Dollapi joined the London Skolars from the London Broncos on a dual registration on 12 February for the 2013 season following a partnership agreement signed by the two clubs which saw 5 Broncos dual register for Skolars.[6] He featured and scored a try in Northern Rail Bowl Final against North Wales Crusaders, however Skolars lost the game 42–24.[7][8][9]
Dollapi made his Super League début on 1 April 2013 against Warrington Wolves at Halliwell Jones Stadium. He came off the bench to score the last try of the game from close range, a game which ended in a 54–20 defeat for the Broncos.[10][11][12][13]
He signed a new one-year contract with the London Broncos on 17 November 2014 for the 2015 campaign in the Championship.[14]
