Byrne and his housemates 'inspired' by van der Flier's progress with Ireland
As housemates go, it is unlikely that there is a more competitive four in the country than Josh van der Flier, Adam Byrne, Tom Daly and Peter Dooley.
All four are close enough in age but it is Van der Flier who is leading the way on the international front. The flanker has been in terrific form this month and for his three Leinster housemates watching on, it shows what is possible.
Five Leinster players have made their Ireland debuts since the province last played a game. Joey Carbery, Garry Ringrose, Luke McGrath, James Tracy and Dan Leavy have donned the green jersey in the last few weeks, which is a fine testament to the work being done in the Academy.
Byrne is arguably Leinster's form player at the moment. The winger has scored four tries in his side's last two games, including a hat-trick last time out against Zebre.
The Kildare native has high hopes of his own and he admitted that watching his team-mates enjoy success with Ireland has inspired him.
"It's great," Byrne enthused. "Josh is my housemate, I've played with Joey and Garry underage. James Tracy actually grew up in the same village (Kill) as me.
"Then you have Dan Leavy, I played with underage as well, and Luke McGrath. It's unreal to see them getting their chances. They've worked so hard. I've seen them every day, doing extras, working really hard in training, and they're producing on the pitch and reached that next level.
"It's inspiring for the rest of us. Josh was home the other day, and getting to quiz him and stuff, and ask him all about the game. . . it pushes the rest of us on.
"It's great, especially in our house, we drive each other. It's really good to see the lads doing well, and hopefully they'll bring it back into Leinster, because it's a huge period coming up."
While Leinster have the Scarlets to worry about tomorrow night, Byrne is expecting Carbery and Ringrose to impress against Australia.
"When you see the hard work they've put in, I didn't doubt them for one minute that they wouldn't produce, or add to the team," he said.
