The Australian accent is one that is very hard to nail down, I know that. But getting it wrong is just so bloody aggravating. Simple solutions: A) If the character doesn't have to be Australian, then just don't make them Australian. B) Just hire an actual Australian! Hollywood is full of the bastards! C) Hire one of the like... 3 actors who can actually do the job outside of these two options. Kate McKinnon is not one of those 3 actors.
...Oh and also Rough Night was not very good.
Final rating:★½: - Boring/disappointing. Avoid where possible.
