Greyhounds in NSW and the ACT no longer have to wear a muzzle in public when being walked on-leash, provided that they are lifetime-registered on the Companion Animal Register. While a greyhound is in foster care or on trial adoption they will need to wear a muzzle outside of the home at all times. Greyhounds are not allowed unmuzzled in off-leash areas unless they have a GreenHound exemption.
