Gilchrist's attacking batting was a key part of Australia's one-day success, as he usually opened the batting. He was a part of the successful 1999, 2003 and 2007 Cricket World Cup campaigns. Gilchrist's Test batting average in the upper 40s is unusually high for a wicket-keeper. He retired from Test cricket at 45th on the all–time list of highest batting averages. At the end of his Test career he had established a Test strike-rate of 82 runs per hundred balls, at the time the third highest since balls were recorded in full. His combination of attack and consistency create one of the most dynamic world cricketers ever, playing shots to all areas of the field with uncommon timing. He was second on the all-time list of most sixes in Tests at 100 with only Brendon McCullum ahead of him with 107. Gilchrist's skills as a wicket-keeper were sometimes questioned; some claimed that he was the best keeper in Australia whilst others that Victorian wicket-keeper Darren Berry was the best Australian wicket-keeper of the 1990s and early 2000s. Gilchrist attributed his batting techniques from early training with his father, where he would defend shots, sometimes only gripping the bat with his top (right) hand, and would end a session to simply play attacking shots with tennis balls to end on a positive and fun note. He also adopted a naturally high grip where both hands were closer to the end of the handle for more top hand control.
