A novel approach to funding a High Court challenge

I just stumbled upon this site which is seeking financial contributions to fund a High Court challenge to the validity of federal legislation. The impugned Act provides federal funding to schools for a chaplaincy program. I haven't seen a site like it before.

It is worth noting that, as far as I know, Queensland (the resident state of the website) has not abolished the common law torts and offences of maintenance and champerty, as some other states have. I am not saying that this site is even close to violating those rules, as it is generally considered an exception to the rules against maintenance to offer funds charitably (and each person funding the High Court challenge is likely to have as much standing as the person who has started the website). However, it is interesting to think how the internet might be used to coordinate more profitable litigation funding investment opportunities.
