Yes it never ceases to amaze me, of the lack of radar obs in areas of low population, we used to live and work in a mine just west of Tennant Creek, many years ago, so l know the area well.
The we lived in Eromanga, sth west qld, same deal there, no obs in any of that country, it's appalling really, for the safety of travelling tourists, and workers, never mind the hundreds of local people that live in those areas and Oil Well Staff, that would be jolly happy to know if rain is coming by being able to look at a radar image, the whole area around Birdsville is terribly neglected, and that is a major tourist route. l at least rallied for online floodway indicators for some of the creeks in the Eromanga area.
Major cities are the winners in all aspects, including communications. The governors and councils wants people to live out in remote areas but there is no incentive to do so.
