Yesterday's copy of WILD magazine has a sizeable article by my old bushwalking mate John Poppins reviewing 10 current GPS from a bushwalking point of view. He makes the essential point that Australia has TWO different datum sources depending on the date of your map (I believe that someone re-established Sydney Observatory, so that some of the maps now have a gap between them - or perhaps an overlap, but I haven't seen that yet).
