Crawford "Derek" Mollison excelled at football, cricket and athletics while at Melbourne Grammar, and played three seasons for Old Meburnians after leaving school. Recruited by the Demons for 1923 he was a long kicking, strong marking ruckman who played as an amateur.
First selected to play for Victoria against South Australia in 1924 he was voted the best player on his debut and recieved a hat as a prize. At the end of 1925 he initially retired to play golf, but returned to play three games in 1926. He missed the chance to play in the finals and subsequent premiership due to a knee injury suffered in Round 15.
Mollison gave the game away again at the end of 1926, but midway through the next season he returned to training and offered his services to the club if required. He ended up playing seven matches for the year, and another seven in the next before retiring for good at 27 to pursue his business career. His 1928 campaign had a delayed start due to a dislocated ankle suffered in a practice match. It was his final season, playing seven games.
A younger brother trialled with the club in 1935 but didn't play a senior game.
He enlisted in the army in 1939 and served in North Africa, the Middle East and New Guinea before being sent back to Australia at age 42 to train artillery gunners.
Mollison was returning to Australia when he was killed along with 13 others after their plane overshot the runway at Rockhampton Airport and crashed.
In 1999 he was named in the Melbourne Grammar Team of the Century.
