2008
As a junior, Kokkinakis had a breakthrough when in March 2008 he won the 12 year old National Lawn Tennis tournament in Mildura beating Joshua Bray 6–1, 6–2 in the final.
This was a big stepping stone after being beaten in the previous 12 year old National Hardcourt Tennis Tournament in January 2008 by Lochlan Greene in straight sets in the round of 16.
This tournament was won by Nick Kyrgios.
2009
In 2009, Kokkinakis was selected with fellow Australian tennis representatives James Ma, Li Tu and Daniel Talens, on a Tennis Australian European tour.
He has repeatedly said that this tour changed the course of his career.
2011
Kokkinakis began his professional career in March 2011 at the Australia F3 Future's event at the age of 14 where he lost 6–8 in the third set tiebreak to Leon Frost.
He recorded his first professional win the following week against Kento Takeuchi at the Australia F4 event.
He then lost in the second round to Michael Venus.
2012
In 2012, after playing Futures events in Australia, Slovenia, Germany and the Netherlands, Kokkinakis equaled his best result of the year by reaching the semifinals of the Belgium F4 event.
He then returned to play Futures in Australia where he reached back to back quarterfinals in the F5 and F6 events, losing to Luke Saville both times.
He finished the year by reaching the semifinals at the Australia F12 event where he lost to Ben Mitchell.
2013
He won one junior Grand Slam title, the doubles title at the 2013 Wimbledon Championships with partner Nick Kyrgios, and was the runner-up in two additional junior Grand Slam singles finals that same year.
Kokkinakis received a wildcard into the 2013 Australian Open juniors tournament and eventually reached the final taking down the 12th, 2nd and 11th seeds on his way.
In the final he faced fellow Australian Nick Kyrgios.
After having two set points in the first set he eventually lost 7–6(7–4), 6–3.
In June, he returned to competitive play at Wimbledon, and made the third round in the boys' singles and won the boys' doubles with Nick Kyrgios.
Kokkinakis lost the final of US Open Boys' Singles, losing in three sets against Borna Ćorić, 6–3, 3–6, 1–6.
Following the result, Kokkinakis reached a career high junior ranking of 10.
He began 2013 by filling-in on the United States and German teams during the 2013 Hopman Cup as a replacement for injured John Isner and Tommy Haas.
Kokkinakis competed in the qualifying competition of the 2013 Australian Open, losing to Steve Johnson 15–17 in the third set.
Kokkinakis sustained a stress fracture in his back in the Australian Open boys' final which kept him out of competition until mid 2013.
He then returned to competition playing Futures tournaments in the Czech Republic, Canada and the United States with the highlight being a quarterfinal of the Canada F5 event.
In September and October, Kokkinakis competed in two Challenger events in the United States.
2014
Despite still being eligible, Kokkinakis elected not to play junior events in 2014 and instead focused on the men's tour.
2015
He has won one ATP Tour title in singles and produced his best Major singles performance by reaching the third rounds at the 2015 and 2023 French Open.
Kokkinakis also has a career-high doubles ranking of world No. 15 attained on 21 November 2022 after winning the 2022 Australian Open and reaching the semifinals of the 2022 Miami Open with countryman Nick Kyrgios.
As a junior, Kokkinakis was ranked as high as No. 10 in the world.
As a professional, Kokkinakis broke into the top 100 for the first time in 2015, during which he won one title on the ATP Challenger Tour and made the fourth round of an ATP Masters 1000 tournament for the first time at the 2015 Indian Wells Masters.
2016
After an injury-plagued 2016, he reached his first two ATP Tour finals the next year, when he won the 2017 Brisbane International doubles title with Jordan Thompson but lost at the 2017 Los Cabos Open in singles to Sam Querrey.
2018
In 2018, Kokkinakis won two additional Challenger titles and ended the year having re-entered the top 150.
However, over the next two years, further injuries prevented him from regularly competing on the professional circuit, but he made his return in 2021 and he reached two Challenger finals, of which he won one.
He continued his comeback in 2022 and appeared in his first ATP Tour final in five years at the 2022 Adelaide International 2, in which he prevailed in front of a home-town audience to secure his maiden ATP Tour singles title.
He then won the Australian Open doubles title partnering Kyrgios, and the pair competed in the year-end championships.
