We know now that the member for Griffith’s defence for not building the Wolffdene Dam is that the parliamentary Liberal Party in Queensland at the time was not in favour of it either. So we have had ‘echonomics’; now we have got ‘echohydrology’—we do not have any ideas of our own. But the fact remains that it is not just a question of not building a dam. Views will differ about a dam, about a recycling plant—they will differ about lots of things.
