Unless you're buying food, electricity, superannuation, health insurance, a mortgage, mobile phone service, Internet service, streaming TV, news media, cars or housing.
For some reason the ACCC can't find evidence of anticompetitive behaviour in those industries.
While they are not as good as they could be, there have been many cases awarded against Telcos, ISP's, Banks and Energy providers. It can only operate within our laws though so I do agree they could be given more powers, but only a decent government can do that, sadly which we havent had for a long time now.
