Nic Maddinson is an Australian cricketer. He is a left-handed opening batsman who is currently signed with the New South Wales Blues in Australian domestic cricket.

Hailing from the South Coast, Nic was part of the New South Wales Under-19 side that won the Australian Under-19 Championships in December 2009.

Two months earlier, he had topped the batting averages for Australia in a home series against Sri Lanka Under-19s, when he averaged 72 and scored a brilliant 133no at a run-a-ball, in a 50-over match in Darwin.

Nic used these performances to get selected for the Australian Under-19 side that flew to New Zealand to compete in the ICC U19 World Cup in January 2010.

During the Tournament, Nic opened the batting for Australia and was part of the victorious side that defeated Pakistan by 25 runs in the final at Lincoln, to lift the trophy.

Nic also had an excellent season with the Sutherland Grade Club, where he scored 604 runs for the year at an average of 46.46. He scored two centuries but none was more vital than his 137 in the semi-final against Eastern Suburbs that helped Sutherland reach the Grand Final, where they eventually lost to St George.
