Bala St. Sebas. was just on the boundary of my stomping ground when I was a kid so I can sort of recall what it was like (just), it was the 1950s after all.
From Albert St to Yarrowee St I recall a few houses on both sides of the Street. After Yarrowee St the South side of Bala St was a paddock, There may have been one house on the corner of Yarrowee St. the north side I have only a hazy recollection of, maybe a mullock heap. I remember the paddock because we went looking for Yuilles Wool shed and house, we never found the wool shed but did find evidence of the house. Yuille was one of the early settlers before the gold rush so I guess even then I was a bit of a history nut. Oh and Lake Wendouree was Yuilles Swamp.
Very vague sorry but it was half a century ago. good luck with your hunting.
