In the case of CAGRO, as there are at Broome and Avalon, who employs them (ie airport owners and or operators) and are the employers absorbing the cost or are the costs passed on to the consumer plus a tidy profit margin? Because if that is the case then there must be a conflict of interest there at Avalon because the airport have stated that they do not want ATC?
I'm not saying that this is the case but maybe somebody, ie Dick, may have knowledge of how the CAGRO system works. To me it looks like private ATC but without the benefits of controlled airspace.
