Brell said he knew one of the people, so he let them inside.
"Everyone was having a good time, everyone was chill," he said.
"But then they started going through our rooms, searching through our stuff."
Brell said he asked them to leave, but claimed that after the group went outside he was threatened and hit in the back of the head.
Brell suffered a gash to his head and bruises to his back from a baseball bat.
Video provided to 9News showed a brawl taking place outside the house.
One person pulled out a knife, allegedly stabbing the 16-year-old.
Another person could be heard begging for the attack to end.
A group was then seen fleeing, with emergency crews arriving soon after.
The injured teenager was taken to hospital in a serious condition with stab wounds to his chest and abdomen.
A blood-soaked shirt was left behind, and a neighbour's vehicle was vandalised.
Police are still searching for the group responsible.
Police have been provided with security camera footage from nearby homes.
