Mark Jeffrey Wilson (born August 1980) is an Australian musician, originally from
Geelong. From 2002 to 2012 he was the bass guitarist of the Melbourne-based rock band,
Jet. He was asked to join them by three founding members,
Nic Cester,
Chris Cester and
Cameron Muncey, but initially refused out of loyalty to his then-current group, The CA$inos. Days later he rang up Muncey and the Cesters and agreed to join their group instead.
