[citation needed] In 1982, Schubert was a member of the 1982 Kangaroo tour, the team being the first to go through Great Britain and France undefeated, earning themselves the nickname "The Invincibles".
Although not out of school at the time, Schubert instantly became a regular first grader on the wing – in the process relegating the previous season's leading try scorer Bill Mullins to reserve grade.
During the 1976 NSWRFL season, Schubert played at fullback as a wing for Eastern Suburbs in their unofficial 1976 World Club Challenge match against British champions St. Helens in Sydney.
After leaving Easts, Schubert signed with Western Suburbs for 1981 and played in the club's reserve grade grand final win.
He performances on tour saw him not re-signed by Easts and signed with the big-spending Manly club for 1983, playing a significant part in a rather successful season.
In recent years Schubert has been back in the headlines in his new role as auditor for the National Rugby League's salary cap and a number of unsavoury comments concerning breaches of the regulations.
On 22 April 2010, it was brought to his attention that the Melbourne Storm had been cheating the salary cap system for over five years, thus making headlines not only in New South Wales and Queensland but also the rest of the country and even overseas.
