Can't believe they're still yet to get planning permission!
I work in a relevant sector and queried that early on. If that video is recent, then that's still potentially a major hurdle for them.
No doubt the use required an approval that differs from the existing/historical use. They will need to address a range of environmental, traffic, bushfire etc. matters to the satisfaction of the Council/State and likely some vocal locals. If it is refused, only approved in part or, depending upon the circumstances, subject to a court appeal then it will take time and $ to resolve.
Really risky promoting the project like they did if they do not have the planning approvals in place. Great way to piss off the Council, State and locals.
Hopefully it is just an old video and they are way past that now.
