The girl at the centre of the St Kilda AFL nude photos scandal says she is on the cusp of releasing video showing footballers taking party drugs and egging on a team mate to hit a woman.

Kim Duthie, 17, who made headlines last year after posting nude photographs of St Kilda players on the internet, said the new claims could "demolish" a different AFL club, which she did not name.

"I have so much evidence this time. I have gotten better with my spy skills," Ms Duthie told AAP on Tuesday.

She said she had video of some players taking party drugs, and another showing a player assaulting a woman in a Melbourne street at night.

"There is a clear shot of his face, but he is with some team mates as well and they are laughing and clapping him and egging him on and everything," Ms Duthie claimed.

AAP has not seen the video in question.

Ms Duthie, who has in the past admitted making up claims she became pregnant to St Kilda player Sam Gilbert, said this time she could prove she was telling the truth.

As well as releasing the nude photos, which it later emerged were stolen from Gilbert's laptop computer, Ms Duthie has also released video showing AFL player manager Ricky Nixon in her hotel room in his underwear.

She claimed she and Nixon were in a sexual relationship and that he used cocaine in the room, which he has denied.

Nixon has since gone into a rehabilitation clinic for treatment for substance abuse.

Following Ms Duthie's allegations, the AFL Players' Association (AFLPA) engaged leading lawyer David Galbally, QC, to investigate Nixon's actions.

Nixon could lose his agent's accreditation if Mr Galbally's report, which will be delivered as early as Wednesday, finds he breached his obligations as a player manager.

Ms Duthie told AAP she had spoken to Mr Galbally about her allegations.

She said she would release the fresh video to support her new claims after the lawyer's report was made public.

The 17-year-old also revealed she was about halfway through writing a book, although she was uncertain whether it would be an autobiography or a tell-all book about the AFL.

She said one publisher had already made an offer to print it, but she had not accepted any deal while she awaited to see whether a better offer emerged.
