Three and a half years after the first varroa detection at the Port of Newcastle in June 2022, and almost exactly two years since the National Management Group formally accepted that eradication wasn’t technically feasible, the Australian beekeeping industry is in a very different place than anyone wanted to be. Varroa destructor is now confirmed across most of New South Wales, southern Queensland, eastern Victoria, and was detected in South Australia in late 2025. The question isn’t whether it spreads — it’s how the industry adapts to becoming a managed-mite jurisdiction like every other significant honey-producing country.

The current spread picture

DAFF’s National Varroa Mite Management Program publishes a public dashboard, updated monthly, showing detection clusters and surveillance results. As of the late April update, there have been over 4,800 confirmed infested premises since the eradication decision was reversed. The actual prevalence is certainly higher — DAFF officials have been reasonably candid that surveillance gaps in remote areas mean detection lags reality by 6–12 months in some regions.

Western Australia remains the only state without confirmed varroa, and the WA government has invested heavily in maintaining that status. Movement controls at the Eucla checkpoint have been upgraded, and DPIRD’s surveillance program is detecting at densities below 0.1% of hives. Whether they hold the line indefinitely is an open question. The economic value of WA-only varroa-free honey and pollination services is rising, which gives the state strong incentive to keep trying.

Treatment uptake — patchy, but improving

The shift from “kill all the bees” eradication to managed treatment has been hard for many beekeepers. The veterinary oversight requirements for synthetic miticides like amitraz and flumethrin caused initial delays, particularly for smaller hobbyist operators who weren’t accustomed to the registration framework.

The APVMA fast-tracked emergency permits for Apivar and Bayvarol in 2024, and these are now widely available. Oxalic acid vaporisation, which dominates European hobbyist treatment, has slower uptake here partly because the equipment is unfamiliar and partly because Australian beekeepers traditionally manage hives with less intervention than their European counterparts.

The Australian Honey Bee Industry Council estimates roughly 65% of registered commercial beekeepers in varroa-affected zones are now running active treatment programs. That’s up from about 30% a year ago. Hobbyist uptake is much lower, somewhere around 20–25%, and that’s a real concern because untreated hobbyist hives become reservoir populations that complicate management for everyone nearby.

Pollination service disruption

The 2025–26 almond pollination season was the most disrupted on record. Hive numbers moved into Victorian and NSW Riverina almond plantations dropped by an estimated 18% compared with pre-incursion baselines, partly because of varroa-related hive losses and partly because beekeepers were cautious about long-distance movement under permit conditions. ABC’s Rural Report covered several growers reporting yield concerns linked to under-pollination.

Apple, cherry, and avocado growers face similar issues. The almond industry’s investment in self-fertile varieties through Hort Innovation is starting to look prescient, but those programs are decade-long propositions and don’t solve the immediate gap.

There’s an emerging managed bee market dynamic worth watching. Pollination contracts are pricing in mite management overhead now, with rates up roughly 25–40% on pre-incursion levels. Some growers are exploring blue-banded bee and stingless bee operations as supplementary pollinators, particularly in protected cropping environments. None of these are at commercial scale yet for broadacre fruit, but the research investment from CSIRO and several universities has accelerated.

Surveillance technology gaps

The post-border surveillance toolkit hasn’t kept pace with the spread. Sentinel hive networks are still the workhorse, supplemented by sticky mat monitoring at apiary level. There’s been useful work on environmental DNA detection of varroa from hive debris, with promising results from a University of Sydney program, but it hasn’t moved into routine operational use.

Image-recognition tools for hive inspection have shown up in a few pilot programs. The more credible ones use mobile phone cameras to scan brood frames and detect mite presence at low densities. Whether these scale into a useful surveillance layer depends partly on data infrastructure — beekeeper apps that capture imagery and metadata in a structured way, then feed it back to government surveillance systems. AAP reported in March that DAFF is funding a national pilot on this exact use case.

What to watch through 2026

The November–March pollination season for the southern stone fruit industry will be a real test of how well the managed model is functioning. Beekeepers need confidence in treatment protocols, and growers need confidence in hive availability. Either of those breaking down meaningfully will create political pressure for a different policy response, though it’s unclear what that would even look like.

The biosecurity policy lesson from this incursion has been chewed over thoroughly. Where I’d push harder is on the post-border surveillance investment. We spent close to $130 million trying to eradicate varroa, and the surveillance footprint that detected it was barely sufficient. Other potential incursions — small hive beetle variants, tropilaelaps mite, asian hornet — would test the same systems. The lessons document from the National Biosecurity Committee is due mid-year. Worth reading carefully.
