Tasmanian Sam Beltz won a silver medal in his first appearance for Australia at the 2003 World Championships. His lightweight double sculls combination with fellow Tasmanian, Tom Gibson, in 2006 led to two fourth place finishes at the World Championships (2006 and 2007). After Beltz recovered from a broken coccyx in February 2008, the pair raced at the 2008 Beijing Olympic Games and finished 10th.
He returned to Olympic competition in 2012 as a part of men’s lightweight four alongside compatriots Anthony Edwards, Ben Cureton and Todd Skipworth. After finishing second in their heat and then third in their semi-final, the Australian team finished less than a second behind bronze medallists Denmark in fourth place. South Africa claimed gold with hosts Great Britain winning the silver medal.
