Apparently the current charts for much of north western Australia are still based on the survey conducted by Mathew Flinders in a small open boat during his curcumnavigation of the continent at the end of the 18th century. I suspect that GPS is showing up the failings of many old charts, apart from map datum inconsistancies.
