The 25-year-old has played 70 NRL games, and has also represented City Origin, but feels his best rugby is still ahead of him.
“I’m very excited, I haven’t been this excited going into a season for a long while so I’m looking forward to the opportunity and a new challenge,” Allgood told Rovers’ official website.
“A lot of players wait to the end of their careers to head over to Super League but this chance has come up for me now. I’m 25, I feel like my best football is ahead of me and I’m happy that’s going to be at Hull KR.
“There’s a few Australian boys that have gone over there who I’ve spoken to and a few of them actually played for the club. Blake Green has got nothing but positive things to say about the place, about the staff and what a great environment it is so they are great words to hear.
“My goal is to come over there and just to play good football. I’m jumping out of my skin, I’m that excited to get into training and to play footy. I feel like a kid again and my main focus is just to get over there on the field with the boys.”
Allgood is also looking forward to linking up with some familiar faces when he arrives in east Hull soon, after receiving his visa.
“Ken Sio is over there now and he’ll be my tour guide I’m sure!” he added.
“We played together at the Eels for a few years but he’ll be like a local when I come over so he can show me round the place.
“Mick [Weyman] is another quality player. He’s somebody I’ve watched when I was younger and also had the chance to play against in the NRL, so it will be good to play alongside him.
“I’m a bloke who tries to do his best and do whatever he can for his teammates. I’ll definitely be keeping the training up and keeping myself in good nick while the paperwork comes through and hopefully my manager and the club can get that sorted as quickly as possible because I can’t wait to get over there.”
