What the debate has been about as far as the families are concerned is that the laws look too weak - that the protections they want aren't there.

There is debate around what sort of industries should be covered.
Agriculture is one, but what is agriculture? Is it a single bloke in a small farm milking a few cows? Yes. Is that a dangerous profession? Could be I suppose, depending on how you conduct yourself. What about a huge milk processing factory? The devil you see is in the detail.
There are those that are obvious, forestry for example has an abysmal record.
And they stuck number around industries, those with death rates of more than 25 per hundred thousand and injury rates of more than 25 per thousand - that seems sensible.

Health and safety officers funded by employers can't be endlessly wandering corridors and paddocks with high-vis vests and clipboards looking for people doing dangerous things.
