Cavarra is from Lysterfield, a suburb of Melbourne, and was educated at St Joseph's in nearby Ferntree Gully. He spent a successful stint of junior football at the Eastern Ranges in the TAC Cup, starting by winning the 2012 Pennington Medal as a bottom-age player. A strong 2013 season followed; Cavarra captained the Ranges to a premiership, winning the TAC Medal as best on ground in the grand final. He also tied for the Morrish Medal on 16 votes, and won a second consecutive Pennington Medal, a feat that had previously been matched only by Sam Mitchell and Rory Sloane. Cavarra also represented Vic Metro at that year's AFL Under 18 Championships. He missed out on attending the national draft combine, instead attending the Victorian session, where he ran a 20-metre sprint in under three seconds, a personal best. Cavarra was not selected in the 2013 AFL draft, despite his accolades; clubs were chiefly concerned about his short stature, but also his lack of speed and kicking accuracy. He considered joining a VFL team, and decided on the Frankston Dolphins, as the club was not affiliated with an AFL team, meaning he would have a greater chance of playing in their senior side. Cavarra had largely played as a midfielder prior to joining Frankston, but expressed a desire to take on a forward-line role. Over three years at the club, he played 51 games and kicked 44 goals, and won Frankston's best and fairest in 2014 and 2015, earning interest from West Australian Football League clubs. Despite Cavarra's strong performances, he continued to be overlooked in AFL drafts. Frankston, in financial difficulties, decided not to compete in the 2017 VFL season. Cavarra joined another VFL team, Williamstown, where he switched to a small forward position. He kicked 66 goals in 40 matches over two seasons; in both, he led the club's goalkicking and was named in the VFL's team of the year.
AFL career
Cavarra was selected by the Western Bulldogs with pick 45 in the 2018 national draft, marking his first successful nomination after five failures. His first season was marred by injury; he could only play 12 VFL games after suffering hamstring and quad tears, fractured ribs, which caused a minor cut to his liver, and a broken scapula. Over his off-season he practised Pilates sessions to strengthen his body, ensuring he could complete pre-season training. He made his senior debut in the opening round of the 2020 season, scoring a goal with his first kick.
Personal life
Cavarra studied a teaching degree at Wesley College, working part-time as a teaching assistant during his course. After his AFL debut, he cited education as a career to potentially return to after finishing with football.
