The NSW government and the Federal government fail to accept responsibility and accountability for this utter debacle, preferring to point the finger at each other. No leadership at all. They must fear what is going to happen to them because of this.
Reminds me of the NSW government and the dangerous iPad chargers being sold. An innocent young woman was electrocuted and they lied to the public to protect their own own arses.

We should get Bill Gates involved. The guy has been fighting viruses since Windows 95.

And everybody coughs now and then, maybe because the throat has become dry while talking. It's known that the virus replicates mainly in the throat during the initial phase of the infection. This is where the main virus load comes from, and this is the main transmission vector before symptoms begin to show. The virus spread in Berlin mainly through clubs. On the dance floor, at the bar. Loud music, you shout into the face of your peer because he/she cannot hear your otherwise - bam.
After the coughing and sneezing starts, the risk for transmission through smear infection comes from coughing and sneezing into your hands and then touching stuff or other people. This is what the WHO recommendation is targeting. Not only through washing your hands but also through "sneezing and coughing hygiene" (into your elbow, not into your hands, because you don't touch door handles and other people with the inner side of your elbow).
I'm aware of that study that suggests the virus easily survives days on plastic or metal surfaces and stays active. This has been demonstrated in the lab only, by infecting bacteria cultures in a petri dish. It's not yet clear how/if this study can be transferred into real world risk. The study only shows, if you put a droplet full of virus onto a plastic or metal sheet and then let it dry for a certain amount of time (some hours, days) the virus is still able to infect a petri dish full of bacteria in optimal environment.

I have no doubt the WHO is aware of this. It seems likely this is why the WHO recommends social and physical distancing. It's easier to implement, more foolproof and less likely to backfire and less of a burden on resources.

You didn't address any of what I just said above.
I linked to the recommendations of the WHO that clearly imply that masks are to be used if you may be infected, or if you're dealing with someone who is. The WHO you keep mentioning writes that. Have you actually read what they say?
The only thing I'm questioning at this point concerning what they say is that they seem to restrict the use of masks only if you or someone you have to be close to is infected, and my questioning is because there are likely a lot of people not showing any symptom but that are also clear potential vectors.
I do not agree again that only if you cough or sneeze heavily you're a hazard. We keep emitting very small droplets all the time without noticing it. And anyway, we may just cough or sneeze randomly without being able to control it just because of dust or anything else. So my point is NO you don't have to have developed clear symptoms to be contagious.
Now given the scarcity of masks, it can make sense to be cautious about promoting them unreasonably. This is risk and resource management. I personally think that if they had recommended for everyone to wear masks regardless of their condition, this would have triggered an uncontrollable panic as we just can't provide them. That I understand fully. I also agree with the point that most people don't know how to put them on properly, but still think some barrier is better than none at all.
For the rest, I again haven't seen in the WHO recommendations a clear point saying that masks are useless, since they recommend using them in the above cases.

As Amazon Prime member I’m used to free 2-day and even next day delivery. I browsed Amazon for few things yesterday and today, and I’ve noticed that many items had magical delivery date of April 22. Some items were still available for delivery this or next week, but most had that strange ETA.
Is Amazon shutting down some of its distribution centers?
