The league announced the competition this month but key aspects were unconfirmed, including which teams would be involved and how players would be recruited.
The NRL has received interest from most clubs to set up women's teams and will begin a tender process in January, which is expected to last around two months, ahead of the competition starting towards the back end of the men's season.
Cronulla-based McGregor, who played at centre in Australia's World Cup final triumph over New Zealand, said playing in the women's premiership was a top goal for her career.
But finding out her future as early as possible was critical for her situation.
"I'm hoping to go somewhere not too far away. I'm not sure what the system is. There may be a drafting system so I might have to go somewhere else," she said.
"I have a son, so that would be tough. But we're working with the RLPA (Rugby League Players Association) to make sure it's favourable with us as players.
"We don't know much yet but I'm sure we will be informed soon. The sooner, the better."
The competition will see 40 Jillaroos, who will receive pay deals on top of their national women's championship match fees, split among up to six teams to contest the inaugural season.
Brisbane and the Warriors expected to be included, with geography and the club's resources understood to be among selection criteria.
Apps, a St George Illawarra club ambassador, moved from NSW country town Bega to Wollongong this year to further her rugby league career and was optimistic she wouldn't have to move again.
"I'm really hoping the Dragons get a team. I'll be living down there so it makes sense that hopefully I can slip in with them," she said.
"We do have a lot of strength in that region.
"It's all up in the air and we're not sure when it's all going to happen, but hopefully sooner rather than later."
Speaking at the Jack Newton Celebrity Classic, both players expressed surprise at the competition being launched for next year having previously understood it was at least two years away.
But Apps believes the league could include at least 10 teams in five years' time.
"The development over the last four years, since I've been involved, has skyrocketed," she said.
"The number of women and girls playing is the highest growing area of rugby league.
"The more exposure we get, the more girls will want to play."
