Welcome to the Q&A Forum

I'm afraid there's no one "right" answer. Country-specific TLDs do have some extra power, but the problem is that then you're splitting everything - content, links, social mentions, etc. If you have the budget to really build up a site and market it in each country, then ccTLDs are great. If you aren't ready to go all-in, though, I'd probably recommend against it. I generally would not rely on machine translations. They tend to be a poor user experience and Google can often spot them and may consider them to be thin content. A good translation done by a native speaker is perfectly fine. In this case, I'd also use the hreflang tags to let Google know that it's a language/region-specific piece of content: http://support.google.com/webmasters/bin/answer.py?hl=en&answer=189077 Finally, in most cases I'd recommend sub-folders or sub-domains. Sub-domains may split authority and can act more like separate domains (but without the power of the ccTLD). There are standard practices for sub-folders, like "http://www.sepndbitcoins.com/au" and "/nz" - and this can help Google more easily understand the site structure. If the pages are all in English then I'd definitely recommend hreflang tags - they'll help Google sort out the region-specific content. You can target sub-folders in GWT.
