Former high flying Lion Justin Leppitsch has given aerial tips to Brisbane wingers Denan Kemp and Kaine Manihera ahead of Sunday's NRL showdown with Canberra.

The 227-game AFL triple-premiership winner took time out from his aerial coaching role with the Lions to work with Brisbane's wingers on Thursday following the upsurge in tries scored from kicks this season.

Storm stars Israel Folau and Greg Inglis are spectacular in climbing above rivals to drag down bombs.

Folau even attributed a freakish try during the recent Origin series to some extra training work with AFL clubs in Melbourne.

Halves Mitchell Pearce and Braith Anasta have perfected kicking games this season that have led to a glut of tries for the Roosters.

The Raiders got in on the act bagging five tries last weekend against the Titans off kicks, which have become more and more prominent as defences become harder and harder to crack.

The increase in tries from kicks has been so dramatic that there's even been discussions about devaluing them from four points or even ruling out conversion attempts.

"The Folau try was probably what brought it all on," said Leppitsch after schooling Brisbane's wingers during a closed training session at Suncorp Stadium on Thursday.

"A lot of people in AFL have been saying it should have happened a long time and I think you saw the first glimpse of it with the Folau try.

"If tries like Folau's keep happening, I'm sure rugby league will look to have aerial coaches fulltime to give players advice."

While AFL players didn't know a lot about rugby league, Leppitsch said they were experts in aerial play and how to position their bodies in contests.

"It's a pretty big part of our game," said Leppitsch, who made the shift from playing forward to establish himself as one of the game's toughest defenders.

"We didn't talk about taking the ball overhead or on their chest, that's a skill that has to be learned over time.

"It was more how to position themselves in that aerial contest and where to put themselves to give them the best chance.

"If they don't win the contest, at least make sure the other winger doesn't."

Brisbane fullback Karmichael Hunt said given AFL is based around catching the football and, having Leppitsch handing out some tips was a good move.

"I'm sure the boys will get a lot out of the session with him.

"When we come up against teams who've got tall wingers it will be good to have some professional advice.

"It's got a lot to do with confidence too. Guys like Izzy (Folau) and Greg (Inglis), they're catching the ball with their hands up high which adds an extra metre onto their height."
