Unfortunately numbers alone will not send a message at this meeting. When you attend these you will see that everything is scripted. No one knows if you are there in support or opposition or if you are there because your neighbours cubby house looks over your fence. To be able to talk at this you must pre submit an application which states exactly what you will be talking about, this application is sent to all the councillors and the "technical experts" so that the reply that is given is pre determined (as much as they try to seem like they are answering off the cuff). You can submit a question form at the meeting, though there are restrictions on what the question can refer to and are quite often rejected. (too hard basket)
The only other way to have your say now is to email the CEO of the city, all correspondence to the CEO will be passed on to the relevant person/body, reviewed by them and the CEO, and MUST be responded to. The CEO is the one that will be submitting the management plan to the state for approval, after the councillors decide what options will be included, so bombard him.
And if you think that we can hold it up when it goes to the state then you are wrong as there are no third party appeal rights in Australia.

I have spoken to a representative at the City and was informed that Option 2 was introduced following the consultation period at a stakeholder meeting held by the mayor. Therefore this option was never presented to those who completed the survey and if you had agreed to exclusion zones you have now agree not only to the exclusion zones that were listed in the draft for consultation but also agree to the one added after the fact. Criminal! The Mayor should be hung!
This has all come about from the squeaky wheel at Mullaloo Beach and it looks like it will get some greasing. I say become a squeaky wheel in the ear of the CEO, email away regardless if you can or cannot make the briefing session.
A group of people at an organised briefing is manageable, but a hundred emails a day that must be responded to is a right pain in the arse, probably worth greasing

No expert, just my 2 cents.
