There's been some controversy recently over the two Boundary Streets - one in the West End and one in Spring Hill - in inner city Brisbane (as can be seen in this 2016 article, where the Mayor seems open to changing the names). The article is quite vague, however, about what those street names really represent, and what occurred in colonial Brisbane between British settlers and the local Murri people who are the traditional owners of the land. What is the history of those streets?
The history of those streets is, very briefly, “night curfews”.
To get to there though you need to know more about the history of the area from before white settlement onwards. Brisbane is in the Moreton Bay area. That area contained at least eight aboriginal language groups which might be considered separate tribes. These “tribes” occupied areas that were patrilineal but had access to other resource areas on a matrilineal basis. Marriages between close relatives were forbidden and so wives could come from a considerable distance making the separate “tribes” inter-related. The tribes often traveled to particular common locations to peacefully share resources like bunya nuts or fish runs at particular times of year but they also entered each others patrilineal locations to fight.
The first European settlement in the area was the Moreton Bay convict settlement. This was one of the early punishment settlements for internal exile of intransigent convicts who had been already transported to Port Jackson (Sydney). i.e. Convicts transported from the United Kingdom to Australia. In 1824 it was established at Humpybong but there were problems with the aborigines stealing flour sugar and tools and attacks on individuals. In 1825 the settlement relocated to the Brisbane river, a place that was considered more defensible . The 1829 government regulations section 35 included in other powers give the Commandant the authority ‘to remove at his discretion, any Free person from the Settlement, who's Conduct shall appear to him to render this proceeding necessary for the due maintenance of discipline.' A free person in this sense is anyone other than a convict or a soldier and includes aborigines. This appears to be the authority which was much later used to enact curfews. There continued to be clashes with aborigines. In 1829, Captain Patrick Logan, Commandant since 1826 and notorious for his harshness against convicts, separated from his party during an exploration trip and was killed by unidentified aborigines. In 1840 three members of a survey party were attacked with two of them (Stapylton and Tuck) murdered and the third (Dunlop) severely injured.
In 1838 the area was first opened to free settlement resulting in the winding down of the convict settlement. In 1842 the town of Brisbane was surveyed and in 1846 its town boundaries proclaimed covering roughly one square mile bounded by Vulture Street, Wellington Road, and the two Boundary Streets. Clashes with aborigines continued with settlers regularly complaining that whenever large groups of aborigines formed through non-local groups visiting, either for ‘corroborees’ or to fight with local groups the result was that the outsiders would raid the local farms and enter the suburbs and town to steal. Complaints also centered on aborigines getting drunk in town and then roaming the town at night and on young aboriginal women prostituting themselves for drink or tobacco outside hotels in town. In or about 1856 there was established a curfew preventing aborigines being within the declared boundary of the town after 4pm and all day Sunday. It seems to have been intermittently observed and enforced, partly due to insufficient police but it is mentioned into the late 1870s in newspaper reports and letters that mounted policemen are enforcing it.
So the curfews aimed at keeping aborigines out of Brisbane town and away from alcohol at night lasted for at least 20 years and are associated particularly with the two Boundary Streets mentioned as they formed part of the declared town boundary.
This is not a complete discussion of clashes between Europeans and aborigines, simply an answer to the OP’s particular question.
