True, the realities of an attack would be very different from the way she presents. But the role of the military representative here is to see through the incorrect, or overly dramatic examples of the public and address the core underlying fears. From this reporting, i don't think they executed on that at all well.

Your Live music example is interesting comparison, but its not exactly comparing apples with apples. Thats because live music is far less destructive than a militarised attack however more unlikely a militarised attack over live music is.

It puts in mind of the comparisons between solar/wind/batteries, and nuclear. Yes they can all be far more 'green' than coal, oil, and gas, but, again however unlikely an event occurs is, the destructive capability of a nuclear accident is far greater than that of solar/wind/batteries.

I don't know why but this comes across as such a bitch complaint to me, like living next to a live music venue and complaining about the noise

That's an apt comparison. The naval base has been there since the 70s. And before that, HMAS Leeuwin was 20km north at Fremantle from 1940.
