International rugby rules ban him from being on the field, but ACT Brumbies mentor Stephen Larkham will become the first Super Rugby head coach to double as a waterboy.

Super Rugby's governing body SANZAR has cleared Larkham to become the most high profile waterboy.

IRB protocols states head coaches are not allowed to run in the water but because Laurie Fisher is the Brumbies’ director of rugby, SANZAR has cleared Larkham to be on the field while Fisher is in the coach's box.

Larkham will be the only head coach in any Australian sport to be an on-field coach.

Meanwhile, the Brumbies will host the Reds in their opening match of this year's Super Rugby season on the 22nd of this month.
