led the full round with 144 points and four podiums. Haas's lower total did not dilute the D1 outcome; it showed how isolated the victory was within the team's weekend.
Piastrigoat takes 20 points to Japan
Piastrigoat's third place raised the championship leader to 221 points, 20 ahead of TheMekanic17. Meowsy kept the race win while Ferrari's contender gained the larger title cushion.
Japan followed with Meowsy newly established as an IMS winner. Australia had given Haas a round of modest breadth and perfect concentration: one top-five finish, parked in exactly the right place.
