Multiplex began as a small construction company in Perth, established by John C Roberts AO in 1962. Multiplex quickly gained a reputation for delivering major landmarks on time and on budget, before expanding into the leading international contractor, Brookfield Multiplex, as it is known today. Notable projects built by Multiplex include 108 St Georges Terrace, Perth (formally Bankwest Tower), Southern Cross Towers in Melbourne, Chifley Tower in Sydney, Riparian Tower in Brisbane, Emirates Tower in Dubai, and major projects in the UK. John Roberts became an Officer in the General Division of the Order of Australia in 1988 for his contribution to the construction and horse racing industries.
