Indigenous peoples globally have problems adapting to colonialisation and in that respect our indigenous peoples are no different.
To expect Aborigine people to jump from Neolithic existence to post Industrial 21st C existence in 300 years is an unreal expectation IMO.
Just look at the South & north American indigenous peoples. They are struggling to make that ages leap (stone to bronze to iron to feudal to industrial to post industrial)
IMO their quest to preserve their traditional stone age hunter/gatherer culture is their advancement handbrake with very few biting the bullet and adopting modern culture and prosperity.
IMO its a package deal: Conform to modern values and benefit from those values or conserve the traditional Hunter -Gatherer values and cop the consequences (a struggle to survive) where the aborigine male is the apex predator.
