Murray Whelanseries by Shane Maloney - Murray is a political aide to a labour MP in state parliament who has to solve a murder before it (generally) brings down the government or he gets murdered. Also a series of films startting David Wenham (and directed by John Clarke)
Death in Brunswick by Boyd Oxlade - it's set in Brunswick and is a little weird to be honest and the main character is definetly not likable. Movie stars Sam Neill and John Clarke co stars
The Holiday Murders by Robert Gott - set in 1943, there's 4 books in the series (though by the end of the second book I was done with it). There hasn't been a movie about this one, presumably because John Clarke didn't read it
Don't know that it's necessarily what you're looking for but Feather is basically an open world flying game and is very chill.
