Owner willing to pay for removal of problem tree

One of our small trees on the common property has damaged the storm water pipes and the tree needs to be removed. It’s not very large and doesnt need council approval as we have checked. The issue was raised at the last AGM and the EC are ok with removal of this tree but don’t want to spend the money at this time.

As it is in front of my unit, I said that I would be happy to obtain quotes and if it’s not too expensive, pay for the cost myself as I don’t want it to turn into a bigger problem. But the SM said leave it until there IS a bigger problem. But we have already had one problem that required the plumbers to use an electric eel to partially unblock the pipe which was my Downpipe. (Water was overflowing from the Downpipe next to my window). We have the funds to do this if the cost isn’t too large but as usual the concept of looking after our common property,  if it means spending anything, is the biggest problem. My question is – is there any potential problem if I pay for it myself. Thanks.
