THE AFL might add two teams to its inaugural women's league, creating a 10-team competition.

An announcement is likely at the end of this month on the make-up of the league and its rules.

There is strong interest in the first national women's league, with 13 AFL clubs bidding for licences, including the Western Bulldogs.

Until now, the most likely set-up had been eight teams – four in Victoria and one each in WA, SA, NSW and Queensland.

But AFL CEO Gillon McLachlan admits they are still looking at the size of the league.

"It's plausible you could come out with 10 teams," he told Fox Footy.

"It may be eight and I doubt it would be six."

McLachlan said officials were looking at the number of players who would be available.

"They're having a look at the depth, what's coming through – they're looking at what's possible with the age limit," he said.

"If you speak to the people who know, there are probably a dozen or 15 17-year-old girls who would be among the top 50 girls, if they were eligible.

"So they're looking at age limits – is that the right thing to do?"
