More rules, more problems. Keep it simple. If I were a trainer in Australia I would go find another job. The only thing that makes people safe is people. When it comes to forklift safety, its about 98%"want to" and 2% "how to". This 400sq m thing and assessing out away from prying eyes is weakening the weak. It's called bureaucracy. I will bet the person who signed off on bill has never even been in a warehouse.

All the best
