I will state up front, I haven't read the Navy article, nor have I the ability to at the moment. But, that summary sounds familiar to a number of the bullshit old white man views in RAAC and RAInf.... and as background, I aided the collation of data considering the integration of women into infantry, so have seen most of this before.
I don't know the details of this report, but there is pretty constant engagement with the AHRC and the military over the past 3 - 4 years. I have participated in two myself. I'm sure there are reasons and deeper levels, but the two I was in were simply asking questions about culture. We weren't steered, nor constrained from replying. I actually found them a breath of fresh air compared to some other culture and investigative 'interviews'.
An advantage to using AHRC is it's independent and there is no risk to subordinates. It allows juniors to speak honestly and frankly (and I'm sorry, but the ADF has becoming increasingly bad at allowing that). It is also an expert in culture. And many of the problems in the ADF today - procurement, budget, workforce - all trace back to culture. Finally, AHRC changes nothing in the ADF, it's an adviser. The SLG gets reports and makes the call.
Every PWO I know (and I worked with 6 - 7 directly over the past two years + know another two dozen) received an invite to chat with the AHRC. At least 3 sneered at it that I know of (and anecdotally from my PWO peer, a hell of a lot more) and ignored the invite - that's a combat indicator right there (especially knowing the personality types of those individuals). It also accounts for a bias in numbers. Especially considering that we had 2-star direction that PWOs were to be made available to AHRC if they wanted to attend. The spent heaps of time in Perth and Sydney, and not one ship was absent from their home port for the entire duration of the study.
Again, haven't read it, but I will suggest every one of Morant's physiologically attributes and their suitability claims is bullshit. Certainly every claim like that for combat arms in the Army was wrong or pseudoscience. I'd love to see one actual, scientifically backed physiological attribute that makes females not suited for any job in the ADF. I haven't seen one yet. Ironically, the one that people thought would be a slam dunk (injuries at Kapooka) highlighted it wasn't a 'female thing', it was a diet and time thing, and the trials improved male and female injury and graduation rates. In relation to this topic - what job does a PWO do (mine, air or surface) that a female cannot do?
Honestly, the way PWOs act (especially to each other), the way the trade has handled workforce and the shortage in numbers implies that any senior PWO (and this sounds like Morant) should have no say in how the trade goes forward. To mismanage one of Navy's most critical trades to the point you make Air Force aircrew retention look perfect means that those senior PWO peeps should never have a say again. The fact that there were more O6+ PWOs than O1-O4 PWOs in the 2010s highlights (a) that senior PWO peeps are atrocious at career work and (b) that the trade desperately needs more people recruited - so cutting of 51% of the Australian population would be criminal.
Frankly, anyone who says increased females degrades ADF capability is so far out of date that they are a bigger risk to our overall capability. It is so pig-ignorant, wrong and illogical that I have little faith they could do their actual job in an increasingly complex world. There is significant bodies of work that highlight women in ground forces make understanding human terrain better, that having women in HQ makes for broader (and better) thinking, that women are better for anything that exposes them to G's and that women can think and react more logically under pressure. And not all of them come from the ADF, or even militarises.
Opening up all jobs to women makes the ADF better, stronger, more capable and more resilient. This is an easy win. It will be brutal seeing dead women come home (is it any less seeing young men? Really?) but if people think women won't be in the front line they have no understanding of modern warfare.
