The Australian Catholic University will build a new campus in Blacktown after the council offered part of a new high-rise building, sports facilities and local business partnerships to any institution that would commit to opening a full campus in the next four years in western Sydney.

The university will initially open a "pop up" campus for 1000 students within a Blacktown City Council-owned office block in the Blacktown CBD, with some diploma and certificate programs expected to commence in 2020 and undergraduate and postgraduate programs to be offered from 2021.

ACU is also planning to build two new campus buildings in partnership with the council, that will house up to 3000 students in the next five years.

The council said further sites are available to eventually expand the campus to 30,000 students.
