According to a report in ESPNCricinfo, the 10 players will take part in 60 hours of community service and also attend a counselling programme.
Cricket PNG chief executive Greg Campbell said: "The behaviour of our players is not what we would expect from international cricketers of any age. The players have expressed sincere regret at their actions and in addition to their suspension from cricket, they will undertake a comprehensive rehabilitation programme over the next 12 months."
ICC General Counsel and COO Iain Higgins added: "This has been a highly unusual incident by a group of young players and I would like to thank Cricket PNG for acting swiftly and decisively. It sends out a clear message that the sport will not tolerate this sort of behaviour at ICC events.
"We are obviously extremely disappointed with the behavior of the players, but we are satisfied that Cricket PNG has delivered a suitable and proportionate sanction and programme for rehabilitation. Therefore, the ICC will not take any further action against any of the players."
