Betrayer (1984-1994, 2008-present) is a Thrash Metal band from Melbourne, Victoria, Australia.
his band was formed by Ashley Robertson (bass), Dale Robertson (drums) and Shane Ponsford (vocals) with Geoff Marquis (guitars) joining in 1990. The group failed to release anything and shut the operation down to join Virgin Soldiers (sans-Ponsford) before restarting the project in 2008. Chris Farley (guitars) joined on during this second incarnation in 2008 too. So far, they have released only Grandma back in 1993.
