Yep that's what I found too... was hoping to find a way to bypass the eligibility....
Can't see the point of it, it's free so why restrict it ?

Will have to source someone who uses it and get a decoder from him !!
(edit, I know you asked about VAST, but anyway...)
I haven't used it for a while, but you used to be able to get free Australian TV from PAS-8 (or PAS-2?), which I think may cover you. It is free (unencrypted) and seemed to be a mish-mash of current news, old tv shows, and some things from each of the commercial stations.
I was receiving it using a DVB-S card in a PC, and it worked fine. I am sure you can get satellite set top boxes that do exactly the same, but direct to the TV. I think even the ones that can decode pay-tv can be used with non encrypted channels, but I would check that first.
I don't know anything about this 'VAST' thing, but for a long time there has been "free" digital tv available across Australia. It was/is called Imparja, and is meant only for areas where you cannot get terrestrial TV broadcasts.
The reason for this, and the reason that it is restricted is.... advertising

Someone has to pay for these channels, so they want to make sure that you see their ads and not someone elses. This means that your local Sydney/Melbourne/Elsewhere stations do not want you to watch someone else's channels and not see their ads. I think there were also ads on Imparja, but targetted to rural regions of Australia.
I believe that you have to buy the smart card to get the Imparja service, but after that it is free. You have to prove you can't get regular TV, but there is no way of them knowing where the receiver is then moved to.
Of course, you then need to make sure you have adequate coverage/signal. If you are in New Caledonia, you would need to make sure you have coverage for the right transponders.
I haven't looked at this stuff for years, but somewhere you will find a list of satellites that you can 'see' from there and what you can get. I would not be surprised at all if Australia specifically broadcasts into the Pacific islands, and that it will cover you.
