No sure anyone should be happy as there seems to be a big job ahead healing and uniting a very divided country.
Hard road ahead.
The positive out of all this is that class politics is back, and its intrinsically tied to immigration and free trade agreements.
Go back to Australia's history when we had a very strong Communist party, and you'd see that immigration was always a hot topic, as was jobs and protecting those jobs from cheap imports. We have a situation in Australia where both major parties are in favour of epic levels of migration to the tune of 250,000 or so per year mostly from China and India, and use 10,000 odd refugees as a way to deflect attention away from that.
There's nothing wrong with having these discussions, but the party system avoids it because large corporates are heavily invested in destroying union membership, lowering wages and gaining constant sources of cheap labour. FTA hurt even more than immigration, and again only serve the absolute wealthiest people.
This is a win for economic regulation and an acknowledgement that the free market has not been working for the average person.
