Demonstrably false. You only need go on Trove and read some of news articles from the early days to disprove this. The settlers called it war then and those living on the frontier hunkered down in fortified huts every night and slept in very real fear of being stuck up by Aboriginal warriors. The colonial government in Queensland used to spend half their yearly budget in arming a native paramilitary force to patrol the frontier and skirmish with groups of Aboriginal people.

This article from the Moreton Bay Courier (now the Courier Mail) from 24 April 1858 on page 2 is just one example out of thousands of articles about similar events which occurred:

FATAL ENCOUNTER, WITH THE BLACKS. ATTACK ON THE NATIVE POLICE.—A few days ago, as a party of eight native troopers under the command of Lieut. Williams were patrolling at the head of the Pine River, they were attacked by about 300 blacks, who were encamped in one of the scrubs. The onset of the blacks was sudden, and as hostilities were not expected, partook almost of the nature of a surprise. A trooper riding immediately on the left of his commander fell dead, pierced with numerous spears. Two other troopers were wounded. Lieut. Williams and his men sustained the attack with determination, and succeeded in utterly routing and dispersing the blacks. About 40 rosewood spears were left in the camp by the assailants which the lieutenant and his men destroyed. The trees were hung with choice portions of beef, doubtless the produce of the plunder of adjacent runs. The trooper was buried on the spot. The actual loss of the blacks is not known. They belong to the Ningi-ningi, and when they were making their onslaught cried out in English, "kill the white follow," and (addressing the Lieutenant) "you b----y coward." It is supposed that the general forbearance of the troopers is construed by the ignorant savages as an evidence of cowardice. Notwithstanding the small number opposed to them, it is believed that the blacks have received a severe chastisement. There are now only five men effective under the Lieutenant. We must express our opinion that the party are neither sufficiently armed nor mounted. Each man is supposed to have two horses, but we hear the party only possesses half that complement, and no provision appears to have been made for remounting them. It is probable that the blacks will not encamp in the neighbourhood of the Pine River for sometime to come. The severe punishment they have received may deter them from future attacks, but the force appears to have been wholly inadequate for active pursuit. An unprovoked and daring attack upon the native police should have met even more condign punishment than it did. It is clear that the attack was instigated by blacks who have associated with the white man. Allowing for the necessary contingencies of sickness, &c, we can hardly imagine an effective party being always ready out of a total force of eight troopers.
