For a number of reasons, including clarifying the role of institutes of technology, the Federal Minister for Education of the time (John Dawkins) created the unified national system, which compressed the former three-tier tertiary education system into a two-tier system. This required a number of amalgamations and mergers between smaller tertiary institutions, and the option for institutes of technology to become universities. As a result of these reforms, institutes of technology disappeared and were replaced by a collection of new universities. By the early 1990s, the two-tier tertiary education was in place in Australia – university education and Technical and Further Education (TAFE). By the early years of the new millennium, even TAFE colleges were permitted to offer degrees up to bachelor's level.
