The trio have been training for the past six months for the NSW event, with Jake doing his sessions with his father when he comes back to town on weekends.
Jake will make his fighting debut in the Colts (Under 21) division, while Hood enters the Open Men's and Boswell competes in the Open Women's.
The three of them will not know until they arrive how many Australians have registered for each grade.
"You could have one fight in a day, or you could have three," said Hood.
Watching them both will be the hardest part, although Hood told his partner and son they should just enjoy the moment, and not feel any pressure to perform well for him as their coach.
"I've told them in no uncertain terms....it's all about them, they're the ones out there."
