Dynamics CRM 2016 comes with tons of new great functionalities. One of them is Address Auto Complete.
When you enter address details, CRM will try to complete with a pop-up. If you want to see how it works, dynamicscrmcenter wrote a nice blog. http://dynamicscrmcenter.com/2015/12/13/crm-2016-postal-address-autocomplete/
The only issue with this in my opinion is that it default it searches to US addresses. So for those live in a different country just get annoyed by it. I was unable to find any settings to change this behaviour (if you know, please leave comment below!).
So to change this behaviour, I resorted to using Business Rules by defaulting the Address Country to Australia.
