I would like to know if Virgin Australia intends on becoming an alliance member...?

Maybe Star Alliance with NZ and SQ?!

IMO if they ever considered joining one, I think they would either join Star Alliance becuase of NZ & SQ or Eithad Airways Partners (Etihad's Own type of Alliance)

Colski101, you can never rule out anything, but I'd rate the likelihood of any joining Star Alliance or Sky Team is practically non-existent. Just like Etihad and Emirates prefer not joining such programs, VA has followed suit. If anything, there is more likelihood VA might get progressively closer to Etihad.

I think the way to force Virgin into moving one way or the other is to have a viable 3rd independent national carrier offering a domestic network that matches Qantas and Virgin.

At the moment, unless you're a rusted on Qantas or Oneworld customer, your only real choice besides Qantas is Virgin, i.e. Virgin doesn't need to align itself formally into an alliance to get additional business. A 3rd domestic airline would split the "Qantas residual" market and provide impetus for Virgin to align itself formally with an alliance to lock in sections of the market with a pre-existing relationship with one of the remaining non-Oneworld alliances. 

In a way, Virgin's informal alliances with Etihad, NZ, SQ and Delta is quiet smart as it forces a fragmentation of the "Qantas-OW residual" market, which forces this segment of the market to behave in term dictated by Virgin to reap the most value.
