JB HiFi is sold out of the Midnight color, so looks like Spacetalk is offering free accessories with their less popular color Mist (Ozbargain's image shows the blue version, but the offer is on the green mist version, which has a neutral light grey watch face and green straps). Bonus charging kit is a great deal and then you can swap the watch band out for the standard midnight grey.
Much better reviews on the Adventurer (4g, bigger battery, water proof to 1m, released in Dec) vs the original Spacetalk watch. Telstra also started selling the Spacetalk Watches, but their SIM plans are too expensive (get a woolies SIM for $10/month and receive 10% off a grocery bill per month)

Monthly cost is ~$16 ($10 sim + $6 app fee), but the 10% off a grocery bill will easily offset it.
