Development of the Gromark began in 1965 in northern NSW, Australia.

 

The Gromark is fixed at approximately 50 percent Corriedale and 50 percent 50 percent Border Leicester. It is a dual-purpose sheep which evolved from objective selection for high growth rate and fertility with final selection being based on visual criteria – wool quality, frame and carcass attributes.

 

The Australian Gromark Breed Society was formed in 1979 and has established rules expressing a strong commitment to recording of performance.

 

The Gromark is a large-framed breed (ewes average 80 kg/175 lbs) producing large lean lambs and good fleeces with wool fiber diameter being about 80 microns.
