Here is a rare advert by Meriton Apartments from the 1980's that I have scanned. It is for a three level walk up apartment development at Blacktown simply known as 26 Mantakas Street. The development comprised of six buildings. The one featured in this advertisement from 1987 is for the Briarwood building.

I managed to look up to see how much the apartments sell for today. They have sold for up to $330 000 in recent times.
