Be careful with outcomes based achievables. Its a nice sounding phrase, but as the Abbott government, and their successors found out when they introduced and favoured the Indigenous Advisory Council, (to the detriment of the National Congress).
Without the buy in from the people themselves you get no where fast. A body and decisions about your life foisted upon you by a distant and obscure leadership leads to poor putcomes and decision making.
A different example, to illustrate my point:
I and my peers were once forced to learn Indonesian when the school had other subjects available and a notional choice. The Principal decided the enrolments in Indonesian weren't high enough. So all students from the primary school who'd learned Indonesian were told they must carry on with Indonesian while the rest of the year could pick. Suffice to say little Indonesian was learned in the years following, and few teachers stayed due to their inability to control a student body who were made an enemy in their own education. I'm not saying the student body were right in how they acted, but the source was an out of touch decision by a distant leadership.
Back to the Abbott decision:
In the case of Abbott's direct outcomes based solution all the money spent seems largely wasted, as the larger population indicators over the period have all deteriorated quite dramatically.
This is a key reason why the structure of the Voice was so important. The model proposed in the calma*, langton report went a long way to ensure fair representation of all Aboriginal nations across Australia. (notice i say nations, not people. There was a glaring omission by both sides about the guarantee of personal democratic rights that was never addressed in the campaigns).
Anyway, here i've gone rabbiting away again. Suffice to say the 'involvement' of stakeholders in the research and decision making process is key for a trustworthy and effective governance. This is largely why the failure of the referendum hasn't blown back on the Labor party, as evidenced in the Dunkley by-election, with a minor 3 point swing to the libs and a Labor retention.
