Theres a lot of research going into carbon sequestration through soil and plant technologies - basically accelerating what would happen naturally by a few orders of magnitude.
Rapidly filling artifical peat bogs (through things like algae/weeds that are genetically modified to absorb more CO2) would allow for semi-permanent carbon capture as long as no one digs it up again. Similar projects with seaweed are under research as well.
Personally I think anything to do with carbon capture is a bandaid at best, and failing massive global cooperation and societal change, we're going to end up needing to geoengineer our way out of the problem. Things that block or impede solar heat absorption to cool the planet - atmospheric aerosols, artificial cloud generation, solar shades out in a lagrange point, basically manipulating conditions to influence how much energy is going into the system. There's a nonzero chance we fuck it all up but as we hurtle through temperature records and tipping points, the idea of net zero emissions actually having an impact in our lifetimes seems more and more unlikely. There's too much inertia in the system.
The context is important here - Australia had a continuous indigenous population for over 60,000 years before white settlement. White Australia never had an agreement with indigenous peoples at large, and through relentless expansion of colonies, spreading diseases like smallpox, introducing alcohol and drugs, forcibly abducting and schooling children, heavy incarceration and a slew of other typical British colonial shit ended up leaving them disenfranchised, alienated, and excluded. Indigenous Australians prior to colonisation had a deep affinity with the land and tended it like custodians, but because they didn't build towns or farm like Europeans, they were just swept aside without ever really being acknowledged or addressed.
The Voice was asked for as a product of the Uluru Statement of the Heart - not long, worth a read- https://ulurustatement.org/the-statement/view-the-statement/
It was really first and foremost about having an acknowledgement that maybe, just maybe, the settlers cocked things up and that it'd better to fix things together. It's not asking for anything "more" or extra, it's about correctly telling history and reframing our national dialogue to be coming from a place of partnership, instead of colonialism, so we could fix some of the very real issues modern Australians face as a result of hundreds of years of callous racism. It was a chance for white Australia and government to really listen and maybe find better ways of doing things.
But now instead we get to try to explain to our kids why 60% of the country don't think representation or inclusion matters while indigenous Australians will continue to struggle without a government that can listen to them.
