Last week Lui was charged by police with assaulting partner Taleah Backo after three straight days of post-season celebrations with Tigers teammates.
Club officials agreed for Lui to return to Queensland and be comforted by family and friends ahead of his October 7 court hearing.
But rather than keep a low profile, Lui took part in the inaugural Queensland Murri league carnival on the Gold Coast and inspired the Southern Dingoes to a 44-24 final victory over Purga Wagtails.
The three-day drug and alcohol-free carnival, organised by former Maroons great Tony Currie – and endorsed by the ARL and QRL – involved 20 Aboriginal and Torres Strait Islander teams and featured NRL players Chris Sandow, Dane Gagai and Yileen Gordon, and former star Nathan Blacklock.
The incident disappointed Tigers chief executive Stephen Humphreys, who was with Lui until 3am last Tuesday at Burwood Police Station, and he is keen for the 21-year-old to give an explanation when he returns.
The Tigers have stood Lui down from all club activities and will await the outcome of his court hearing before deciding on his future.
