I work in CBR airport, few days a week, and I see that almost 80% of the pax don't have a mask at security or when roaming about the airport. No one is enforcing pax to wear a mask when in the airport. They are "suddenly" reminded that they need a max when their flight is boarding. They rush to the retain outlets in the airport asking for a mask.
When QF does a boarding announcement at the airport, the announcement reminds pax that wearing a mask & practising social distancing is mandatory when scanning their BPs, waiting on the bridge & when in the plane. There is no mention of wearing a mask when inside the terminal. Masks must stay on for the entire duration of the flights. Masks can be removed briefly when eating/drinking.
VA boarding announcements - if I had observed correctly, don't talk about masks or social distancing. They call elites, those that help boarding to come forward. No mention of masks or social distancing.
I don't think Pelican, Link or Rex announcements make any mention of the masks or social distancing.
A few months back when flying out of CBR, I have seen both airline staff, security & at times, AFP patrolling the terminal, reminding pax to wear a mask. This doesn't happen any more.
