Tullamore NSW


In 1974 Robert Mortimer had a vision of the type of sheep he needed to suit the Australian climate and conditions. 

Robert found great difficulty in sourcing what he needed and so, after discussions with a good friend an idea formed to create a ram breeding group that could have access to top rams or elite AI sires straight away. And so Centre Plus began – a breeding group where progeny testing of the top animals could begin immediately.

Fast forward 44 years to 2018 and the Centre Plus Merinos genetics are proven. They are time tested through years of intense University and private research, meticulous record keeping and analysis. 

Centre Plus specialise in producing a merino with high productivity, superior wool and characteristics. The meticulous scoring and recording of each animal’s traits, combined with full DNA testing and the use of genomics creates an environment where each animals’ potential  is maximized.

Today Centre Plus is an innovative merino stud, focused on producing the exceptional all purpose merino.

Robert Mortimer

Robert Mortimer Robert 
Nucleus & Breeding Manager/Member.

There’s a saying around the Merino industry “If it can be measured, Robert Mortimer has measured it.” Robert owner and manager of the Centre Plus Nucleus Stud in Tullamore NSW. Robert a second generation farmer, he and his wife Pam have worked as a team for over 50 years to ensure that their flocks provide cutting edge genetics and profitability for success. Robert and Pam are part of a proud tradition, a three generational family partnership including their sons Doug, Mark and families making their living in the sheep industry. 

Robert is the Nucleus & Breeding Manager for Centre Plus Merinos. Centre Plus began in the early eighties as a group of people who joined together to produce more profitable sheep genetics. The core breeding program is based on the assumption by founding members that a self-replacing dual purpose merino flock has the best potential to continually increase the bottom line profits of breeding shareholders. Robert says over the years the program has evolved and developed after experimenting with various genetic evaluation strategies and products.
