Just from reading the article, it looks like ANZ on downwind, about to be turned onto the ILS. Qf, on the ILS, gets told to turn away from the unidentified conflict and climb to 3000' under the ANZ descending 4000' on the downwind. Qf gets the GPW and climbs to 5000' (company SOP?). Sound reasonable?
Raises a lot of questions. Hierarchy of instructions, authority etc. eg. If the hierarchy is GPW, TCAS, ATC, visual/avoid having a prang, this would be a perfect example of common sense being removed from the equation and the domination of following set procedures to the detriment of safety. ie trying to write checklists for every possible situation.
