Hey Guys,
I have currently got two domains alfahosts.com and alfahosts.net

We use alfahosts.net as our main advertising domain but we registered .com so we had it there and no one could buy it.

We are now thinking of getting a .com.au or .net.au. I only want to get one. I have these thoughts:

alfahosts.net.au : Relates to our main domain alfahosts.net but not common.

alfahosts.com.au : Is popular but doesn't sound right :P

Your thoughts?
