David Marriner is a property developer and theatre owner, based in Melbourne, Australia.
His career began in the 1980s with property investments and developments, including the Cumberland Centre in the seaside town of Lorne.
[1] In 1986, he purchased the historic but languishing Princess Theatre in Spring Street, restoring and upgrading it to be suitable for the large scale musicals then gaining popularity overseas.
The theatre reopened on 9 December 1989 with the musical Les Misérables, followed by The Phantom of the Opera.
The latter project saw his development company build the Westin Hotel and apartments on half the old Square site, and restore and then manage the adjacent Regent Theatre, which had been abandoned for 20 years.
