I had to do two things before I shut out overseas buyer completely.

First I blocked all overseas countries in postage settings, then I removed overseas post options from all my listings.  Maybe the second procedure would be sufficient by itself, but if you want to be sure, this worked for me.

This should take you to 'Manage Posting Settings'

     https://www.ebay.com.au/ship/prf

Near the bottom of the page is the option  'Exclude Postage Locations'   Click 'Edit'.

On the page that comes up, just  tick every box under 'International'

After doing that, I still had overseas buyers, and had to remove overseas post options from individual items. Fortunately you can do this in bulk (I can't remember if I could do this before I had a store, but I'll assume so.)

From your  'All Selling' page, tick the box at the top of your listings that selects all items, then click the 'edit' button.

On the subsequent page click 'Edit Fields', and select  'International Postage'.

Choose 'No International Postage'

After you've clicked 'submit',  it will remove whatever overseas postage specifications you have from any items.

I have also suspended international sales on my main selling account using the method highlighted above ( bulk edit ) but there is a sting in the tail. It only takes a few minutes to remove international post from your listings, but re-instateing it later ? 

If all of your items are different, its going to be a time consuming pain in the b*tt. You may have to edit each listing individually. what I plan to do is group similar items that I can search using key words in the title and bulk edit the international post on them. There will still be a large number that will need to be revised individually. With over 1000 listings on this account, its going to take several days to reinstate international postage.

I have left things as they are on my smaller selling accounts, cancelling sales with the reason " problem with buyers address " as I simply don't have the time to edit another 700 - 800 listings on top of the 1000 on the main account..

Like Lupercal, my Australian sales have increased slightly and this is helping to offset the loss of international sales, but with 30% of my sales normally going overseas, the local stuff has not completely covered the loss of international sales.

I have excluded international postage on my main account, but still have it as an option on my smaller selling id,s. Sent an item to the U.K. today and the PO advesed it will take a minimum of six weeks. Apparently a lot of mail is going by sea again as airlines have ceased flying.

AP must be rubbing its hands together at the moment. Charging full air mail price for international sea mail. Charging 10% more for letters but only offering half a service and taking forever to deliver all the extra parcels it is getting.
