The Black Rat has been categorised by the Australian Government as an alcho-pop, thus attracting a higher rate of tax than a standard Bundy & Coke. Thus, the Black Rat is often only affordable by the discerning, older drinker.
In the rare event the bartender is unaware that Black Rat is Aussie slang for a Bundy and Coke, an explanation may be required. Usually the explanation draws an appreciative giggle as a response, acting as a catalyst for ongoing excellent service. Often with cries from the bartender, "Hey Mate, another four Black Rats?" Now that's service.
The most popular rums in Australia are the ones found in Queensland in the town of Bundaberg. Rums that are made by the town of Bundaberg are excellent for mixing, such as the rums from Waterview Distillery and Bundaberg Distillery.
