Welcome to the Q&A Forum

I have a website which services various countries, specifically the United Kingdom and United States of America.  I am now expanding the target of my website to focus on Australian and South African customers. The structure of my website is www.websitename.com/us/ for the American audience. This is also what appears on a Google search when browsing in the USA. For the United Kingdom we use just www.websitename.com which works and shows in the UK. When I have created the new versions which are:
www.websitename.com/au/
www.websitename.com/za/ I go onto google search my company and still www.websitename.com shows (When browsing from the relevant location). When it should show the /au/ or /za/ versions. I have submitted the relevant sitemaps to Google Search Console. Yet still from Australia and South Africa the .com version of the website it what shows. Please offer any advice to how I can get the correct version of the website showing in the correct location?
