Why has she taken so long to get moving on this? Still, beggars can’t be choosers. Pauline Hanson, whom I have not heard much from lately, has called for Australians to be given a vote on the immigration intake, by moving a Notice of Motion  for a plebiscite at the next general election on Australia’s immigration levels, the Plebiscite (Future Migration Level) Bill 2018:

The Notice says:

“Did you know that about 60% of Australia's population growth is driven by our high migration numbers?
Did you know the Government has projected that over the next 4 years they will bring in around 1,000,000 extra migrants?
If you were given the option of voting to end mass migration into Australia what would your answer be?”

     It will be interesting to see how this goes, because the bill is up against the big Australia economic rationalists, who want to make the capitalists richer from immigration, and then there are the politically correct Leftoids, who had adopted immigration as a new religion. Nevertheless, in all of these articles, and especially this one on voting, remember the Immigration Write on campaign which will allow you to express your righteous anger about this:
