The DA for twisted is still there as Regional Council hasn't discharged it. The only part of the agreement that would require amendment is the commencement of construction.
But an initial report from staff would be required to consider MPS amendments to do Skye. Let's face it; it doesn't meet any rules and that doesn't have to be approved by council. They could shrug it off and vote to not initiate the process and if they did, there would be no appeal.
Here is an example of a typical initiation report and as you can see by the alternatives on page 4 the only two options are to proceed or not to proceed. So a complete application is still required - but the process doesn't start until the report is given thumbs up or down by council. But this is only for an application that would require an MPS amendment.
