The Oz Mystery Readers group on Yahoo seems to be fairly active, with some 400 or so messages being posted to the board each month. The group aims to "share opinions and information about crime/mystery fiction available in Australia in paperback." They do welcome members from all over the globe.
They are currently discussing Crook as Rookwood by Chris Nyst, which shared the Ned Kelly Award in 2006 with Peter Temple's The Broken Shore.
