I have an understanding of the region locking that applies to the PS4 (DLC will only work with a game disks from the same region and DLC codes are locked to a single region)
I understand that America and Australia are treated as completely separate regions on PSN.
However I am confused if other PAL terrorises (UK/Europe) is treated as the same or completely seperate regions from Australia. Have read conflicting information online as to which is the case.
Specifically I wanted to use a European DLC code with a European game disk on my Australian PSN account.
It's very rare that this happens. If worse comes to worse you could always make a psn account under a UK alias, redeem it, then switch accounts. This shouldn't be needed though
