South Australia is currently consulting on draft laws to cap political donations, but there are potential constitutional issues and practical shortcomings with the proposed laws. It doesn't adequately kerb third-party campaigners, which could create a problem similar to America has with the creation of PACs/Super PACs. There have been previous High Court cases which have made it harder to block third-party campaigners, but Anne Twomey here thinks a more carefully-targeted law could be constructed to address this problem rather than ignoring it entirely.
