The phone was announced 17th March 2022 and released 22 April 2022.
I would suggest to keep checking in on your Samsung Online Shop Site and via the https://news.samsung.com/global/ for further information when it becomes available.
There maybe independents in your region that may sell the phone but be sure they are selling real Samsung phones and not clones, and if you decide to import one be aware certain features may not work or work properly such as Samsung Pay , 5G , Samsung Members App and the 2 year warranty may not be applied to an import.
As an alternative perhaps look to see if there is another model close to the one you've seen that ticks your wants and needs boxes.
I wish you all the best.

The advice I offer is my own and does not represent Samsung’s position.
I'm here to help.
I think the way the a73 has been released is really poor, no dates, no areas listed where it is available and no areas where it will be availsble from official samsung sources. It is like they have nk respect for the customers!!
Samsung are keeping quiet on this, when I was on the website I used the chat function to aske if tbe A73 was being released in the uk, the answer was "just buy an a53"
I have seen a list on a review site that lists UK as a release area, but not when. Not sure how reliable it is but would prefee to buy of Samsung rather than the ones appearing on ebay, amazon and Google
