If you look at the history of Indigenous policy you'll see that many versions of advisory bodies have been legislated only to eventually be removed. Plus the symbolic value of constitutional recognition can't be understated. A tokenistic gesture, sure, but Australia is still the last settler colonial nation in the global north to recognise their First Peoples. For the sake of just the basic values of a modern nation we should at the very least recognise the people who were here first in our constitution.

The constitution has special legal status in Australia. Parliament cannot alter it the way they can normal laws. The constitution can only be changed by a referendum - which is vote by the whole nation. What parliament is allowed to do (not Albo individually, but by majority vote in parliament), is make laws under the constitution. So yes, parliament could pass a law that creates a voice. But the next government could then pass a law that cancels the voice. And so on. The idea of putting in the constitution was so that it would have more staying power. If it was in the constitution it could still be removed, but only by another referendum, because as per point A, constitution can only be changed by a referendum.

Well, that's democracy.

Regardless of your thoughts on this individual matter, I'm glad the results are upheld despite what I think should happen.

The real issue is why the Australian people voted the way they did. Disappointing for many.

If he truly believed it was a good thing he should have just legislated it to start off with. That way you have the benefits of such a body sooner, and if people can see something in action and actually working to close the gap they would be more inclined to allow it into the Constitution in a later referendum (and even if the later referendum fails you still have both the body and the work they have done).

Edit: To be clearer, it is possible to both legislate a voice and have a referendum on it while a party is in government, particularly since it is rare for a government to only get a single term.

A couple of things. First of all, the advisory body itself was only part of what was requested (remember that the request itself came from Indigenous Australians, not politicians). Constitutional recognition and an enshrined Voice was the request (along with treaty and truth telling), and a pretty simple one at that. It would have been condescending if the government had rejected that request and instead proposed to legislate only the Voice. This entire process was about listening to Indigenous Australians, not about government ignoring them and acting in its own best interests. This is a big part of the reason why the referendum went ahead despite poor polling.

Secondly, the Voice advisory body was a very safe, conservative-friendly proposal designed to get some movement on the issues of reconciliation and Indigenous sovereignty. It is not necessarily representative of what Indigenous Australians would actually want in a perfect world. So the argument that it should have just been legislated because Indigenous Australians should get whatever they want/deserve is flawed, because if we were to take that approach then alternative models like devolved self-governance should have been on the table too. They weren't, because realistically Indigenous Australians make up just 3% of the population and are forced to rely on the goodwill and support of the other 97% in these matters.

from a political point of view, it had to be a vote because it was an election promise by the albanese government, simple as that. if they didnt do a vote it would have been a broken commitment

Didn’t like the outcome hey. Fair enough.

Democracy in action. The constitution can’t change without the vote and the country voted. If he didn’t act accordingly it would be political suicide if he even made it come next election.
