He came to worldwide attention as a prominent member of the Australian squad that won the 2015 Cricket World Cup, and was declared Player of the Tournament as a result of his consistent performances throughout the matches.

Starc and fellow fast bowler Clint McKay took nine wickets between them in Sri Lanka's innings to set up an eight-wicket win for Australia.

However, upon his arrival in the United Kingdom, Starc was detained and questioned at Heathrow Airport for more than four hours then deported because his visa forms had not been filled out correctly.

[52][53][54] Before the start of the 2012/13 summer in Australia, Starc played in the 2012 Champions League Twenty20 for the Sydney Sixers, alongside fellow national team fast bowlers Pat Cummins and Josh Hazlewood.

[62] Upon his return to Australia, Starc admitted that he had lost seven kilograms due to a gastric complaint during the World Twenty20 in Sri Lanka and a follow-up illness during the Champions League in South Africa.

Due to the intense schedule for the Australian team in the upcoming year, Starc chose to forgo surgery to fix the issue which would have taken him out of the side for up to three months.

India had won the series at the end of the 3rd Test match, so rather than risk Starc's ankle spur becoming a bigger problem, the team's management sent him back to Australia for surgery with the hope that he would be recovered in time for the tour of England.

Australia needed one more wicket to win the match, but New Zealand's final batsman, Trent Boult, was able to defend the last two balls of Starc's spell.

Starc's form made him a big threat to England, with former Test cricketer Graham Swann describing him as "beyond the best match-winning player they've got at the minute.

He and wicket-keeper Peter Nevill put on a partnership of 64 runs to keep Australia in the game, and Starc scored 58 before he got out, but this wasn't enough to prevent England from winning the Test match within 3 days.

[134] Starc took a wicket in the opening over of the match, reminiscent of the 2015 World Cup final, as Australia bowled out England for a mere 138 runs.

[135] During the match, Starc bowled a ball which struck England captain Eoin Morgan on the side of his helmet and forced him to retire hurt due to concussion.

[157] In the final Test match, Starc took his third five-wicket haul in three innings, but struggled with deep footholes on the pitch at SSC Cricket Ground.

[164] Former teammate Mitchell Johnson tipped him to continue breaking records through the 2016/17 season,[165] but during a practice session he had an accidental collision with training equipment and suffered a deep shin laceration.

Indian commentator Aakash Chopra said that this display showed why he was considered the "best fast bowler in the world", because "he bowled every ball with a single-point agenda of picking wickets".

[182] Starc was deemed fit to play in the Champions Trophy, giving Australia a full-strength lineup with Josh Hazlewood, Pat Cummins and James Pattinson all available as well.

[187][188] After the tournament, follow-up scans were taken of Starc's foot and showed that his stress fracture had not fully recovered, so he was ruled out of Australia's tour of Bangladesh in August and September.

[189] Starc returned from this injury to play in the first two rounds of the 2017–18 Sheffield Shield season for New South Wales as a way to prepare for the 2017–18 Ashes series.

[198] Starc was considered fit enough to play in the final match and the following ODI series, but his bowling was much slower than usual and he didn't pose as much of a threat to England's batsmen.

[199][200] Starc spent time recovering from his injury before traveling for Australia's 2018 away tour of South Africa, where he had not previously played red-ball cricket.

[204] In the second Test match, Starc came into disagreement with his captain Steve Smith over how to bowl to South African batsman AB de Villiers.

I am my own best coach and I know what's best for me.Scans after the match revealed that Starc had torn his left pectoral muscle, so he was declared unavailable for Australia's tour of India in February and March 2019.

[229][230] He was seen as a very important part of Australia's chances at the World Cup because of his performance in 2015, but his lack of recent match practice but into doubt how well he'd bowl this time.

[233] West Indies captain Carlos Brathwaite thought that the umpiring mistake was highly consequential in the match result, saying, "To lose Chris in a chase of 280, who can probably get 180 of them himself obviously, broke the start that we wanted to have.

[240][241] Although, he just played a solitary game in the Ashes, taking 4 wickets across two innings, as Australia chose to rotate their fast bowlers over the course of the series.

[citation needed] On 16 July 2020, Starc was named in a 26-man preliminary squad of players to begin training ahead of a possible tour to England following the COVID-19 pandemic.

He performed throughout the series, with both the ball and bat, scoring runs as a capable lower-order batsman and picked up 19 wickets in 5 matches with a bowling average of 25.36.

ESPNcricinfo editor Nagraj Gollapudi opined that both players were let off leniently, as the punishment in the code of conduct could have been up to 100% of their match fee as well as a two-match ban.

[262] He missed the IPL in 2016 because of a foot fracture injury and in February 2017 parted ways with Royal Challengers Bangalore in order to reduce his workload and focus on his fitness for the upcoming 2017 ICC Champions Trophy.

He was ruled out of the 2018 Indian Premier League due to injury, having tibial bone stress in his right leg sustained in a Test series against South Africa.
