Holloway's stage career spanned over three decades until it was cut short when she moved to Hollywood with her actor husband Robert Greig.

A theatre critic commented on her performance saying Holloway "played with natural intelligence and utter absence of self-consciousness, quite remarkable for a little girl of 7.

[5] Niblo and Holloway had met while preparing for George M. Cohan's Get-Rich-Quick Wallingford which had its Australian premiere at the Criterion Theatre in Sydney, in August 1912 and later became a movie.

As early as 1920, Greig was already keen to take their acting talents overseas and he and Holloway left for England in 1920 to attend to Tivoli Theatre business, returning to Melbourne via America.
