Following the retirement of club veteran Royce Simmons at the end of the 1991 season, new recruit Brett Boyd was selected in the starting hooker position over Alexander to begin 1992.
[5] An injury crisis at the club (including to Boyd) allowed Alexander to remain in the starting line-up (playing at either halfback or hooker) until the week prior to his death.
[5] At approximately 10:10 pm on 21 June 1992, Alexander, aged 20, was killed in a car crash in Colyton, a suburb in Western Sydney.
The crash occurred shortly after Alexander left the function with teammates Scott Murray, Luke Goodwin, and Glen Liddiard to attend a nightclub in Mount Druitt.
[6] Although early reports claimed that Alexander had not been drinking that evening,[6] it was later confirmed by the coroner that his blood alcohol content was 0.148, which is almost three times the legal limit of 0.05.
[13][11] Greg Alexander, Liddiard, and Brook Kennedy were granted leave for an impromptu trip to Greece in July, which Geyer also attended.
[14] Greg Alexander, who had been sidelined with a knee injury since April of that year,[15][16] returned to the field on 2 August, playing off the interchange bench against the Manly Warringah Sea Eagles.
