Residents of 51 units in a Sydney Olympic Park high rise remain barred from returning to their homes after they were deemed unsafe, and it appears unlikely they'll be declared safe any time soon.

Authorities originally feared the 38-storey building was at risk of collapse.

Emergency services were called to the site on Monday afternoon following reports residents had heard and seen cracking in a wall throughout the morning.

The 36-story high-rise building was evacuated over concerns over structural instability.
