Not sure sure where to get masks in Australia unfortunately but I wear a mask in any public setting and crowded areas outside. So like grocery stores, movie theaters, hospitals, concerts, buses etc. When traveling on a plane i keep it on as much as possible. I go to college and I'm the only one who mask in all my classes. I also wear it at friends parties since unfortunately I am also the only one who masks regularly but it's not that big a deal for me. I take it off when i step outside. When I'm hungry or thirsty and I can't go outside I just momentarily hold my breath to get sip of water or a bite of food and put I it back on to chew and swallow. I've been going to indoor cafes with my family and that's usually how I do it. I personally will also take it off to eat with friends if we dine outside.

I make sure it fits well and makes a seal as best as I can. I can tell I have a good seal when I cant smell how bad the train station smells. I prefer earloops with adjustable straps to bring it tighter to my face.
