New Barcode Required?

Good Morning guys,

Hope everyone is doing well. I am new to the UK market and have been selling in Australia for some time. Actually, I am confused about the barcode thing. I currently have a product selling in Australia and want to list the same product in the UK marketplace. Do I need to get another barcode for that or it will be the same as the current one? Please advise!
Thanks in advance😊

Thanks
