The University of Technology Sydney will open Australia's first Indigenous residential college to encourage more Aboriginal and Torres Strait Islander students into tertiary education.

Architects will consult Indigenous designers before beginning the construction of a $100 million building at a site near the Ultimo university, which is expected to open its doors within four years.

UTS aims to remove the barriers that have been hindering Aboriginal and Torres Strait Islanders' access to university education, such as cost and cultural isolation.
