Kuwarna has secured nominations for both Goal of the Year and Mark of the Year in Round Nine.
Izak Rankine capped a hot start to the final term with a typical flash of skill, soccering through a goal to give his side a 21-point lead.
Mark Keane, meanwhile, grabbed a game-saving mark late in the match to halt a siege of inside-50 kicks from Yartapuulti.
Kuwarna held on to a five-point lead to claim Showdown 57 and take a 29-28 lead in the ledger.
