The Shackell Shield is a 4 x 50 metre relay (mixed teams or one sex i.e. male team or a female team) event run and the same night as the Shackell cup, but this one is an event for the primary school children. This event is a relay race against each school. Each school entering a team must enter it on the night before the heats are organised. Once the heats are organised each race is called out over the PA system and the announced team must line up behind the corresponding lanes ready for their swim in the heats. The fastest 7 teams go through to the A Final and the next fastest 7 go through to the B Final. This event is also a scratch event.
