Traffic from a curtain country while the webshop is in another country

Hi, I have a webshop in the Netherlands en we receive a lot of traffic from Australia - Sydney. Im absolutely sure that it’s not ‘real’ traffic. It’s daily traffic around 1500 sessions. It looks like a curtain system that is pinging our website. The sessions are on all pages, but with low engagement. Is there a known plugin within shopify who can do this or anything I can look into to see how I can stop this traffic. It shows in ga4.

Thanks
