If they are myths, why bother wasting time (and the ANC/TNC payers' money) busting them?
Some of the points made don't address the "myth". What does the agreement of a bunch of alphabet soup organisations have to do with the costs of equipment and installation or the objective benefits of the mandate? Nothing. (And have the representations that were made to those organisations in order to obtain their agreement been delivered upon?)
Citing opinions of the ANSP in the US as authority for propositions about ASD-B is a joke. Here's what the independent Office of the Inspector General of the US Department of Transportation had to say about ADS-B:

Just imagine how many very expensive lessons will be learnt and improvements made by the FAA leading up to and post-mandate, which costs could be avoided and improvements 'borrowed' by Australia if Australia waited.
When the highly-paid execs in Airservices can manage to build an organisation with around 900 excess staff out of around 4,000 and not make money out of a monopoly, just imagine what they'll do with ADS-B implementation. (And don't get me started on OneSKY....)
