Tennis Australia (TA) has accused Bernard Tomic of deliberately trying to sabotage Australia's tennis culture in the wake of his public criticism of Lleyton Hewitt.

And Tomic will remain an outcast in the Davis Cup and wider Australian tennis community, according to TA chief executive Craig Tiley.

A week after expressing hope Tomic and Australia's cup captain Hewitt could mend their fractured relationship, Tiley savaged Tomic.

"Lleyton is right to say Bernard will not be considered for Davis Cup," Tiley said on Saturday in a statement.

"Bernard does not meet the standards of behaviour and commitment to himself, the team or the sport.

"Now, he is deliberately trying to damage that culture, and not for the first time."

Hewitt said during the recent Australian Open that Tomic would not be considered for Davis Cup selection during his tenure as captain.

His comments came after Tomic, after his first-round loss in Melbourne, bitterly criticised Hewitt, saying no-one liked the Australian captain and he favoured certain players.

Hewitt in turn claimed Tomic had threatened his family.

Tomic's father John also said Hewitt left his son traumatised in 2010 by pressuring him into revealing who in TA was "against" him.

But Tiley on Saturday dismissed those claims.

"We are not aware of any formal complaint lodged by either John or Bernard," Tiley said.

"Both Bernard and John have enjoyed a lot of support since in many areas of their lives, including a long and sustained period of personal commitment and wholehearted effort from Lleyton Hewitt as Davis Cup captain.

"Our organisation remains deeply disappointed with the ongoing disrespect from Bernard and his father.

"We have given more than a decade of support. Ultimately, we have to draw a line when the behaviour does not warrant the support."

Hewitt snubbed Tomic for selection in Australia's Davis Cup tie against Bosnia and Herzegovina, which continued on Saturday in Adelaide.

Last Tuesday in the lead-up to the tie, Hewitt refused to discuss his ongoing feud with Tomic.

"I'm not going to waste my time on that now," Hewitt said at the time.
