As he foreshadowed before the WACA Test against New Zealand, Mitchell Johnson has had enough, and will retire immediately from international and first-class cricket at the end of the match.

In the lead-up to the match, Johnson said he was happy to keep playing "as long as I'm performing well and doing my job in the team then mentally I'm feeling pretty good", but this week, Johnson has been conclusively tamed by Kane Williamson and Ross Taylor, returning the figures of 1 for 157, the most expensive by an Australian bowler in all Tests in Perth.

His manager Sam Halvorsen was in the Australian dressing rooms on the fourth evening, as Johnson reached the painful decision to end his Test playing days.

"I feel now is the best time to say goodbye," Johnson said. "I have been lucky enough to have had a wonderful career and enjoyed every moment of playing for my country. It's been an incredible ride.

"But the ride has to come to an end at some point and to do so here at the WACA is very special. I've given the decision a lot of thought. Beyond this match, I'm just not sure that I can continue competing consistently at the level required to wear the baggy green.

"My career has certainly had its up and downs but I can honestly say I have given it my all and am proud of everything I have achieved. To win an Ashes series and a Cricket World Cup is something I will treasure forever.

"My family have been by my side throughout and I could not have achieved all I have without their support. They have made a lot of sacrifices, especially my beautiful wife Jess who has provided me with unconditional support, and I am incredibly grateful for that.

"They say the greatest thing about playing sport is the friends you make along the way and I have been fortunate enough to play and work with some incredible people and have cemented lifelong friendships.

"I would certainly like to thank the people of Australia, and all those around the world, who have supported me. The encouragement I have received has been extremely humbling and playing in front of them is certainly something I will miss."

Johnson has played 73 Tests, claiming 311 wickets for Australia, behind only Shane Warne, Glenn McGrath and Dennis Lillee. He was the key figure in Australia's 5-0 Ashes sweep in 2013-14, claiming a staggering 37 wickets across the five Tests and leaving an indelible mark with his pace and intimidation.

A follow-up performance in South Africa further enhanced Johnson's reputation as one of the most frightening fast bowlers to have played the game, but his returns have trailed off gradually since, and after struggling for impact in the two Tests of this series against New Zealand he has decided to finish - doing so before the inaugural day/night Test in Adelaide, a concept he has been notably sceptical about.

His state coach Justin Langer paid tribute to Johnson's achievements. "Mitch's career has been a wonderful example of what is required to endure the rigours of a life of professional cricket," he said. "He was injury-ravaged early, written off, criticized and probably wondered whether he would ever make it.

"This in mind, it is a testament to his courage, resilience, and skill that he retires as one of Australia's greatest ever fast bowlers. As an athlete, he is peerless and few could bowl as fast.

"Above all that, it would be hard to meet a nicer bloke. Inside the tough exterior is an outstanding young man, who has been a credit to his family and the Australian cricket family."

Johnson's retirement rounds out a sequence of six exits from the national team around this year's unsuccessful defence of the Ashes in England. Ryan Harris, Michael Clarke, Chris Rogers, Shane Watson and Brad Haddin all left the stage before the home summer, and Johnson had admitted to thinking about joining them, only committing fully to playing a few weeks before the season began.

His decision has also coincided with the maturing of Mitchell Starc, who has developed consistency to go with his pace and swing and has notably outdone his more senior left-arm paceman at the WACA Ground. The dual use of Starc and Johnson in the same attack has been a source of considerable selection angst for several years, no more so than against England when they struggled for role definition as two strike bowlers in a four-man attack.
