The main reason is the increase in the population, caused by the immigration policy. New citizens, new PRs and more FTs is overloading the transport system. Then everyone who uses the public transport has to pay higher fares in order they can provide quality service. Before when we had a population of about 4 million, things were not so bad, we were not so squeezed and fares more affordable.
These bastards start increasing the population and we kenna screwed. WTF. Furthermore, everything else also rise in tandem, and we again are screwed even harder. Even our children are affected as there are less places in Primary schools of our choice and we also need to send our kids overseas to study because the local U has no place for them.
