So what is the actual change? Are the mob in Merimbula the only issuer now? I assume that means that RA-Aus won't be processing them too?
This link shows all the issuing bodies. Some will issue to individuals not directly employed by or associated with their airport or organisation, others will not.
There are some big changes in the pipeline for applying for an ASIC. The main one being that at some stage in the process, you will be required to present in person to verify your ID before the card is issued either to the IB or their nominated agent/s. This will be either to submit the application or collect the card. At the moment, many IBs accept applications by post with documents verified by the usual suspects. A national audit identified a number of flaws in this arrangement and before anyone jumps on their soapbox screaming blue murder, this was argued by industry for the past couple of years but the department is standing firm.
