The return of Smith and Warner was expected and it was always tight for Handscomb to find a place in the World Cup squad after their return.
The return of Steve Smith and Warner from their year-long bans for ball-tampering has left selectors in a quandary, with openers Aaron Finch and Usman Khawaja building a formidable partnership in recent one-day internationals.
"Both are world class players and it has been pleasing to see them produce some good form in the IPL", he said.
Warner has registered five 50-plus scores, including an unbeaten century, for Sunrisers Hyderabad in seven IPL matches this season while Smith, returning from an elbow surgery like his former deputy, has also looked in good touch for Rajasthan Royals.
Hohns said Hazlewood, who is included in Australia "A" one-day and four-days squads, remained a big part of Australia's Ashes plans.
Smith and Warner have also been added to Cricket Australia's 2019-20 contracted player list, which was released shortly after the World Cup squad announcement. Alex Carey has been named the sole wicketkeeper in the squad, which also contains all-rounders Marcus Stoinis and Glenn Maxwell. "And Alex Carey he is elite-fit and is as tough as they come".
Hazlewood, who is yet to recover completely from the back injury he sustained in January, has scalped 72 wickets in 44 ODI appearances.
'Having not played at the highest level for some time, we feel this will provide him with the best preparation to get some quality cricket under his belt, ' Hohns said.
Jhye Richardson, who dislocated his shoulder last month, makes the grade along with Nathan Coulter-Nile and Jason Behrendorff.
Australia will have matches against England and Sri Lanka before the kick start their title defence against Afghanistan in Bristol on June 1st.
Starc and Richardson have both been selected subject to fitness.
Meanwhile Langer has said he will "mix and match" the three opening options of Warner, Aaron Finch and Usman Khawaja in three warm-up games against New Zealand in Brisbane. The seamer hasn't played a one-dayer for Australia since November due to a back injury, but has still been one of the team's best bowlers for the past two years.
"Unfortunately, from the recent squad which toured India and the UAE, Peter Handscomb, Ashton Turner and Kane Richardson have made way for the above inclusions, but all three have been included in the Australia A squad for the tour of England".
