State Outlooks for January 2021

Weather conditions have varied greatly from coast to coast throughout early summer. Our correspondents have noted the need to monitor worm egg counts closely.

New South Wales
>> full report

Areas which have been warm and wet over the holidays are likely to see high numbers of barber’s pole worm. Test regularly and start planning low-risk lambing and weaning paddocks now!


>> full report

Summer has been wet and so far relatively cool. Worm eggs and larvae remain viable on pastures for longer under these conditions. Regular worm egg count testing is vital, especially after rain.

>> full report

If you’re in an area which has received good rainfall, keep an eye out for barber’s pole worm and monitor sheep at regular intervals. If things stay wet, worm issues may well continue through autumn and into winter.


Western Australia
>> full report

Things in WA have been hot and dry, so worm contamination on pasture is likely to be quite low, but the weather may change. A strategic drench may help keep worm populations low if stubbles are available to graze.

>> full report

Monitor worm egg counts to help time a second summer drench — it may come earlier this year due to the cooler and wetter conditions. Keep an eye out for liver fluke, as recent rain may have contributed to an expansion in their habitat range.


South Australia
>> full report

Conditions are looking good in SA, though worm egg counts in some mobs might warrant a tactical drench. Consider the impact of your summer drenching decisions on contamination risks heading towards autumn.
