Queensland's wingers, Wendell Sailor and Scott Barton are bigger and heavier than the opponents Sean faces in the Celtic League.
Sean said: "I found their wingers much bigger - we're used to more nippy side- steppers in the Celtic League - but I don't get star-struck, to be honest. The fact they were bigger though gives us more to learn from. Hopefully, we will learn from it and step it up.
"But they (Queensland) have been playing for the last 13 or so matches as a team and we've been together for one as a development team. Yes, we lost, which is disappointing, but this has certainly helped my confidence, getting out there and playing a tough game with the Scotland jersey on - it's something you always want to do - and it's about becoming better now.
"It was good to score, but it would have been nice to have kicked off the tour with a win and that's what we've got to get now."
