Coolbellup is a suburb in Perth, Western Australia, located 15 kilometres (9.3 mi) south of the central business district within the local government area of the City of Cockburn.

Coolbellup was originally the eastern portion of George Robb's Cockburn Sound Location 10.

Early landholders in the area were G. Jarvis, Joseph Meller and the Dixon family.

A vineyard also operated in the area and remained in production until it was cleared for housing in the late 1970s for what is now known as the suburb of North Lake.

During the 1960s the area's population grew quickly with families moving into modern brick houses on large blocks provided at low cost loans by the state government.

[5][6] By the late 1980s Coolbellup's post-war population boom was over and gradually the demographics changed from young families with children to older residents.

These changes, together with the suburb's location and Perth real estate trends, have resulted in a significant increase in property values in the area.

The houses in the area are typified as 1960s 3-bedroom-1-bathroom brick and tile cottages with solid timber floors on 700 m2 (0.17-acre) blocks.

These houses are once again proving popular with younger couples and families seeking character homes within 15 kilometres (9.3 mi) of the CBD.
