Aboriginals usually consider their old people or lawmen and women as 'Bosses'. This is usually with endearment and respect. Non-Aboriginal experts are often considered with suspicion and with a sense of have 'they no shame' to talk about us like that. This is different to Aboriginal people asking non-Aboriginal people to speak on their behalf, although this can be, and often is, a source of conflict within Aboriginal society itself. There are other non-Aboriginal people who this would not apply to.
Respect has to be earned and won from Aboriginal people.
Usually another Aboriginal person will have to present the credentials of the non-Aboriginal person, but there is no guarantee they will always be accepted. Aboriginal people in this situation can sometimes feel compromised and distressed themselves, not only if rebuffed by Aboriginal people, but also if it is something that is required of them in relation to the job they have to carry out. It is often offensive to Aboriginal people when some non-Aboriginals presume they have a right to be in a meeting that is about Aboriginal matters. It certainly strains the relationship between the Aboriginal Bosses themselves. It is an offence or presumption which is interpreted as lack of respect for the culture and the confidential nature of the Law.
