DOB: 16 August 1964
From: Port Adelaide, Selection #37, 1987 National Draft
From a long line of accomplished footballers, with his father and grandfather both players in the South Australian league, Obst began his career in the South Australian amateur competition and represented the Australian Amateurs at the 1988 Bicentennial Carnival.
Drafted in 1987 he didn't travel to Victoria until 1990, but was a quality contributor in the midfield once he got there. Lucky to avoid lengthy injury, Obst was troubled by minor complaints throughout his career. Nevertheless he played 22 of 24 games in his first year and never less than 15 for a season. His 1991 campaign was delayed by a broken collarbone suffered in a practice match, not returning to the side until Round 11.
In 1996, Obst finished third in the Best and Fairest, but after an ordinary 1997 season it became clear that it would be Obst's last year, and he was stranded on 149 career games after being suspended for two weeks for striking Peter Sumich in Round 20, 1997. He retired from AFL football after the 1997 season, returning to Port Adelaide in the SANFL and winning another premiership in 1999 before giving up the game for good.
In 1990 Obst was sued by ex-South Adelaide player Brenton Honor who made a $100,000 claim regarding an alleged strike in a reserves match the year before.
