Ladies, where do you get your pads? And what common brands have the best, biggest pads?

I’m living in Australia rn for grad school, and for the most part it’s great! But I’m used to going to the grocery store back home and buying a single back of full coverage pads to keep my underwear clean for the next 6 months, and all I’m finding around here are little packs full of little pads. Am I looking in the wrong places?
