On 2 May 2007, Strettle was named as the Professional Rugby Player's Association Young Player of the Season. He was also named in the Sky Sports Dream Team for the Guinness Premiership season 2006–07, along with fellow Harlequin and England hopeful Mike Brown. Also in May 2007, Strettle was named in the England Rugby squad to tour South Africa. Unfortunately, he came down with food poisoning along with other members of the squad, which prevented him from starting in England's 58–10 record defeat to South Africa.
