I'm not Australian, I don't drink beer, and idk what I'm saying so I need someone to tell me if this sentence makes a lick of sense: "Eddie’s carrying a slab because she doesn’t want a repeat of the last time she’d tried a beer at the Bush Wolf."

Is a slab too big? We call it a two-four, I think. It seems excessive, but again, I don't drink beer and the alcohol content is pretty low?? I mean she's not gonna drink the entire thing. I was gonna put sixer but I'm not sure if that's a thing. Do you all say beer? There seem to be 104 other terms I could use, some of which seem to imply that nobody actually enjoys the taste of beer which tbh has always been my suspicion.
