The 29-year old was sacked by North Queensland and received a lifetime ban following a physical altercation with his partner Ainslie Currie in a Townsville casino.
Wilkin admitted he felt sick to the stomach when he heard about the incident and the decisions that followed which included the RFL choosing to respect the NRL’s life ban decision.
However, Wilkin, who played with Barba last year, believes the league’s previous soft approach to serial offenders and lack of representative level talent in the UK game will one day see him return.
“There is no precedent set over here by the RFL (about banning players),” Wilkin told the BBC Rugby league podcast.
“Over here we are not as aggressive as the NRL with policing player’s code of conduct.
“There are a lot of second chances handed out and players don’t realise how lucky they are.
