Noise from common property

Hi, 

I was hoping this forum could help me with a problem I'm having.

 I've been renting this apartment for about a year now and  recently the lifts in the building have been becoming very noisy, mainly because there not well maintained. Additionally they malfunction and just go between the floors with no one in them for hours on end sometimes.  

It's got to the point where I often can't sleep due to the insentient screeching noise, I was hooping someone could tell me about the strata corporations obligations here. The lifts still get you from one floor to the next (with a few random stops) but my apartment is no longer what I signed up for doe to the constant noise.

Thanks in advance.
