Online Direct Democracy - (Empowering the People!) and VOTEFLUX.ORG | Upgrade Democracy because both are making a very similar pitch. Instead of having an elected senator make decisions on how they will vote, their senators will vote according to the public will as determined through online voting. Given the recent brexit vote, I'm not sure how sold I am on direct democracy for everything.
Both parties are promising to have their system up and running in time for their candidates to take office if elected, but neither are fully operational at the moment. Neither provide much reassurance as to how they will get people to become involved, and how they will ensure that those involved do constitute an accurate representation of Australia as a whole. I suspect they'll tend to attract the young, tech savvy demographic but ignore the older non-tech savvy generations (I can't see my grandmother who still has dial up getting involved with either).
Finally, I'm concerned about the security & privacy implications of their systems. To be as auditable and reliable as they say they will be with systems that are not yet implemented and tested, I'm worried it will be possible to see people's voting history, and that the systems won't be as secure as they claim.
