"If we were to have an 18th team, we would have to have a good hard look at a second New Zealand team.
"Eighteen teams is a lot more dynamic in terms of how you can configure the draw. It means another rivalry in another key market for us, wherever that might be. It means new fans. It means we could have conferences and pools. These are all good options to explore."
Abdo and ARL Commission chairman Peter V'landys are expected to begin meeting with Brisbane consortia in the coming weeks with the aim of providing clarity on expansion by the middle of the year.
The leading contenders to become the NRL's 17th team are the Redcliffe Dolphins, who have lodged a Brisbane Dolphins trademark, the Brisbane Jets — a coalition of the Brisbane Bombers and Ipswich Jets — and the Easts Tigers-backed Brisbane Firehawks.
Queensland Origin hero Cameron Munster has already been flagged as a potential signing to be the face of the franchise.
"If another Brisbane team comes in, I won't say no to going back home," Munster told News Corp recently.
"I do see myself moving to Queensland after football and if a second Brisbane team comes in, I could go back earlier than expected.
"I wouldn't say no to that (joining a second Brisbane team) … for sure."
V'landys said the NRL would not expand to Brisbane if it thought the market would be crowded and existing Queensland teams the Broncos and Gold Coast Titans would be hurt by the move. But the most powerful man in rugby league is confident a new team will only be a positive addition.
"It's very realistic to say that we'll have a second team in Brisbane in 2023," ARL Commission chairman Peter V'landys told the Sydney Morning Herald last month. "From what I've seen and the presentations that have been given to me, they are well advanced.
"The one thing that I am impressed with is how advanced these bids are. They are not mucking around. They are serious. If we came to a decision in June this year, that would give them a year-and-a-half. It's plenty of time. If it's going to happen, it's going to happen mid-this year.
"I'm not going to do it if it's going to hurt the game. It's got to benefit the game."
