International SEO - 3 ccTLD's

[AUSDigManager]

HI,

I have three websites with .net.au, .co.uk and .asia
The 3 have duplicate content on many pages for the same product.

Do I also have to geotarget in GSC, or them being ccTLD's is that enough?
Should I use hreflang?
Any other advise would be great.
Thanks

If same content using on different ccTLD like  then that won't be consider as duplicate content if you are targeting different countries. If two pages have the exact same content, Google won't want to show both to the searcher. They'll pick the most relevant one, or perhaps the one that Google has decided is the originator of the content and show that one.

You can go for hreflang. that will be useful.
