Thompson, 20, was snapped up by the Power with pick No.4 in the 2008 NAB AFL Rookie Draft.
Now, he’s hopeful his 19-year-old brother will follow down the same path.
The pair moved to Adelaide from Port Augusta in 2004 and started playing for North Adelaide two years later.
Kriston, who was eligible to play U17s, lined-up alongside Wade in the U19s in his first season and also cracked one game in the reserves.
He added 11 reserves games to his tally last season and was also named in the Roosters’ best players in his league debut against Glenelg in round 14.
Port Adelaide already has three sets of brothers - Chad and Kane Cornes, Peter and Shaun Burgoyne and Justin and Matthew Westhoff - and narrowly missed out on securing a fourth in November when Geelong snatched Daniel Motlop’s younger brother, Steven, from its grasp.
The club also has two sets of cousins with Daniel and Marlon Motlop and David Rodan and Alipate Carlile.
Thompson was hopeful the Power would add to their brood of brothers later this year.
“Kriston’s fitter than me and he’s got good skills. Hopefully, he’ll get drafted. He’s only 19 and he’s already played a handful of league games,” Thompson said.
“He’s a back line player and we don’t have a lot of them at the club - we’re trying to get Marlon Motlop and Nathan Krakouer back there now.
“Kriston is a good defender. He reads the play well and can run off his opponent, so hopefully the club looks at him too.”
Thompson, who is from the same Flinders Ranges tribe as Swan Adam Goodes and Adelaide’s Jared Petrenko, is one of six indigenous players named in the Power’s 29-man squad to tackle the Swans in Canberra on Sunday.
The squad will be cut to 26 later in the week.
Vice-captain Shaun Burgoyne will miss the club’s NAB Cup opener with hamstring tendonitis.
Thompson said he was looking forward to playing alongside childhood hero Peter Burgoyne.
“I used to watch Peter when I was a bit younger. He was playing for Port when I was living in Port Augusta,” Thompson said.
“Just before I came down, I started idolising Aaron Davey from Melbourne. He made an impact straight away when he came into the AFL with his pressure inside 50m and his tackling and chasing. And that’s the type of player I want to be.”
