Meanwhile, all-rounder Chris Woakes is also back in the Test side after a side strain led to him missing almost all of the Champions Trophy and the series against South Africa that followed.
Surrey opener Mark Stoneman and Hampshire spinner Mason Crane have been drafted into England's squad for the first Test against the West Indies, which begins on August 17 at Edgbaston. The 20-year-old has only played 25 first-class games.
Another who will be looking to confirm his ticket Down Under is Woakes, who was kept out of the South Africa series by a side strain picked up during the ICC Champions Trophy.
"Selectors would like of offer their congratulations to Mark Stoneman and Mason Crane who thoroughly deserve their opportunity in the squad", said National Selector James Whitaker.
The leg-spinner has always been seen as the future of England's spin options but the resurgence of Moeen Ali, man of the series against South Africa, means his Test debut may be further away than first thought.
Woakes made his return for Warwickshire this week and could be in a straight fight with Toby Roland-Jones for a bowling spot alongside James Anderson and Stuart Broad.
Jennings will return to Durham and look to recapture the form that had earned him selection late previous year.
Sheer weight of runs appears to have seen Stoneman force his way in ahead of Haseeb Hameed, who made his Test debut in India past year but has managed just one first-class score of more than fifty so far this season.
But it is the top order batting that needs to be sorted by England, who kept faith with Dawid Malan despite his struggles in his first two Tests, ahead of the biggest series of them all in Australia this winter.
The opening position has been a chronic headache for England since Strauss's retirement, but Stoneman should bring fresh zeal to the squad as he is arguably on the form of his life.
Stoneman has passed 1000 runs for the fifth consecutive season and averages north of 50 in the County Championship but, on the day before the Oval Test, he was instead playing in a rainy charity game at Reigate, Surrey, where one girl fielded in high heels.
