Paramount+ and Showtime are both owned by the same parent company but in the US are separate services. There they've announced a combined $12 a month bundle or $15 without advertisements.

Here in Australia, Showtime content had been with Stan but moved across to Paramount+ after that service launched.

While there has been no announcement of Paramount planning to charge ozzies extra for Showtime content that might be something to watch out for.

Having to pay extra to not see advertisements also sounds like a stinky possibility.
