Speaking from a purely self-serving standpoint, I'd be enthusiastic about it.
Primarily, I will admit, because I'd LOVE to be stationed there and experience some of the unique hiking the Oz natives on this forum keep raging about. Tasmania fascinates me.
But beyond that I will refrain from comment, since this is more of an issue for said Oz natives to decide upon. Certainly there would be benefits for Australia, but also costs, and I've seen how 19-year-old Marines behave.
Ew. Marines. What can you do, right?
