Conditions in England for the 2013 RLWC will be very different from the recent training the squad has had in Australia.
A couple of the boys were commenting on the heat at training today, it's going to be freezing cold conditions in England, much colder than training in the heat like this! says Hayne.
According to Jarryd, the Cup has opened doors for new nations and stronger teams.
I think last World Cup with Fiji, it opened up the mindsets of the other countries like Tonga and Samoa of their abilities. And if you look at the teams, I do think they have very strong squads.
Hayne sees the World Cup evolving into a bigger international platform for the game of Rugby League.
Its starting to be like a genuine World Cup where you don't go into a game expecting to win by 30 or 40 points," he said.
"A lot of NRL players are playing in the other teams which is one of a kind and hasn't really happened like that before.
Playing for Australia, Jarryd says he hasn't considered yet that he will be coming up against teammates from Parramatta including Semi Radradra and Api Pewhairangi and new recruit Lee Mossop in his pool matches.
I haven't thought too much about that, been focusing on training and the rest will look after itself. d
I'm feeling good - it's been a long break from the last game but I've kept training and keeping fit," he said.
It's the business end leading into the World Cup now and then the fun stuff begins with the games!
When asked about other teams in the competition, Hayne names Tonga as a team to look out for, and Fiji as a surprise packet.
Obviously Australia, England and New Zealand are the big three, and then Tonga the next biggest. And Fiji too - their outside backs are some of the fastest in the world.
The World Cup hype is starting to gather as Australia looks forward to the first match against England on Saturday 26th October at Millenium Stadium in Cardiff. Even Jarryd Hayne cant wait.
I think it's going to be exciting. Every team has an X factor which is unique, and it's going to make fans want to go there and participate.
Joining Jarryd Hayne at the 2013 RLWC are Eels players Api Pewhairangi, Semi Radradra, Fuifui Moimoi, Peni Terepo, Joseph Paulo, Brenden Santi and Lee Mossop.
Australia will then take on Fiji on Saturday 2nd November at Langtree Park St Helens and Ireland on Saturday 9th November at Thomond Park Limerick before the finals in mid November.
