We have intercity trains in australia, barely anyone lives in the outback. Our largest barrier to public transport use is poor last mile services, our train networks are actually fairly extensive.

Only problem is interstate travel and investment. QLD, Perth-area and Tasmania all (primarily) use narrow gauge, NT, NSW, SA and the rest of WA use standard gauge, and Victoria uses broad gauge. 

It’s not impossible, but our current system is geared towards intrastate, freight and tourism. The only high-speed rail we have is the Brisbane-Cairns lines and they don’t even run at that speed commercially. It would take a lot of work/money to make the current system a viable alternative for passengers.
