Detergent smell from laundry on balconies

I am having a problem with people hanging  out their washing at all times  of the  day and night (sometimes 11pm) in their balconies and there are strong laundry smells coming into my whole flat  and into my bedroom at all times of the day and  night from my next door neighbour to tenants living in the opposite and next  door block of units.

I have complained via emails and telephone to the different building managements and strata managements of our building and also the building across the road from us and the next door building but they will not take any action and my concern is the constant daily 24 hour exposure to the chemicals in the detergents and its health effects in my own home.

Rang council and complained but they said  it is not in  their jurisdiction to deal with this issue. What can I do?
