It all comes down now to personal evaluation of risk, cost (not financial but lifestyle, convenience etc) and benefit. If you're stressed about catching COVID, you can wear an N95 and/or limit your exposure by adjusting your social and travel habits. Use in medical and aged care facilities seems sensible. I kept wearing them in shops etc until the rules were changed very recently, but my observation is that compliance was tailing off quite rapidly. If I was doing a daily commute by train or bus I'd give consideration to wearing one on there.
The government have a tricky balance to attempt between what is scientifically best, what is socially acceptable and what is good enough.
