They're pretty much all on the same team. I think that's mostly as it appears. They're all just fighting over the PM's chair for personal gain. Does not matter which of the two party governs, though one side fucks over the population a lot faster than the other lately.
Sadly, only anons AFAIK. There are some outlier current/former politicians deemed "crazy" who are either patriots or controlled opposition.
The global agenda has been nicely compartmentalized between "progressive" and "conservative" initiatives so voters can switch governments as much as they like and end up in the same place at the end. Basically gotta wait until the beast's back is broken at the source, which is not in Aus.
