Swepson was named in a 14-player squad to play one T20I in England before departing for Zimbabwe.
This will be Swepson's first short-form international tour having been part of Australia's Test squad that traveled to India and Bangladesh in 2017.
The 24-year-old has played 21 games for the Heat, taking 21 wickets with an economy rate of 7.36.
Heat star batsman Chris Lynn was not considered for the squad with Australian cricket medical staff taking a conservative approach after his latest in shoulder injury sustained in February.
Lynn will meet with CA medical staff on his return from the Indian Premier League where he is playing with the Kolkata Knight Riders.
