Large part of it is from air travel greenhart,I have provided in the past figures proving beyond any doubt that Australia has by far more Co2 from jet engines and coal is a very distant source.
We need more Co2 and we are fortunate that jet engines while more efficient produce millions and millions of tonnes of Co2.

I was interesting when I was researching this matter how difficult it was to source up to date data..but there are always methods.
