Unrelated, but from the guys I've talked to who worked at Bing Lee, they're not particularly happy with working there (this is the Hornsby store; don't know how well that generalises to other stores).
Edit: Just a thought, it should either be award wages, in the contract you sign, or an EBA (another type of agreement)... It'll be somewhere if you do the research enough. I'd imagine if you can't find any special "Bing Lee" agreement, you're probably looking at award wages.
