Mr. Neil McDonnell:

We are suggesting a geo or location-based or sequenced postcode that gives adjacency to addresses, that is, a postcode which states that address one is beside address two. How precisely that is presented is technical and is irrelevant to us but we simply need something like that. The reason we have appended four different examples to our submission is there are functioning proprietary systems available right now. We do not advocate any particular solution and do not even state it must be one that is in the back of the pack. We simply are stating there are lots of clever people who already have come up with excellent solutions to this and it cannot be beyond the imagination of the Department of Communications, Energy and Natural Resources to put in place a similarly productive useful system.
