Comet Bay College is in Secret Harbour, Western Australia. It opened at the start of the 2006 school year at the premises now occupied by Comet Bay Primary School, but moved to its present location south of the primary school in 2007. The college was initially a junior high school accommodating years 8 to 10, but in November 2007 it was announced by the Minister for Education that years 11 and 12 would be accommodated in 2008 and 2009 respectively.
