The for and against are fairly far apart for all teams, so if my calculations are correct, to make the final eight:

• Raiders: win v Sharks OR Cowboys lose
• Rabbitohs: win v Roosters OR Cowboys lose
• Cowboys: win v Panthers AND Raiders or Rabbitohs lose
• Roosters: win v Rabbitohs AND Raiders or Cowboys lose

Could be wild as Panthers and Sharks might be resting players
