Down here in Aus, we have, off the top of my head:
Lays (I think these have been phased out actually!!)
Smiths
Thins
Ruffles (very hard to find)
Samboy
Cool healthy ones like GRAIN WAVES (these things are amazing)

Corn chips wise there's Doritos and CCs but yeah. I don't know why I am posting this!!
