Dick
For all your intelligence and experience, you appear to have become an unusually slow learner.
To get what you want, you only need 3 people on your side, but none of the three reads pprune.
Their surnames are Windsor, Katter and Oakeshott. Get them onside, and Julia will give you anything you want. Once she's seen the 'strength' of your argument, Julia will move Willytown, if that tickles your fancy.
There's no point arguing with the monkeys, Dick (especially when the monkeys can shoot your arguments down so easily). (Speaking of bad arguments, if orbitting in a single engine aircraft off Nobbys is so dangerous, V1 must be closed, now. And how many people died at Lockhart River, and what changed as a consequence?)
You need to convince the organ grinders, Dick. And the organ grinders are interested in only one thing: getting and staying in power. The merits of your arguments are relevant only to the extent that they impact on the organ grinders' interests. Bad news for you: Without Windsor, Katter and Oakeshot up your sleeve, your arguments about Willytown have zero impact on the organ grinders' interests.
