Mirvac started off as a residential property developer and over time expanded into property investment, funds management, and commercial property development. Investment is the major earnings driver, generating about two thirds of group earnings. The investment portfolio, by book value, is made up of 60% office, 20% retail, 15% industrial and the rest is build-to-rent and land lease assets. Longer-term, Mirvac aims to increase exposure to the industrial and living sectors and own fewer offices and retail centers. Development income is volatile and was around a third of fiscal 2024 group earnings. Besides developing apartments and houses, which Mirvac is best known for, it is also involved in commercial and mixed-use precinct developments.
