Vickery, 23, had his first training session with the club this week and is set to feature for the Rhinos in their pre-season friendlies as he looks to earn a permanent deal.
“This is a great chance for me to step up to another level. My manager told me about the interest from Leeds and I was so excited about the chance to join the best team in the competition. Hull FC offered me a deal during last season but things didn’t work out in the end however it is great that I can now come over here and show what I can do.”
Although he didn’t make a first team appearance during two seasons with Gold Coast, he did score 17 tries for their feeder club Tweed Heads last season.
