You'd have to ask them, I've not worked at one.
Pay scales in non-chain stores (ie not Coles etc) differ from store to store, industry to industry, employer to employer et cetera. They also change based on your age, position and experience/qualifications. If you're a smooth talker you
just might be able to squeeze a few bucks extra for being bilingual (specifically looking at
native level fluency in Japanese or Chinese). Don't ask me much more though, because I'll have to admit ignorance.
