My experience is similar to Gone tropo's. It's pretty common to have mature fruits, small fruits and flowers on the tree at the same time. If it is dry, they will drop fruit. I have found that chucking a hose under the tree for 5-10 min 1-2 times per week does the trick. In the case of heavy rain, you will lose some fruit due to splitting. Flying foxes love them, bagging does help. Lastly, the fruit is very sensitive. If dropped, the fruit will develop a terrible taste after a couple of hours so I recommend eating straight away. If handled well, the fruit is good to sit on a bench top for a few days without any issues. I don't recommend storing in the fridge as they will go brown.
