What that is telling you, is that they lived successively in the suburbs of Brisbane called West End, New Farm, and Northgate.
These suburbs, which are all in the city of Brisbane, are about 2 km west, 2 km north east, and about 10 km north of downtown Brisbane.
These suburbs are ( or were at the time ), in the electoral districts named Kurilpa, Merthyr and Nundah, defined for electing members of the Queensland STATE Parliament. These are different to the districts for the Federal Parliament.
So, for example, in the first address there, you would be voting in the state election to choose the state MP for Kurilpa , and also at a different time, in the federal election to choose a federal MP for Griffith.
