Take your pick of colonial powers, one of them would have ended up here. Better or worse than the Brits? History would be a pretty good guide on that. Suggest that things are far better for the colonisation than they ever would have been regardless of another colonial power or no 'invasion' at all.
The money spent on indigenous 'issues' is staggering for extremely poor outcomes, an inconvenient truth.
For every indigenous leader wanting more welfare, handouts, land rights etc there is an indigenous leader wanting an end to more welfare, handouts etc.
Things will never change until the level of violence within indigenous communities is acknowledged and addressed, another inconvenient truth for the clowns jumping on the invasion day bandwagon.
