Great to hear that Baynanno1, and confirmed by contacts in Oz that the rain is at times torrential and should hopefully reduce the pollution. Sadly it will take a long time for Oz to recover, and wildlife has been decimated.
I also note comment from Jelayne, however, we also have our own masks having recently been in Rajasthan where the smoke pollution was dense, but on that occasion many from other parts of the world were not aware of the problem and suffered badly until they could purchase some. Chances are that there will be passengers onboard unaware that the Journey could be impacted
