Its just an interest group trying to raise awareness I guess. Of course it's not going to be taken seriously on a wider level.
As someone who eats more Bunnings sausages than anyone else in the Kennel (well, i'm pretty confident of that), our snags of mystery meats are safe I think.
Having said that, I did read that an animal shelter recently somewhere did vegan snags at Bunnings. Not sure how they went though. I would imagine there were a few complaints.
I have only once tried a vegan snag, at a Buddhist festival. It was just basically a falaffel in sausage form. Ok as a one off, but I don't see myself converting (to Buddhism or Veganism!).
Also, as someone who works a lot of sausage sizzles as a Rotarian, you of get some "interesting" requests. We once has a gluten free loaf of bread in case someone asked, but when someone did, I neglected to change gloves when reaching for the gluten-free bread, and this woman looked at me as if i was trying to kill her with the traces of gluten on my gloves.... that was good for a laugh afterwards (especially as she never asked if the snags themselves were gluten free) ... those who are gluten intolerant or just watching their carbs will sometimes just ask for a snag in a serviette.
