Wistari Reef is a lagoonal platform reef, situated on the Tropic of Capricorn, within the Capricorn and Bunker region of the southern Great Barrier Reef. Fives cores were collected and analysed for 14C radiocarbon dating, sedimentation rates and granulometry data. The effects of bioturbation within the cores was pronounced, and as such ages were likely to be undersestimated for deeper samples, and overestimated for shallower samples. From the results, the oldest age estimate obtained was from the base of core VC-01 and was aged at 2150±70 yr BP. All core tops were estimated to be ~1100±70 yr BP. The biggest maximum rate of accretion was seen at core IC-02, which exhibited an accretion rate of 4.79m/ka. The smallest minimum accretion rate was seen in VC-02 (on a sanded reef flat) with a accretion rate of 0.57m/ka.
