Two things I ended up taking back from Byron Bay: a bag of Byron Chai mix (which is quite good; one of the better chai mixes I've tried), and a small jar of lemon aspen jelly (which tastes like lemons, only perhaps slightly more sour). Apparently lemon aspen jelly is made from lemon aspens (a native plant that only grows in Australian rainforests), and not lemons aspen (though it sounds like it should be).
maybe you could set up a chai stall outside Sahara - it would take very little to undercut their exhorbitant chai price...
