The 28th Brigade was a formation of the Australian Army during World War II. Raised in April 1941, the brigade consisted of Militia units who were assigned to carry out defensive duties on the New South Wales Central Coast. After being mobilised for war in December 1941, the brigade mounted defensive duties throughout 1942 and 1943, defending against a possible Japanese invasion. As this threat passed, the brigade's role diminished throughout 1943. Eventually, the brigade was disbanded in December 1943 having never seen combat. Its constituent units either amalgamated with others, or broken up as reinforcements.
