Y - Australia The prefix Y is reserved for Australia. For many (but not all) Australian ICAO codes, the second letter indicates which flight information region (FIR) the airport belongs to – B Brisbane, S Sydney, M Melbourne and P Perth. However, the Sydney and Perth FIRs no longer exist and have been merged into the Brisbane and Melbourne FIRs, although the airport codes remain unchanged (e.g. Sydney YSSY, Darwin YPDN).
