Moving in/out of unit

Background: Renting 2 bed flat in Sydney NSW in an all residential building of 25 units. Have been renting the unit for past 2.5 years, initially on a 12 month contract and then have been rolling since then. Question: I was recently advised that new by-laws have been implemented dictating arrangements for moving in/out of the units. In short, the new by-law requires that you must utilise a professional removals specialist to complete the task for you, and further still it goes as far as to tell you which company you must use to carry out the removals activity. Is this really enforcable? Q1 – Can they enforce that you must use a professional removals company? Q2 – Can they limit your choice to use only their nominated removal company? Q3 – Can additional by-laws apply to me given I am an existing tennant? Q4 – Does the fact that I am on a rolling arrangement outside of the initial lease agreement waive any of my requirements to comply? Many thanks in advance for any feedback. – See more at: http://www.flatchat.com.au/forum/how-to-post-to-the-forum/by-laws-governing-moving-inout-of-property/#p12789
