Yes! It can be done! Normally, to avoid fruit fly and caterpillar attack on large fruited tomatoes, it's best for Queenslanders to plant them in Autumn so as the soft, fragrant fruit ripens, it is in the cooler weather when there's less pest around.
In our Worongary garden, we put a fruit fly net over our tomato bed and I tell ya, I was eating a Franchi Red Pear tomato and slicing it like a Christmas ham on Christmas day! These tomatoes are growing in our Spring/Summer period
