upcoming works not disclosed prior to settlement

Hi people

I purchased a unit this year and two months after I attended the first agm I was told a special levy of 12000 was required to fix the balconies.

This issue and how major it is was first disclosed to owners 6 months before. I fact they had a report done that said they were so unsafe they shouldnt even be used. They discussed financing and even had an egm one month before settlement to further discuss it.

The previous owner lied in his disclosure statememt by saying they were looking at replacing some decking on top floor units. In fact he was given a report of the issue and a break down of cost to fix it. And the situation is a lot worse the replacing a couple of boards. My settlement agent said she did section 43 enquiries with strata and nothing was mentioned about this. 

Would anyone have any advice here? Everyone in the process is just passing the buck. Saying another party should of disclosed this.  But who?

Thanks
