Google it, naveed. But, as I recall, there used to be a very simple, blanket policy, whereby people of African and Asian skin-colour were barred from immigration to Oz.
Further on you can see my explanation, i.e. that colour prejudice is, of course, a result of the Fall, and neither based on reason nor unique to 'white' people. However, measures to avoid it, to forfend against the indigenous(?!) whites losing their sense of identity, by managing the numbers of 'coloured' incomers, need not be irrational or malign. Grace builds upon nature. We don't acquire virtues by making single decisions, do we ? Some features of our human nature, such as this need to preserve our sense of identity in our own country, fall into this category. Blind, mindless hatred must be controlled by the individual, but some latitude for human nature, such as it is now, must be taken into account.
The caste system in India is institutionalised racism of an extarordinarily virulent order, although technically I believe it is now banned. In fact, the PM (or President) is a Dalit. But a majority of Dalits are still persecuted with impunity by people of higher castes.
I believe the Australian Aborigines, having lived for millennia on the margins of existence, are natural mystics. The reason why there has been a false impression that Europeans have a superior intelligence is that Judaeo-Christianity enabled them to pursue empirical science in a purposeful way. According to Genesis, God made the world good ; other religions in varying degrees discounted the material realm as illusory, and an obstacle to spiritual growth. Also, the monotheistic religions, believing in a divine law-maker, looked to see such purposeful regularities in nature ; and of course, were not disappointed. The physical world does indeed invite rational analysis.
Unfortunately, with loony-toons Darwin's theory, which, by the way is not even scientific, preoccupation with the material world and the perquisites of material affluence it has provided, has meant that the spiritual intelligence, wisdom, including common-sense, has been increasingly marginalised, in favour of the insanely-destructive idiocy of corporate atheism, whose chiefs do not want their businesses or their personal lives to be subjected to moral constraints. Science is revealing every day the profound and wholesale idiocy of atheism, too vast and profound to even touch upon here, though you can see it yourself.
As a result, today, intellectuals of the races, which seem to have been 'late developers', such as the Indians and the Chinese, have turned out to have brilliant intellects, at least on a par with the best of the West. The Chinese invented printing several centuries before Western Christendom, but were not prompted by their religions to further pursue investigation of the material world. Another interesting non-white people with an intriguingly technically-advanced civilisation which glowed very brightly but briefly were the Mayans :
'The Maya Empire, centered in the tropical lowlands of what is now Guatemala, reached the peak of its power and influence around the sixth century A.D. The Maya excelled at agriculture, pottery, hieroglyph writing, calendar-making and mathematics, and left behind an astonishing amount of impressive architecture and symbolic artwork. Most of the great stone cities of the Maya were abandoned by A.D. 900, however, and since the 19th century scholars have debated what might have caused this dramatic decline.'

(I believe all I am writing here can be found, at least, in principle, in one of Aldous Huxley's books of essays).
The tendency towards a high level of worldy intelligence of the Jewish people, I suspect has arisen as a result of their keeping a written record of their history dating back at least a thousand years before any other. In early biblical times, as for example in the days of King David, they were a simple, pastoral people - while the Egyptians and Philistines were the advanced civilisations. Kind of ironical how the meaning of the term, 'philistine' has developed. The brain seems to act as a reducing-valve, straining out a potential Beatific Vision, to enable us to survive in time. Or we'd just 'fester' in a trance ! Lotus eaters.
However, for me, the most fascinating peoples are the black peoples of sub-Saharan Africa. They seem to have been greatly blessed by God physically, yet their gestation as competitors in terms of worldy intelligence seems to have been slower. In recent centuries, they have been held back by the plundering white people. The Chinese and Russians seem to have been showing a more Christian concern(!) to give something back in terms of building infrastructure, etc, although it has doubtless been in part, self-serving. Still ! It is exemplary, isn't it.
However, I think that they will prove to be the most egregiously worldly-wise brain-boxes in the course of time, since they characteristically have a high level of emotional intelligence, and worldly intelligence can only be a degradation of it, however providentially designed for our survival in time.
A key-factor, I suspect, also in this respect is that if ever a country/continent would engender a 'manana', come day-go-day-roll-on-Sunday attitude to life, it would be the countries of sub-Saharan Africa. There's that saying : 'See Africa and die', isn't there ? On the other hand, in the colder, Nordic countries, physical ingenuity would be at a premium, just to keep warm and eat.
The evidence today in the US, judging from TV programmes, is that the African American community does not lack for professionals at the highest levels, despite the obstacles placed in their path by a hostile social environment.
