to a victory over Kolkata Knight Riders, before going on to play in four further matches before Delhi were eliminated at the end of the group stage. Despite playing in only five matches in the tournament, Billings again saw the experience as one which would help him "improve as a player". In particular, he cited the influence of Delhi's coach Rahul Dravid and had approached the IPL, which he rated as a "phenomenal experience", with the intention of developing his skills, particularly against spin bowling. He has credited the experience of working with players from around the world as a major factor in the improvement of his game, from the use of different training methods to eating more effectively. Billings was retained by Delhi for the 2017 Indian Premier League with the intention of him playing until 1 May in order to return to England to play against Ireland and prepare for the 2017 ICC Champions Trophy. In November 2016 Billings signed to play for Sydney Sixers in the 2016–17 Big Bash League in Australia. He made his debut for the Sixers in the opening match of the tournament, taking two catches as the team beat Sydney Thunder by nine wickets. After appearing in the Sixers first five matches of the tournament, Billings left the team to join the England squad in India at the beginning of January 2017. He batted four times for Sydney, averaging 31.25 runs. After playing again for Sydney in the Big Bash League in 2017/18, Billings was bought by the Chennai Super Kings in the 2018 IPL auction for £71,000. Although he scored a match-winning 56 runs in Chennai's second match of the tournament, a rather disappointing tournament saw him score 108 runs at an average of 13.60 in 10 matches and he did not play in the final as Chennai won the title. In 2018 he captained Bengal Tigers in the T10 League played in the United Arab Emirates having been picked second in the competition's draft in July. A break from overseas T20 leagues saw him play more frequently for Kent, before he was signed to play for Sydney Thunder in the 2020/21 Big Bash. In February 2021, he was bought again by Delhi ahead of the 2021 Indian Premier League, missing the start of Kent's season, although he did not play a match for the side during the competition.
