Detective Pikachu may be getting an international release to tie in with its live-action adaptation.
Pokemon fansite Serebii.net has spotted that Detective Pikachu has been classified in Europe with a placeholder release date.

We were unable to find the listing on the PEGI website. At this time, it does not appear that Detective Pikachu has been submitted for classification in Australia.
The 3DS title has players running around town solving mysteries. You're accompanied by the titular Detective Pikachu - you can tell he's a detective because he wears a deerstalker - who you can understand for some reason and is the most entertaining part of the game.
