In Melbourne I have literally never had anyone at any cafe, food stall, or any other similar place ask me for a tip, and yet every single one of them have a tip jar. The tip jar is always filled with silver change, almost always a "round up" from a note. If I buy a coffee for $4.20, and pay in cash, the tip jar might get my 80c. (I almost never carry cash, so this is rare in and of itself.) The only time I've ever even seen a tip requested is as a part of some POS card readers, where it asks if you would like to leave a tip before you enter your PIN -- Conversely I've also had employees tell me "just hit enter to skip the tip bit of the transaction" before I've even gotten to that stage.
