Combining the NBN and "boat people" (for Aussies)

So the election has finally been announced and I've thought of an idea to solve these two big problems.

1) The NBN under Labor will be "fiber to the home" (something that would serve Australia very well in the future) but under Liberal will only end up being "fiber to the node" (nowhere near as good but of course much cheaper).

2) Both parties want to stop the "boat people" (despite the fact that tens of thousands of people arrive by plane and stay in Australia illegally due to overstaying their visas - but whatever as a nation we seem to *hate* boat people).

So why not have a policy that says: Provided you are not discovered to be some criminal that should be sent back to where you came from you can *earn* your Australian citizenship by working on the NBN rollout for 1 year?

If you look at the past you'll see that huge projects such as the Snowy hydro project and even the Great Ocean road project were basically done this way in the past.

This would greatly reduce the cost of constructing the NBN and at the same time provide a place for new immigrants as has occurred in Australia's history (and no-one these days complains about immigrants who helped with those earlier projects).
