Compressor is correct,
It has been answered correctly in the original thread. The blue belly aircraft is a C210, VH-ZIO. It is operated on behalf of Nearmap, and the flights are for the purpose of getting high res ground pictures. Look up the rego on flight aware, it is tracked flying the patterns you describe at 8,000.

Edit: It has a blue top, not belly, my mistake.
