The Rugby League Players Association is confident a pay deal can be reached within weeks, but warn strike action is still on the cards if no resolution is struck.
Almost 300 players met in person and via video conference to be presented with the NRL's latest Collective Bargaining Agreement offer in Sydney on Monday night.
Negotiations have dragged on for 14 months with a October 31 deadline in mind, and the RLPA warns boycotts could begin by skipping commercial activities through next month's finals series, including the captain's call and the Dally M awards ceremony.
Players didn't directly discuss the end-of-season World Cup on Monday, but skipping the tournament is still a possibility, as is challenging the league's salary cap through the courts.
"We think that by locking ourselves away we can get this deal done. But having said that we can't rule out further action," RLPA chief executive Ian Prendergast said.
