Johnson last season joined the Scorches from the Brisbane Heat, but had not played a Big Bash game until donning the orange and his impact was immediate.
The powerful left-armer ended the season with the fourth-most wickets at 13, with his average of 15.46 among the best of the full-time bowlers, and was the only bowler in the competition to record multiple maiden-overs.
However, it was his outstanding showing against the Melbourne Stars in the do-or-die semi-final that punctuated Johnson’s season, as he recorded the most economical spell in BBL history with figures of 3-3.
His devastating performance included a two-wicket maiden in the first over of the game and it was not until his 18th ball that he conceded a run, creating the platform from which the Scorchers first progressed to the Final, then went on to capture their third Big Bash crown.
“Returning for another season is a pretty easy decision when you’ve got a team like the Perth Scorchers,” Johnson said.
“Not only have they played well over the years, but they’re also a great bunch of blokes.
“If I’m honest and look at what happened last year – winning the BBL title with the Scorchers and then winning the Indian Premier League with the Mumbai Indians – I should probably retire on a high, but Twenty20 is more and more becoming a game that the older guys can play.
“I also feel like there’s some unfinished business.
“I want to help the team go back-to-back and, given this is the last season at the WACA Ground, I really can’t wait to get back out there and enjoy the atmosphere the amazing crowd creates.”
Johnson’s signing takes the Scorchers roster to 15 of 18 spots, with two spaces available for international recruits.
The Scorchers’ opening BBL game is a rematch with last season’s Final opponents the Sydney Sixers at the SCG on 23 December, with the side’s first home game at #TheFurnace against the Melbourne Stars on Boxing Day.
