EYRE Peninsula won three awards and a hall of fame induction at the 2014 South Australian tourism awards held in Adelaide on Friday night.
Adventure Bay Charters won its third consecutive major tourism attraction award and was inducted in to the prestigious hall of fame.
Ron Forster from Calypso Star Charters was also recognised for his involvement in Port Lincoln's local tourism industry and was presented with the outstanding contribution by an individual award.
Mr Forster has been instrumental in promoting Port Lincoln and the Eyre Peninsula as well as diving with the sharks to tourists around the world.
The Port Lincoln YHA won the award for best backpacker accommodation, which followed on from its golden backpack award a week earlier for best South Australian backpacker accommodation.
Since opening two years ago, the Port Lincoln YHA has been a standout in accommodation awards and continues to set the standard.
State tourism minister Leon Bignell said South Australia's tourism industry was rapidly growing and becoming an industry worth more each year.
"With record numbers of international and domestic tourists visiting South Australia, our tourism operators have a unique opportunity to help the state government achieve the goal of a tourism industry worth $8 billion by 2020," he said.
"Congratulations to (the) winners, and thank you to all nominees for their on-going contribution to tourism in this state."
