 Hannah Mouncey   28  who previously played at local level in Canberra  hopes to take to the field in the state of Victoria this season.
Before  she  began  her  gender transition in 2015   Mouncey  played for the Australian men's handball team.
The AFL's decision means  she  can now partake in any of its affiliated state leagues during the 2018 season.
In a statement uploaded to Twitter   she  thanked  her  supporters - but not the AFL itself.
"I think it would be highly inappropriate for me to thank the AFL for allowing me to do something open to every other Australian  which the science and research has supported all along "  she  said.
Despite the decision made in  Mouncey 's case  the AFL has still to define its national framework for gender diversity.

The survey  offered by public broadcaster ARD  showed Merkel's popularity has plummeted by 10 points to 48 percent -- her worst showing since late 2006.
 Of the 1 000 people surveyed by Infratest dimap this week  58 percent said they thought the previous government of Merkel's conservatives and the center-left Social Democrats would be better than the current coalition Merkel formed in October with the Free Democrats.
's conservatives and the center-left Social Democrats would be better than the current coalition Merkel formed in October with the Free Democrats.
 Merkel has been under pressure for months. Within Germany  critics noted that her new coalition so far has little to show for its efforts in the seven months since it took control  other than the unpopular Greek and euro rescue packages. On the international stage  Merkel has been criticized for dragging her feet on helping Greece.
 The chancellor has already scrapped plans for promised tax cuts  but still faces a huge federal budget deficit. Her government is to decide on spending cuts and  possibly  even on tax hikes within the next 10 days.
 Only 34 percent said Merkel's government has made the right decisions to counter the crisis.
 The one member of Merkel's Cabinet who enjoys steady support is Defense Minister Karl-Theodor zu Guttenberg  with 61 percent of those surveyed applauding his work.

"Did they cut more calories from their diet ... or did they become more physically active?" asked study author Kevin Hall   a senior investigator with the National Institute of Diabetes and Digestive and Kidney Diseases.
 Hall  had been "puzzled by how quickly the contestants were losing weight." So he contacted the show's physician and began studying the season eight contestants.
Early on   Hall  observed that weight loss was better predicted by food intake  not physical activity alone. But in the long term  the opposite was true.
"You have to be very physically active in order to keep the weight off  " Hall  said.
 Hall 's findings echo previous studies that promote more exercise for long-term weight loss maintenance. However  experts caution that doesn't mean people can neglect their diets in the long run  either.
This method  however  was not able to tell how much of the physical activity was due to normal daily activities -- like cleaning the house or walking the dog -- versus following a workout plan   Hall  said.
Six years later  however  the contestants' resting metabolisms still hadn't sped back up   Hall  showed in a study last year.
For  Hall   metabolic changes are just one part of the puzzle. Genetics may also play a role  as well as social factors that can make it hard for some people to incorporate so much exercise in their daily lives.
 Hall  added that it's not necessarily those who were most physically active during the competition who kept it up six years later.
