BBQ smoking…

My downstairs neighbor has a BBQ mounted on the external wall/ground floor below our living room windows. If they are using their BBQ and our windows are open the smoke sets off our smoke alarm. At such time if we happen to be home we need to close 2 windows, fan smoke away to stop the alarm. Plus, the smoke has soiled the walls above the windows which required (getting up on a ladder) sugar soaping to clean yearly.

When discussed at the recent Strata Meeting of owners nothing was resolved when suggesting the BBQ be moved away from the building- across their garden or a hood installed above BBQ to deflect smoke coming into our apartment upstairs. What leg do I have to stand on to demand a solution to prevent smoke coming into our apartment? Is their any strata legislation to back my demands when pressing this issue to the Strata committee?

Thanks for your input. CAJ
