Plenty! Currently the most important single thing you can do is respond to the City of Joondalup’s “public consultation”. According to the City, if you attend an information session and want to add more to your submission, you can fill out the online consultation form again and your responses will be aggregated.
MBCG has organised a petition you can sign to pressure the council into rejecting the draft plan.
You can contact your local councillor directly to express your concerns (keep in mind they cannot speak against decisions made by council), and direct any questions to firstname.lastname@example.org.
Also importantly, you can stay up to date by following MBCG on Facebook, signing up to our mailing list, and joining the Stop The Groynes group on Facebook (please note: this Facebook group is not associated with MBCG Inc).
