[3] On 26 January 2012 Jeffriess was awarded Member of the Order of Australia "for service to the fishing and aquaculture industries as a contributor to the sustainable management and harvesting of Australian fisheries and through national and international professional associations.
Since that time the industry has captured young fish in the wild and transferred them to pens in Boston Bay and Spencer Gulf where they are fattened up for market.
[1] Jeffriess has expressed his opinions to the media on a range of marine matters relevant to the southern blue fin tuna industry, aquaculture sector and fisheries management.
As of 2015, Jeffriess believes that the southern blue fin tuna stocks are being adequately managed, and welcomed increases to the Australian catch quota in 2014 and 2015 seasons.
Jeffriess has supported the need to research and manage New Zealand fur seal populations in South Australia and has described them as a major problem for tuna ranchers.
The organisation drew attention to the industry's dependency on small pelagic fish to feed the tuna and pointed to its potential to impact other species such as the little penguin.
