From two founders into the leading player on the markert
Bridging the west and the east
Black Diamondz Group was founded in 2009 by Monika Tu and Jad Khattar to set a new benchmark in Australia's luxury real estate landscape. Monika, a renowned Chinese-Australian executive, transformed the way global buyers, especially from Asia, access Sydney's most exclusive homes. Her expertise, industry accolades, and unmatched cultural insight make her Sydney's leading authority on luxury property and the bridge between East and West.
Jad Khattar, with deep roots in international business and construction, brought complementary vision and expertise. Together, Monika and Jad built Black Diamondz on three core values: exclusivity—offering rare access to off-market properties; integrity—ensuring absolute trust and discretion; and cultural connectivity—delivering seamless, bilingual service to a discerning international clientele.
Beyond real estate, Black Diamondz delivers tailored lifestyle solutions, education placements, and innovative East-West communications. The Group's commitment to excellence and community leadership has earned it a reputation for redefining the standards of luxury, trust, and global connection in Australian property.
