Asthma On A Plane

Technically you are only supposed to carry what you need for the duration of the journey with you on board a plane. I had no trouble carrying a few months worth of insulin and asthma inhalers with me in my carry on to New Zealand a couple of years ago though. Biggest issue is going to be finding the space for all your stuff in your carry on.

But, if your carrying so much stuff that it looks like you are trying to import the drugs then customs could be liable to stop you on arrival. If you are travelling over long term then you are better off to register with the local GP and get local prescriptions when you get there. You may even find that the condition of your asthma is different once you are over there, the severity of mine changes quite a bit depending on what part of the UK or Ireland I happen to be living in at the time. You may find that Oz atmosphere suits you better, or it might not and you need a different inhaler.
