Morgan (18), who is on the Perth Scorchers’ supplementary player list, made the final 15 ahead of four other West Australians selected for the initial 30-man squad.
The South African-born left-hander looks destined for the professional ranks, having become a regular performer on the international youth cricketing scene.
He starred with a century as Australia’s captain against Zimbabwe during the team’s tour of India in September and October last year.
Following the tour, the big-hitting wicket keeper-batsman was called up as 12th man when WA drew with Victoria in its opening Sheffield Shield match at the MCG earlier this season.
As a 16-year-old, he top-scored with 47 in his WACA first grade debut for Joondalup in an innings where the Centurions made just 144 on a tricky Fremantle wicket.
WACA talent manager Brett Jones said Morgan had worked hard in the past 12 months to harness his raw talent.
‘The World Cup represents a great opportunity for him to be exposed to a higher standard and further develop his game,’ he said.
The Australian squad heads to Sri Lanka at the end of the month to play three warm-up games, before taking on Namibia in its opening World Cup clash in Abu Dhabi on February 15.
