I am a little confused by the wording of your post, but assuming that the trees are on your Strata Plan, it matters not whether they’re on Common Property or on any part of a Lot, all growth above the strata limit (vertical) is the responsibility of the Owners Corporation.Individual Lot Owners do have a responsibility to keep the height of any and all trees / shrubs on their Lot below the strata limit, so provided they’ve been planted since the Registration of the Plan as opposed to being existing trees that were left in place during the Development, you may be able to obtain a contribution towards trimming costs from the Lot Owners concerned – but that would of course be voluntary.
Whale, the way I read Jeff.f’s post is that the trees with falling (or potentially falling) branches are in adjoining properties to the strata development.
If it were me I would approach the local council tree person and submit that the trees are dangerous and people using their courtyards could be injured or killed by falling branches.
The council should send out their tree inspector and if he or she agrees that the trees are dangerous, then a letter should be sent to the owner/s of the trees asking them to either trim them or cut them down.
I know because when I had a house and garden one of my trees was overhanging a neighbours garden and I had to lop several very large branches. An arborist charged me almost $2,000 to do the job in suburban Sydney.
Hopefully your neighbours will pay the cost for you and the other strata owners.
All the best.
