one factor could be the royalty system in place for traditional owners, mining companies negotiate with the TOs , its a significant amount in some cases, I know of one NT community that is paid $17000 per man woman and child per month. Now that's how the figure is worked out, that sum then goes into a trust fund, and is distributed by the elders how they see fit. The same community has "lost $34million" one elder was sent to prison for roughly $500K of it, but the rest is unaccounted for. Its well documented, easy to google. Now the mining company is not going to be happy paying a mining tax and royalties are they? So if a mining tax was set at XXX% , then the government would then need to pay the royalties, not the company, because they are not going to pay both.

Yes there is fraud in indigenius communitees, and yes some of the perpitrators are indigenous, the majority are not. The majority are the same scum you see insinuating themselves into NDIS, aged care, childcare, strata management, home insulation, home solar & batteries, school halls, defence (and government in general) infrastructure, facilities, estate and various non operational support contracts.
We have a layer of rent seeking excrement, many of whom become millionaires, some billionaires, who leach off money intended for others. As a nation we tend to kick the person who the money was intended for, but who didnt get it, whiles cellebrating, and sucking up to the thieving parisites who scam the system.
