The tall bamboo blocking views would be a breach of our rule (by-law): “A unit owner must not use the unit, or permit it to be used, in a way that causes, or will cause, or may grow to cause, a nuisance or substantial annoyance to an owner, occupier or user of another unit.”
That is slightly tweaked from the ACT default rule but I expect other states have something very similar. It seems you could use this to go to the tribunal for an order to clean up. In the ACT ignoring a breach notice is itself an offence, perhaps elsewhere also. Issuing a breach notice requires following a particular process and inclusion of particular details set out in the Act.
