How a white beach is sampled and judged

    The sampling rules, agreed in March 2006 by the National (Australian) Committee on Soil and Terrain, are:
    1. Current marine environment
    2. Wave action (swash) zone (i.e. not dunes)
    3. Sample must be representative of the beach
    4. Each sample bulked up from five equal sub-samples at least 10m apart
    5. Sample taken from the surface 10 cm
    6. Nothing can be added to, or subtracted from, the sample
    7. Sample cannot be treated in any way
    8. Within legal boundaries of state/territory

    Judging was initially conducted by comparative visual assessment by a random goup of indiviuals (>10)
    Subsequent spectrogaphic analysis has confirmed the visual results
