Souths thumped the Roosters last night and face losing grand finalists Manly in round two in Gosford next Friday.
The Rabbitohs put their defeat by the Roosters in last year's final-round, minor-premiership showdown behind them with the 28-8 win at ANZ Stadium, but the scars from their preliminary final loss to the Sea Eagles run much deeper.
Souths have an early season chance to atone for that heartbreaking defeat.
"Playing last season's grand finalists in the first two rounds is a good way to work out how we are doing no doubt about it," Inglis said.
"We couldn't think of a better way to start the season, as a team and as a club.
"You can only see how how we are playing in where we go from here, next week it starts again with Manly up in Gosford.
"But in saying that we have to sit back and enjoy the weekend and get ready for Monday."
Inglis spearheaded the Rabbitohs' win with a hat-trick of tries and paid tribute to new halves of Adam Reynolds and Dylan Walker in helping to pave the way.
"I think they give us a great edge especially with 'Sutto' (John Sutton) in the middle, another big forward playing five-eighth," Inglis said.
"So it frees them up and Dylan Walker with his feet out the back there gave us a bit of room."
The Rabbitohs enjoyed an impressive pre-season win over St George Illawarra in the Charity Shield but Inglis said he was uncertain entering the season proper uncertain due to a truncated preparation courtesy of the World Cup.
"You never know how you are going to go in these games, you can play all the trials you want but in the end round ones are always an unknown," he said.
"That first 60 minutes was very hard, very brutal but in the end we ran away with it."
