The story lists the PM's position and offers the opposing parties reasons why they dislike his position and want everyone to help overturn it. Nothing about why the PM has taken that position in the first place. Is it that immigrants are more likely to infect unwitting Australians? Or maybe that the costs of care exceed any likely benefit that is likely to accrue from their coming to the land of Oz. Or no more likely to infect, no more costly against the Aussie government supported health care system (ROFLOL) but simply more people possible to infect Austrailian citizens, and more bodies on the Aussie medical dole. This story does not even admit to any possible reason for not wanting more expensive-to-treat HIV carriers in the Land of OZ.
