It's now believed the varroa mite could have been present in the Hunter for years, following an enquiry into the parasite's origin in the region.
Surveillance conducted after the mite's discovery at the Port of Newcastle, indicates there were high numbers of mites in hives up to 10 kilometres away from the detection point.
Australian Honey Bee Industry Council (AHIC) CEO Daniel La Feuvre appeared before a senate inquiry into the adequacy of Australia's biosecurity measures last week, and said the parasite "probably originated away from the port".
Mr La Feuvre said the AHIC is still unsure where the mite came from, but noted a number of high-risk local pathways, including the airport, RAAF base, and industrial area.
Port of Newcastle dropped-off Plant Health Australia's (PHA) most recent list of high-risks ports, because it is a bulk handling port, not a container port.
However, in response to the outbreak, the AHIC made a number of recommendations on improving port biosecurity measures across the board.
