England head coach Eddie Jones says next week's training camp in Brighton represents a "great opportunity" for players like Danny Cipriani to earn a place on the upcoming tour of Australia.
The Grand Slam winners take on the Wallabies in a three-Test series in June, live on Sky Sports, which will provide a chance to gauge just how far they have come under Jones' guidance.
Preparations for the tour are set to be stepped up between 17-19 May, when a 26-man squad, which includes eight uncapped players, will descend on Brighton for a series of training sessions.
Players from Premiership semi-finalists Saracens, Exeter, Wasps and Leicester will not be at the camp and Jones is eager to see how some of his new call-ups fare.
"It is a really important camp for us," he told Sky Sports News HQ. "They have all got a great opportunity. Competition for places is intense and we have probably got 40 players competing for 30 spots."
Regarding some of the promising forwards he was looking forward to working with, he added: "(Charlie) Ewels is a good young lock who has been doing well for Bath.
"(Teimana) Harrison has come out of the woodwork for Northampton. Pre-Christmas he was not that outstanding but he must have eaten something at Christmas, because his play since has been pretty good!
"Kyle Sinckler is a young Harlequins prop with great athletic ability and he is going to be competing hard."
An interesting name among the backs is fly-half Danny Cipriani, who, despite missing out on the World Cup squad, is firmly back in England contention after a lengthy spell in the wilderness.
"Danny has got (rival fly-halves) Owen (Farrell) and George (Ford) in front of him but he has a great opportunity," Jones added.
"He has great talent and is one of the key reasons Sale have finished so high in the table. I am excited to see what he can do."
Two players who will not be at the camp are back rowers Sam Underhill and Steffon Armitage, but Jones says they could well be members of the squad in the future.
England cannot pick players who are not based in the country unless there are exceptional circumstances and the 19-year-old Underhill is playing for Ospreys in Wales, while he studies in Cardiff.
But Jones said: "He has been playing pretty well for Ospreys. We have got the situation that he plays outside of England and we have got to sort that situation out.
"I think we are close to a resolution and there is no doubt he will be selected in an England squad in the next six months."
The highly-rated Armitage has been playing in France but has been reportedly linked with a move to Wasps, which could see him back in international contention.
Asked if a returning Armitage might be in his thoughts, Jones said: "If he comes back and manages to get in the Wasps side, which will be difficult to do.
"If he gets fit and he wants to play for England, then we will consider him. He is certainly a talented player."
