http://dcleaks.com/ have revealed that billionaire, George Soros, has used billions of dollars to try to bring about open borders by funding NGOs all over the world to harass people who do not want mass immigration. Tactics taught are to equate all immigrants with refugees and to accuse people who want control over immigration numbers of racism.
Hackers have revealed that Australia's GetUp, like its U.S. counterparts, MoveOn and Avaaz, have massive financial support from Soros and that their agendas conform to those of Soros. Labor Leader Bill Shorten is linked to Soros-funded activities as is Greens Sarah Hanson-Young.
Bill Shorten, Australia's opposition leader and GetUp.
"GetUp! was established by activists Jeremy Heimans and David Madden with funding from Soros. The Labor-affiliated Construction Forestry Mining Energy Union donated $1.1 million to the group. Bill Shorten and John Hewson are former board members. A major funder listed on its 2014-15 Australian Electoral Commission expenditure return is Avaaz, the US GetUp! affiliate that has received copious amounts of funding from Soros networks."
Now we have some idea why Bill Shorten refuses to reduce immigration. How many politicians have been influenced this way by Soros's money - either as recipients of awards, and positions or through funding? (We also know that every recent prime minister and opposition leader has become a member of the Australian Multicultural Foundation, which seems to have similar mass immigration values and leadership program links but no apparent affiliation with Soros. The Scanlon Foundation has mass immigration and opinion shaping agendas but no apparent links.)
Soros's money has influenced 'Leadership programs' in many areas, university grants and journalism in Australia. Google "Open Society Foundations".  Consider the impact of this on the formation of Australian politicians, researchers, academics, journalists, presenters, teachers, 'ethnic leaders' etc. Emily's list, for women aspiring to get ahead in politics, is financed by Soros, so we know now why the women who get ahead in Australian Labor have nothing serious to say about population or the natural environment.
The Australian Greens
Greens Leader Sarah Hanson Young was named a 'World economic forum young global leader' for 2016. George Soros is the chairman of that forum.  The Greens have, over the past decade or so, changed from a conservation platform to an open borders one employing the tactics of unfairly stigmatising people as racist and xenophobic when they call for limits on economic immigration in order to protect our natural environment. Who or what changed so many of them?
"They attack democratic states by advocating a porous border policy, reframing illegal immigrants as refugees and degrading critics of totalitarian tendencies such as Islamism in orchestrated campaigns of PC censorship. Documents uncovered by Soros leaks reveal a pattern of funding for programs that prosecute porous borders, mass immigration into the West nations from Islamist regions, and overt campaigns against dissenters. OSF has provided several million to the Centre for American Progress, whose programs include the explicit targeting of freethinkers critical of Islamism. A recent program grant described a strategy to target six critics of Islamism and the “right-wing media” in an “audit of Islamophobic activities”." 
Need to list Australian organisations and people linked to Opens Societies Foundations
There is a list available of United States organisations funded by Soros, but none available of Australian ones. Nonetheless, the U.S. list is very informative of the kinds of organisations that Soros has used to undermine national sovereignty.
'Independent' on line newspaper,New Matilda, praises South Africa's Mail and Guardian, calling for more papers like these and noting approvingly that they are backed by the Open Foundations Society.
"The twist, with South Africa’s Mail and Guardian, is revealed inside its front cover: its investigative reporting is supported by the Open Society Institute. To justify that, of course, it has to be clear that journalism is worth having, and capable of fulfilling a socially useful function as a civic tool in democracy." https://newmatilda.com/2012/06/19/journalism-we-really-need/
 Jennifer Oriel, "Dumped files show influence of George Soros on Western politics, The Australian, August 22, 2016, http://www.theaustralian.com.au/opinion/dumped-files-show-influence-of-george-soros-on-western-politics/news-story/937a225e62420ea3807bd8308b0dad83
 For example: https://blogs.adelaide.edu.au/rb-bulletin/2015/05/26/open-society-foundations-open-society-fellowship-20152016/, http://www.uq.edu.au/uqadvantage/robert-walter, http://findanexpert.unimelb.edu.au/display/person460793#tab-research, International journalism grants: https://www.icij.org/about; Leadership programs: https://cpd.org.au/author/phil-lynch/ and Open Society Foundations: https://www.opensocietyfoundations.org/press-releases/open-society-foundations-launch-worldwide-fund-support-nonprofits-navigating; and so on - just keep googling. So many of our academics, researchers, politicians, journalists, have received funding from The Open Society Foundations (George Soros) and to get this funding they had to conform to its values and tactics.
