Change of Strata Manager

Hi All, 

Need some direction, I am on owner of a lot in a duplex, we recently held an EGM and voted to change Strata Managers. It’s been approximately 8 weeks if not more since the EGM, the new Strata Manager are doing everything in their power but the old Strata Manager are not passing over the following items:- 

1. Owner ledgers
2. Bank statement for 1/7/13-30/4/14
3. Set of financial reports for the period of 01/07/12-30/6/13
4. Paid invoices

They have also stated that the other Owners have and are refusing to pass over these items as well:-

-Original Certificate of Title
-paid invoices
-Minute books

The other Owners have stated they do not have these items and are unsure why the previous strata manager would say such.

I need some direction as to what I should do especially in relation the the minute book and original certificate of title, the other Owners and I do not speak as we are in dispute so can’t discuss with them either. I have a current application at the NCAT. The other Owners also show no concern about these issues and I am worried about fraud. 

Thank you in advance.
