They hold AFL draft camps in the USA.
This is from the Wikipedia page of the Collingwood Premiership winner Mason Cox:
Cox studied engineering at Oklahoma State University, graduating in 2014. While studying, he started playing basketball as a hobby.
Cox was invited to attend the 2014 US International Combine for potential Australian rules footballers, in Los Angeles in April 2014 despite knowing very little at all about the sport. After impressive performances in the skills testing, he travelled to Australia for a second combine and on May 30, 2014, was signed by the Collingwood Football Club. AFL teams Port Adelaide, North Melbourne, Richmond, and Fremantle were also reported as having shown interest in recruiting Cox.
Cox made his AFL debut on April 25, 2016, in the annual Anzac Day match against Essendon. Within the first 80 seconds of the match, he took his first mark and scored the game’s first goal with his first kick in the AFL. Collingwood went on to win the match by 69 points.
Here’s something you’ll never read:
“Joe Bloggs trialled for football at age 23, while having grown up playing Aussie Rules in regional Victoria and having never played football. He impressed the scouters and was signed by Manchester City, playing for the reserve sides initially then making his Premier League debut 2 years later and went on to become a Premiership winning footballer”.
Face it. If you are tall, athletic, and know how to catch a ball, you can practice Aussie Rules for a year or two and debut at the highest level of the game in the AFL. The skills required for Aussie Rules are generic.
edit: yeah I get that you were asking if AFL were still poaching players from the NRL, and no I don’t think so. Mason Cox popped up on my feed when he jokingly posted “World Champions” after winning the Grand Final. That’s when I read up on it and found out the AFL hold draft camps in Europe and USA and invite athletes from various sports to see if they’d be a good candidate for playing in the AFL.
