While former cricketers lined up to hail the success of "a ripper of a bloke" in landing such a big job, Australia coach Darren Lehmann gave a reminder that immediate success for Bayliss could mean failure for his country.
"Trevor has been a great servant of the game in Australia and has had great success with New South Wales in both the long and short format," he said from Antigua, where the test side are preparing for a series against West Indies.
"A trademark of Trevor's teams are that they are well prepared and this just serves as another reminder to us that this Ashes will be a tough contest."
English cricket fans will be happy if Bayliss has as much impact on their team, humiliated 5-0 in the last Ashes series in 2013-14, as Lehmann had on Australia after taking over in the wake of the sacking of Mickey Arthur in 2013.
If Bayliss does manage to galvanise England in time for the start of the Ashes in Cardiff on July 8, it is safe to say it will not be through extended data analysis or complicated tactical or psychological interventions.
Bayliss will certainly bring inside knowledge of the Australia side with Michael Clarke, Steve Smith, David Warner, Mitchell Starc and Josh Hazlewood among those to have played under him at New South Wales.
