Test squad members Michael Neser, Mitchell Swepson, Mitch Marsh and Josh Inglis will link up with their respective BBL teams on Sunday.
Neser and Swepson will be rushed back into Brisbane Heat's XI for Sunday night's MCG clash with the Melbourne Stars.
Neser will be playing his first BBL match of the summer, while Swepson has already squeezed in two games.
Marsh and Inglis, both added to an extended Test squad after Travis Head's COVID-19 diagnosis prompted fears of an outbreak, will rejoin the Perth Scorchers on Sunday.
The quartet will travel via charter flight from Hobart to Melbourne.
Marcus Harris and Jhye Richardson will remain on drinks duty in Hobart throughout the remainder of the Ashes series finale.
BBL squads will be based in Melbourne throughout coming weeks as Cricket Australia tries to finish the season amid rising COVID-19 cases.
