Tony Šantić (born 17 October 1952) is a noted Croatian Australian thoroughbred owner and Southern bluefin tuna farmer. Career Born in Lastovo, Croatia, Šantić grew up in Port Lincoln. He gained initial success in tuna fishing there, and his early exploits in the fishing industry also included fishing for orange roughy in a leaky boat called the Vigorous off the coast of Tasmania. He went on to establish "Tony's Tuna International" in 1994. In the early 1990s, Šantić suffered financial hardship after tuna quotas were reduced twice. The tuna industry and a number of related businesses suffered while others shut down entirely. Santic's business survived, and by 1996 it had grown to include tuna ranching operations in Mexico, the Mediterranean and Port Lincoln. The development of ranching turned the tuna industry around, and Tony's Tuna International became one of the three largest tuna ranching operations in Port Lincoln. In 1997, Šantić decided to pursue his interest in horse racing, which ultimately led to three Melbourne Cup victories courtesy of a horse he named Makybe Diva. Šantić featured in the BRW Rich List in 2003, with an estimated personal wealth of $200 million. Fellow Port Lincoln tuna ranchers Sam Sarin and Hagen Stehr also featured on the list. By 2005, Šantić's horse Makybe Diva had won back-to-back Melbourne Cup races, and according to Robert Skeffington, editor of the BRW Rich List, Šantić was worth $150 million. In January 2010, an ammonia cylinder exploded at Šantić's tuna processing facility, destroying a shed and releasing ammonia gas into the atmosphere. No-one was injured during the explosion and Šantić was out fishing at the time of the event. Safework SA announced that they would investigate the incident. In 2012, Šantić's company, "Tony's Tuna International", initiated plans to trial an alternative ranching regime involving the capture of younger, smaller fish, and extending ranching time from six to 18 months. The initiative planned to make better use of the quota system, which allocates a total allowable catch to license holders, measured in tonnes. Later that year, Šantić and his wife Deslee became victims of fraud. The Adelaide newspaper The Advertiser was informed that $700,000 had been siphoned out of their business interests and that a 33-year-old Torquay man was under police investigation. As of 2015, Šantić remains the CEO of "Tony's Tuna International". Oceanic Victor Pty Ltd In 2015, South Australian Environment minister Ian Hunter revealed
