Horse meat is not even meat?

Just had my attention drawn to a tweet from a student of nutrition...

@triplejHack According to Food Standards (see pg.6)http://j.mp/9vAJtT - horse is not even considered "meat" by definition in Australia!

So what standards are they using to ensure the horse meat being served in WA is safe for human consumption? Food safety policy is not something you can make up as you go along...
