love showing people.

And, I mean, yes, we have instruments that will ensure that we have better quality and higher throughput and that we don't have people doing something that a machine can do better.

But the machines need looking after and...

A person needs to be there at the beginning and at the end in order to make sure that the right things have happened because otherwise the wrong things happen.

And there are so many examples where systematic errors have occurred on a grand scale and they've been avoidable.

And the quality controls, quality assurance systems that we have in our laboratories in Australia are incredible.

Or you're keeping in touch of what's happening globally? What do you do practically to do that? Because I think that doesn't always come naturally to people.
