During World War II, which battle denied the Japanese the opportunity to attack Australia?

The Battle of the Coral Sea in May 1942 stopped Japan’s advance toward Port Moresby in New Guinea, a move that could have threatened Australia. The battle denied Japan that opportunity, even though it was fought largely by aircraft carriers without the opposing fleets directly seeing each other. Midway was a major turning point in the Pacific, but it was not the battle that halted this advance toward Australia.
