Massdrop is currently dropping Oakley Carbon Shift (non-polarised though) for USD99 plus USD9.95 shipping, totally just under AUD140. The Shift is listed on Oakley website (au) for AUD 389.95.
It even includes an Oakley hard carrying case. In my opinion, if you are after a pair of "low-profile" "good looking" (very subjective) good brand sunny, this might be what you would like to consider.
Copy & Paste:
Designed to look great, fit great, and stay put, the Oakley Carbon Shift sunglasses feature a unique combination of materials: O Matter (a durable, pliable plastic), plus aluminum and carbon fiber on the arms. This makes for an incredibly lightweight pair of shades, despite their size and full-coverage lenses. The gray High Definition Optics lenses complement the matte black frame, and are held in precise optical alignment by the company’s Three-Point Fit. Meanwhile, the Unobtainium earsocks provide superior grip, so you can walk, run, or ride without worrying about your sun protection sliding off. A microfiber bag and hard carrying case are included.
