SEMEX'S jersey program manager Russell Gammon recently toured the country searching for brood cows and potential young sires with pedigree.
Mr Gammon, who is based in Canada, said the US was the major international driver for the breed, and within that was opportunity for Australia.
"While jersey sales are not the biggest portion of Semex's business, they are the fastest growing part of the business," Mr Gammon said.
Mr Gammon said he was convinced there were more bulls within Australia's population that could offer genetic diversity.
"We are focused on the US market and bulls that can compete in that marketplace," he said.
"We have a tremendous openness to working with Australian breeders to genotype Australian cows or interesting bull calves.
"They need a point of difference - they will probably have some index; a strong cow family behind them and be a good individual themselves.
"We have turned up the heat because we believe Australia definitely has something to offer.
"The strength of Australian cow families is a real selling point for us."
