All a Voice body would do is formalise the Indigenous lobbying industry. To suggest that there isn't already Indigenous lobbying that provides input (i.e. its Voice) to the Government of the day is ridiculous.
The actual Voice body will just be the same Indigenous lobbyists who already provide the same advice to the Government of the day. Why would their advice change outcomes for Indigenous people in remote Australia, if it is just the same people providing the advice?
Why would individual Indigenous lobbyists neccessarily suddenly all agree on the same thing if they don't now?
Nobody suggested anything - so nothing is ridiculous.
Your questions seem to be common, along with the "there are no details".

6. Don’t Aboriginal and Torres Strait Islander people already have lots of ‘voices’ to government and parliament?
No. There is currently no representative body to provide, in a nationally coordinated way, the government and parliament with the views and experience of the Aboriginal and Torres Strait Islander people who will be affected by their decisions.
To the extent there are other Indigenous organisations working with government and parliament, the Voice will complement, not detract, from their work. For instance, peak service organisations working in areas such as health, education and law, offer important Indigenous specific services and advice to government in service delivery, they are not representative.
And while there may be more Aboriginal parliamentarians than ever – and this should be celebrated – these individuals do not primarily represent Aboriginal and Torres Strait Islander people. They are party members bound by party policy, or individual MPs, who represent the whole of their constituencies. Further, Indigenous representation in the parliament is not guaranteed – it will rise and fall depending on party selection, and election results.
Finally, while individual traditional owners might be able to negotiate land claims and native title rights with government, they do not have a nationally representative voice to speak to parliament and government in a coordinated way about the laws and policies that will apply to these negotiations. There is no one to make sure the rules of the game are fair.
Strengthening of Indigenous cultural expression and conservation and working with communities to set priorities and greater influence over decisions that affect them.
