Tennis Australia relies on rumours, newspaper reports or individual reports to notify it if a coach is abusing children, a royal commission has been told.
Ann West who is the peak tennis body's business, compliance and risk manager on Tuesday told a commission hearing into child safety in sport there was no formal process in place requiring affiliate organisations to keep Tennis Australia informed of sexual misconduct by a coach.
"It is either through the rumour mill, the newspapers or someone comes to us with information," that a database is kept updated, Ms West said.
The commission is examining how the tennis bodies responded to complaints about high-performance tennis coach Noel Callaghan who allegedly sexually molested a number of young female players in the late 90s.
Callaghan was never convicted of these offences and later went on to be a selector for Tennis Australia.
Ms West said that when Callaghan came to Tennis Australia he was self-employed and had a certificate saying he was safe to work with children.
The commission heard that Callaghan resigned from Tennis NSW in 2000 to defend himself against a number of charges relating to sexual offences against young players.
It also heard that Tennis NSW never took action against him and, after legal advice, put the onus on one player, referred to as BXJ, to go to police.
As a result BXJ, who had a promising career ahead of her, abandoned tennis and became ill, her mother told the commission.
The Tennis NSW board would now consider an apology to her, its current CEO, Alistair MacDonald said on Monday.
