You are right that it is an issue that is talked about and it was discussed in the lead up to the the 2016 election. However, since the election there has been very little attention paid to climate change and there is some evidence that Australia is on-track to be in violation of the Paris Agreement[1].

Australia chose to elect a party with policies that target greenhouse gas emissions the least, 26-28% 2005 levels by 2030, where the next most popular party has target of 45% 2005 levels by 2030.

The former Labor government introduced a tax on carbon emissions[2] and a mining resource rent tax[3] in 2012. These taxes were later repealed in 2014 by our current Liberal/National government. Since the repeal, our emissions have been steadily increasing[4].

Talk is cheap and when push comes to shove on climate change, the majority of Australian's give into the scaremongering of conservative politics.
