Incorrect country currency/prices showing on Shop Page

Hi,

Having issues with unrelated currencies showing on our Shop page. For example, a customer on the website in Australia is seeing Euro prices on the Shop page, but when they enter an individual product page the price changes to the correct Australian price. It should be Australian pricing and currency throughout. This is happening on a Safari browser and not on Google Chrome. Have not tested other browsers.

The only change we have made recently prior to this issue was updating WooCommerce to the latest version. Prior to this, there was another issue with all prices showing in the correct currency on the Shop page but two products displaying USD prices once they were clicked on by an Australian viewer.

If you could please advise at your earliest convenience that would be greatly appreciated.
