Kirra Dibb, who spent some time with Keary during a mixed club training session, will feature for the Prime Minister's XIII against Fiji on Friday evening before going on to play in her first Test for the Jillaroos against New Zealand at the end of the month.

Dibb, 22, spoke about her brief tuition with Keary after the captain's run in Suva on Thursday, while also revealing how she was overcome with emotion after finding out she had made her first Test team - via Instagram.

"Playing for the Roosters was an incredible opportunity and I was fortunate enough to play in the No.6 for the season,'' Dibb said.

"We did have one session with boys, where we played touch and Luke Keary and I were on the same team.

"It was kind of cool to pair up with him and see how the boys run it and be able to run off them. It was a really cool learning experience, the whole season. The boys have been really supportive, they sent us a couple of videos during the season, just wishing us luck before games.

"Luke Keary is amazing. He definitely deserves his Kangaroos jersey and unfortunately through the season with his concussions he wasn't able to put on the Blues jersey.

"He's really grown the last couple of seasons and he's going to lead the Roosters the next few years.''

Dibb has also grown to the point she will be the only PM's XIII player to back up against the Kiwis.

She was in the air flying to Brisbane when the Jillaroos team was named, and it was only after a teammate spotted the news on social media that Dibb realised her childhood dream had come true.

"It was a shock but super exciting and I got a little overwhelmed with those emotions,'' Dibb said.

"I have to focus on the Prime Minister's team first because we have a job to do.

"We flew up Monday to start camp and when I walked into the hotel, we dropped our bags and everyone was on Instagram. One of the girls turned around and said, 'Congratulations'. I said, 'For what?', and then I realised. I left the hotel immediately and sat out front and got a bit teary. It had been a long time coming.

"As a kid, all I ever wanted was to play for my state and my country and I have been fortunate enough for it to all happen in the one season.''

Dibb has also spent time fine-tuning her kicking skills with Daryl Halligan.

The Jillaroos will play in the curtain-raiser to the Prime Minister's XIII men's clash and kick-start proceedings again in Wollongong on October 25 before the Kangaroos-Kiwis Test.
