More seriously on naming, Australia has a history of avoiding using people, for good reason. I think (tell me if I'm wrong) we only ever deviated from this for the Collins submarines.
I believe that ship name choices are part of our fundamental military licence to operate. We must always be seen to act and protect the community, not individuals.
Naming after people is hazardous, as it can become polarising, either views that somebody else was more deserving, it's too bias to a particular group, or that person is associated with a problematic view or action.
Politicians are a terrible choice, as regardless of who it is, part of the community will always have an automatic aversion to the name and it instantly becomes divisive.
Using places is far less volatile, and it links broad communities, rather than individuals, to the defence force. Choosing a city, river, mountain, harbour or other notable geographic feature is rarely ever controversial.
It might be boring, but that is not the requirement.
