MACA Infrastructure commenced operations in 2009.

It has rapidly built a reputation for delivery of quality projects and maintenance contracts that are delivered by one of the highest skilled workforces in the industry. The ownership structure of MACA Services (formerly Services South East) is now 100% owned by MACA Limited.

MACA Infrastructure – formerly Services South East Pty Ltd (SSE) has been a successful participant in the infrastructure maintenance industry for over thirty years. At its foundation is the high level expertise and skill of the former RPC Roads business - owned and operated by Robert Portbury. RPC Roads was a highly successful and respected participant in the Infrastructure Maintenance and Construction sector up to the time of its sale to Downer EDI Works in 2003.

RPC Roads was the first private contractor to be awarded routine infrastructure maintenance contracts in both Victoria and South Australia. RPC had been a significant participant in VicRoads and DTEI SA contracts from 1995, and continues to be so through Downer EDI Works. RPC Roads maintained over 27,000km of major roads and highways over the two states.
