This is a GoDaddy Blog post, so it shouldn't be a surprise they rated GoDaddy number 1.  In our experience, they aren't the cheapest or fastest option for Australia.  Siteground is... at least for your first year.  But their support and member help IS.  Even if, like us, you initially use them and then transfer to a different host, their offerings in terms of domain registration and domain emails are excellent.  BE WARNED if you change hosts your website and potentially emails won't work for around one to three days.
