The biggest problem is that the NSW Electoral Commission is holding secrets (the source code among other things). That's fundamentally at odds with a secure voting system. If the system is algorithmically secure, there should be no need to rely on the security of the NSWEC, past a set of secret keys. If the system relies on the security of the NSWEC then it is open to subversion by someone who knows the NSWEC's secrets. If the system is algorithmically secure, and the NSWEC is still not releasing information, then the NSWEC is simply undermining trust in its own system. I suspect that part of the problem is that the NSWEC is a bureaucracy, which has to justify its own existence. A secure on-line voting system, with minimal secrets, would largely make the NSWEC redundant on election day. The NSWEC need to accept that its job is to set up a secure system, then on the day relegate itself to a monitoring function on a par with any other interested citizen.
