I am looking to launch my personal portfolio site soon and at the moment I have registered a .co.uk (have had this for some time) and recently a .com domain. I have just moved to Perth, Australia and will be living here for at least the next few years. When the site is launched I will be aiming at attracting clients in the Perth area, as well as Australia wide. Should I use the .com domain or should I even look at buying a .com.au domain?
The reason I am doubting using a .com.au domain is incase I go back to the uk after a few years. If this was the case, would using a .com be a better option? That way if I return home I could still use this domain and I would only need to change the site content to reflect that I would no longer be based in Australia, and then re-optimise it for uk based searches.
What are peoples thoughts on this?
