If you read the latest briefing from the AFAP, the question was asked, is this reduction of establishment?
Answer: YES (from the company)
So, the scenario is this. There are around 23 positions in Adelaide to be filled. IF they are not filled by the current process of advertised vacancies. The company may direct pilots, irrespective of base or fleet and in order of reverse seniority, to take whatever vacancies are remaining. From there of there are still excess numbers at a base, reverse redundancy may apply at the companies discretion.
I doubt redundancy will be needed however compulsory relocation looks likely.
