Unless I misread it, the capital raising is to support the ongoing operations of Cobham group which is a much bigger entity than the Australian aviation operations.
They are a very big military support organisation - which is why their main interests live with the para military elements within Australia such as surveillance and rescue. The airline and resource side just happened to be there when they bought into the business all those years ago, and I guess that they make money so why throw away a perfectly profitable business.
