Wide Comb dispute: The Wide Comb dispute was a landmark Australian industrial dispute.  Australian sheep shearers, represented by the Australian Workers' Union, opposed the alteration of the Federal Pastoral Industry Award to allow the use of shearing equipment that used combs wider than 2.5 inches.  Business and farming groups, such as the National Farmers Federation, supported the alteration of the award as they believed that the wider combs increased productivity.  The dispute culminated in a 10-week national strike by shearers in 1983.

The defeat of the AWU in the wide comb dispute has been widely cited as the cause of a decline in union membership and militancy amongst Australian shearers.
