chances of that melt being english are very slim.
if australia wants to go down the zimbabwe route then thats upto them i suppose, like you said catering to minority groups, as i pointed out when in aus. the attraction for most of the immigrants in the 60's from greece, italy etc was the links with the uk, they told me they saw it as england with sun, then they no longer want to be part of the commonwealth family and become a republic, in terms of problems with migrants i see it going the same way here as well, with some groups already wanting their home rules to be allowed here with disregard for the uk laws.
