Plants close to boundary - regulation?

Hi,

We had some gardening done at our rental property and the neighbours are now complaining they the gardener had planted some of the plants too close to the boundary (which is a brick veneer wall of the neighbour's bedroom that is right on the boundary) They are claiming they there had to be a 50cm clearance to avoid "damage to the wall and foundation due to increased dampness from watering those plants"
Sounds all a bit ridiculous to me but I wanted to check whether there is any regulation around this in Victoria.
Any advice is appreciated!
Regards, Christian

Do you have a photo?
I think it sounds abit ridiculous as well. As a home owner, your obligation is to stop water from entering neighbouring properties. It wouldn't flood their area I'm sure?

I thought that only non habitable rooms can have boundary walls. I would ask for the legislation that stipulates boundary set back for plants. I think it is quite normal to have plants planted next to the fences.

Read up on boundary walls and I think you will find that they should not be walls for habitable rooms.

The neigbiur's house was built about 2005/06, we brought the property in 2011.

Here are some pictures of the plants in question.
