It is less a case of "show me" than "show who?" the money, after the Brisbane Lions' Irish rookie Colm Begley roosted a supergoal in last week's NAB Cup semi-final win over Geelong.

NAB donates $1000 to the junior club of any player who kicks a supergoal during the pre-season competition. The only problem in Begley’s case is that he doesn't have an Australian junior club, having come direct from Ireland to the Lions in the 2005 rookie draft.

On Tuesday afternoon it was still no clearer who would benefit from Begley’s bomb. Begley himself, preparing for Saturday's NAB Cup grand final against Carlton, wasn’t overly concerned - although the likeable 20-year-old from County Laios said Stradbally, his original Gaelic club, would be his first choice for the donation.

"They wouldn't spend it over the bar or anything like that," Begley chuckled when asked what he thought Stradbally might do with the funds.

"If they get it I'd like to see them do something for the kids - whether that be a training camp, new kits or something with the facilities. The president of the club helped me out quite a bit when I was coming through the ranks and I'm sure he'd be able to put it to good use."

Something Begley has been putting to good use throughout the NAB Cup is the running ability he initially developed in the Gaelic game. When he first arrived at the Gabba in December 2005, most observers thought his future lay as a mobile defender, in the mould of his compatriot, Sydney star Tadhg Kennelly.

After a debut season spent learning the oval-balled game and several positions, he's happy to be settled in the back half of the field, where he can put his athleticism and endurance to good use.

"To begin with almost everyone thought I'd play at half-back. But during my first year I ended up playing a lot of positions - in the midfield and a bit at half-forward - and I didn't really have a set position," Begley explained.

"Last year, every game was an experience for me. But I'm happy now to have settled at half-back. I have my head around things and I know my role - I have a much better idea of what's going on out there than I did a year ago.

"Coming from a Gaelic background has definitely helped. Running, playing on and handballing is a big part of our game and it has probably made it easier to back myself. [Coach] Leigh [Matthews] has been encouraging me to run whenever I can and back myself."

Begley's supergoal was certainly evidence of just that. Streaming forward from defence, he left fly with a left-foot bomb from 55m that split the big sticks and gave his teammates a few chuckles.

"It was a great feeling. I didn't think it would go that far and then I thought it was probably going a bit too far to the left," he said.

"Then I looked up and realised it was actually going to go pretty close. All the boys came running in and they were pretty excited - getting around each other like that is something we've been looking to do a bit more of this year.

"There was a little bit of laughter afterwards when everyone realised what had happened."

Like the rest of his young Lions teammates, Begley is excited about the prospect of a first-ever NAB Cup joining the premiership cups in the Gabba trophy cabinet. The Lions have started underdogs in every round so far but Begley says the betting hasn't reflected the level of confidence in the playing group.

"It's a great feeling to be getting ready for a Grand Final. I've seen some of the video clips (of the premierships) and they are amazing," he said.

"Right from before the first game there was a really good vibe. And that's continued on - there is a really good atmosphere, it's a really united team and there is a lot of enjoyment every game.

"We've done well to get this far and hopefully on Saturday we can play the way we have been and execute well again. There is a lot pride in the Lions and it would be fantastic to win."
