In comparison, the Bay of Plenty crops - New Zealand's other major avocado export region - have been disappointing, partly due to the trees' natural cycles, which see crops heavier some years than others.
Mr Carroll would not speculate whether the recent heavy flooding in Queensland would mean better prices for New Zealand, saying it was too early to tell.
He said because of the harvesting time differences between New Zealand (September to January) and Australia (May to July) any impact would not be felt until late in the year.
Bundaberg, one of Australia's biggest avocado areas, was hit by the floods, but it is not the only area to grow avocado.
Mr Carroll said unless trees were uprooted or significantly damaged, the trees would potentially have time to recover before harvesting began in May, although crops could be lighter than the predicted moderate season before the floods.
