For decades, building a high-speed rail network in Australia has been derided as a financially flawed fantasy, even as Sydney¡¯s population strains at the seams and housing prices soar. The affordability crisis is now spurring Australian Prime Minister Anthony Albanese¡¯s government to bet on a 94 billion-Australian-dollar ($66 billion) fix.
