As mentioned above, the general masks are for catching droplets that you expel. Won't protect you from other people's coughs but will offer 'some' protection to other people from your coughs.
IMPO you can't rely on others to mask themselves. Given that there's a high enough percentage of the population that don't care about others, I actually wear two masks when going out now.

One has replaceable N95 filters in it but it is exhale valved, so it will catch airborne particles before I breathe them in but won't offer any protection to other people from me if I'm sick and don't know it. Then I pop a disposable surgical mask over the top. As mentioned above, offers me no protection at all but is to protect others and I can throw it out when I'm done shopping/whatever.

There isn't going to be much that offers 100% foolproof protection but isn't it about reducing risk? And we all have different levels of what we consider acceptable risk so what I am happy with is going to be different to what others are happy with. Sure, I could catch it via my eyes but there isn't much I can do about. But avoiding indoors spaces and groups of people is what I'm comfortable with at this stage. If I were in victoria it'd probably be different but I'm in qld so at this stage I'm not about to go and put goggles on.

Though I do keep little spray bottles filled with metho/water in the house and in the car and spray anything suspicious like parcels from vic/nsw. Probably worth spraying the bottoms of your shoes too as droplets are going to fall to the ground and get walked over.
