I'm strongly leaning towards a Yes vote as I don't see any harm in the proposal. I think arguments around it being divisive, lacking in detail or constitutionally dangerous don't hold any real weight.
That said, I don't think the Voice will make any tangible difference towards closing the gap, improving Aboriginal welfare or creating true reconciliation. I would be shocked if anything has changed in 10 years. If you look back across the last 50 years, there have been several bodies like the Voice which have all been failures (NAC, NACC and ATSIC).
Unfortunately, the debate on Aboriginal issues is extremely limited and unless you subscribe to the view that Aboriginal issues are all the fault of the evil white man, then you are a racist. The reality is, whilst Australia has historically treated Indigenous Australians poorly (it really is a blight on the nation's history), Indigenous culture has many negative elements (like any other culture around the world) which are actively holding them back. Unfortunately, the culture is very patriarchal and their norms around ownership of property are just completely at odds with modern society. Add in their somewhat justified reluctance to interact with White Institutions and you have a culture stuck in the past with no way of improving or moving forward. As much as I dislike his politics, Tony Abbott made an excellent point that "If Indigenous Australians want to achieve Australian outcomes, they must embrace Australian standards". Unfortunately, if any one in or around government were to say this they would be branded a racist and probably shot at dawn for their transgressions.
To spout some more cliches, "You cant change what you don't acknowledge" and "The definition of insanity is doing the same thing over and expecting a different result". I think the Voice will just give a bigger platform for the same tired solutions that haven't been working for the last 30 years.
