"I should never have played the Davis Cup final," Tsonga told Europe 1 radio, ahead of Mondays Grand Slam.
In the Davis Cup final against Switzerland, Tsonga, who had been struggling with injury, played against Stan Wawrinka but lost in four sets and then withdrew from the rest of the match which the Swiss won 3-1.
"Knowing all that, obviously I should never have played the final, like I should never have played Bercy (November), like I should have not played at all from the month of September to have time to recover from this injury and be fighting fit for the 2015 season," he said.
Tsonga said that he loved playing for his country, despite "sacrificing practically nine weeks a year (for Davis Cup) at the expense of (my) personal career."
"You mustn't get everything mixed up," said Tsonga.
"Playing for the France team is a duty for me. On the other hand playing professional tennis is my job. I knew straight away that it was 'dead' for Australia, that I had 'killed' any chance I had of recovering quickly. Professionally it was very important for me to go there (Australian Open)," he added.
Tsonga is expected to be out of action for six weeks to recover from his injury.
