Newly acquired plants if not managed carefully will experience transplant shock. The reason being they usually originated from a controlled environment like a nursery. When radically exposed to a new environment they will sometimes shed their leaves and fruits and even limbs. The key is to gradually ease them to their new home. First from a sheltered position for a week then increasing the amount of sunlight as time goes on until it is fully hardened but, never exposed it to high 30's and 40's temperature.
What you can do now is to prune all the limbs that are dying up to a healthy tissue and a couple of inches for good measure. Don't expose it the harsh Australian summer sun if you are living in Australia. Water it with a weak solution of seasol to assist in its recovery. Monitor the watering to just right, not too much nor too little. I usually use my finger to check the moisture level. The leaves are also a good indicator. It will show it needs a drink by exhibiting a very slight wilting. Monitor its progress over the next few days and weeks.
