England suffered a 5-0 Test series defeat by Australia in 2013/14 when the Ashes were last up for grabs, with the fall-out from that thrashing leading to the international exile of star batsman Kevin Pietersen.
However, Australia have not won the Ashes in England since 2001, with England triumphing on home soil in 2005, 2009 and 2013 against their oldest rivals.
This season’s Ashes starts in Cardiff on July 8.
“The squad for the first Test will be announced within a few of days of returning from the camp,” said former opening batsman Strauss.
One of Strauss’s first acts in his new role was to sack former England coach Peter Moores and bring in Bayliss, while appointing assistant coach Paul Farbrace to a caretaker position in the intervening period.
Under Farbrace, who was Bayliss’s deputy when the Australian was head coach of Sri Lanka, England drew the Test series with New Zealand and are currently all square at 2-2 in the one-dayers ahead of Saturday’s deciding fifth match.
England pre-Ashes training camp squad: Alastair Cook (Essex), Moeen Ali (Worcestershire), James Anderson (Lancashire), Gary Ballance (Yorkshire), Ian Bell (Warwickshire),Stuart Broad (Nottinghamshire), Jos Buttler (Lancashire, wkt), Steven Finn (Middlesex), Mark Footitt (Derbyshire), Adam Lyth (Yorkshire), Liam Plunkett (Yorkshire), Joe Root (Yorkshire), Ben Stokes (Durham), Mark Wood (Durham).
