Gillett, 34, was promoted to the highest pool of selected umpires by Professional Game Match Officials Limited (PGMOL) ahead of the current 2021/22 season in June.
He spent nine years in his homeland refereeing in the A-League, Australia’s highest professional men’s football league, before moving to England in 2019 to referee in the EFL.
After having officiated in Ligue 2, Ligue 1 and the league throughout the 2019/20 campaign, the Australian took charge of the semi-final second leg of the league playoffs between Brentford and Bournemouth.
Gillet awarded a penalty and sent off a Bournemouth defender in a thrilling 3-1 win for Brentford – the west London side beating Swansea in the final to end their 74-year absence from the top tier of English football.
