2Transitional arrangements that have applied for 12 months finished on 30 June 2017. From 1 July:
•
Herds from the previous CattleMAP and Free Zone (WA) transitioned to J-BAS 8 (if they
implemented a vet oversighted on-farm biosecurity plan)
The former Protected Zone, Beef Protected Area and Beef Only herds transitioned to Level 7
•
(if they implemented a vet oversighted on-farm biosecurity plan)
•
Producers wanting their herds to remain JBAS 7 or 8 will need to implement the first
triennial Check Test by 30 June 2018.
Herds that hadn’t implemented a plan by 30 June 2017, defaulted to J-BAS 6
•
•
Producers whose herds defaulted to J-BAS 6 but want to maintain J-BAS 7 can complete their
vet-oversighted plan as soon as possible and commit to implementing the first triennial
Check Test by 30 June 2018 at the latest.
•
Herds which did not qualify as J-BAS of 7 or 8 in the transitional period but have had no
previous infection with JD and have implemented a Biosecurity Plan were given a score of 4.
Once these herds have maintained a Biosecurity Plan for at least 5 years (with no occurrence
of JD), they can advance to score 6.
•
Herds that were previously infected or suspected of being infected moved to the score
appropriate to time since last clinical case or 0 if no plan is in place.
Producers should use the JD in Cattle Biosecurity Checklist (available at:
) for more information.

How does a producer develop a Biosecurity Plan for J-BAS?
Plan templates are available on the
LBN
and
AHA
websites. For producers wanting to maintain or
achieve J-BAS 7 or 8, ask a cattle veterinarian about BioCheck for on-farm biosecurity planning
purposes. The National Farm Biosecurity Reference Manual - Grazing Livestock Production is
available from the website
and provides a guide to use for the
property biosecurity plan. It has specific livestock and animal health management sections which
outline suggested practices to be included in a cattle Biosecurity Plan. All plans should include the JD
in Cattle Biosecurity Checklist.

‘overseen’ means the vet has discussed with the person completing the Plan the biosecurity risks associated
with the property and ways of managing those risks. The vet is to sign as confirmation of having had this
discussion.
