I have found some references to a Mangalore Airspace Study.
- CASA advised on 3 Sep 2021 that they were conducting such a study <https://consultation.casa.gov.au/stakeholder-engagement-group/mangalore-aeronautical-study/consult_view/>, consultation for which ended on 30 Sep 2021 <https://www.avsef.gov.au/all-consultations?title=Mangaloreso>
- I would have assumed it would be published by now, but there is nothing on the CASA website.
