The vast majority of halal slaughter in Australia (including at export abattoirs) complies with standard slaughter practice where all animals are stunned prior to slaughter. The only difference with halal slaughter is that a reversible stunning method is used, while conventional humane slaughter may use an irreversible stunning method.
The time to regain consciousness following a reversible stun may vary depending on the intensity of the stun. At Australian abattoirs, the aim is to ensure that reversible stunning is done in a way that the depth of unconsciousness is sufficient to allow for the animal to bleed out and die before there is a chance of regaining consciousness.

When may the rest of the world catch up with
humane practices.
And yes the last comment was tongue in cheek because if we eat animals they must die. Amazed by peoples disregard to seafood killing methods, don't they feel pain?
