The world No.142 lashed the media and boasted about his wealth just minutes after his loss to little-known Italian Lorenzo Sonego on Sunday.

"I just count money, that's all I do. I count my millions," he told reporters.

"You go do what I did (on court). You go make $13, $14 million. Good luck, guys."

Retired world No. 1 Andy Roddick said the 25-year-old's behaviour was "self inflicted" and disappointed tennis fans blasted him as being undeserving and an embarrassment to Australia.

Tomic, who reached a top ranking of 17 in January 2016, is now expected to slump further in the ATP rankings. His career earnings are listed as $6.6 million (not including earnings from sponsorship deals).

"I just count money, that's all I do. I count my millions. You go do what I did. You go make 13 million. Good luck guys".

As vision of Tomic's spray spread, his name began trending on Twitter on Sunday afternoon.

Roddick said he had no sympathy for Tomic. "Maybe stop for a second and think of the millions you've left on the table," he wrote. When a follower criticised Roddick, the American tennis player said Tomic's troubles were "self-inflicted".

"Young Bernard Tomic once boasted he would have the 'heart of Hewitt, the groundstrokes of Federer, the mind of Sampras'," wrote sports reporter Anthony Sharwood. "He achieved none of that. But he did manage to develop the personality of a complete dickhead."

Wrote Frenzal Rhomb guitarist Lindsay McDougall: "I reckon Bernard Tomic should pay someone else to count his millions so he can practise playing tennis".

But it was a tweet asking people if they were proud Tomic is an Australian that garnered more than 100 responses - the majority of them negative.???

"What he just said was a disgrace," came one reply, while another commenter praised rising Sydney tennis star Alex De Minaur.

The 18-year-old is currently ranked 167 and was commended on Saturday by Andy Murray for his great attitude.

But many came to the defence of Tomic who they claimed was tired of his job just like anyone else.

"He's going through stuff and got some anger issues," wrote one. "We all go through it. Just because he's a public figure, doesn't make him any less human. Tired of his job, we've all been there."

But Tomic is renowned for his controversial outbursts and off-court behaviour.

In an extraordinary press conference after crashing out of Wimbledon last year, the Queenslander said he had little desire to win.

"I feel holding a trophy or, you know, doing well, it doesn't satisfy me anymore," he said.

"It's not there. I couldn't care less if I make a fourth-round US Open or I lose first round. To me, everything is the same.

"I'm going to play another 10 years, and I know after my career I won't have to work again."

In an interview on Channel Seven's Sunday Night program, Tomic also claimed he never really loved tennis and had built his career on "50 per cent" effort.

"Wouldn't anyone want to take a job in a professional sport in one of the biggest sports in the world and only give 50, 60 per cent and earn millions of dollars?" he said last July.

"I think everybody would take that."

On Sunday, some social media users appealed for critics to cut Tomic some slack, speculating he was obviously lost and unhappy in his career.

But it seems there is little love lost, with most armchair commentators pleased Tomic did not qualify for the grand slam.

A cutting headline on Monday's Courier Mail sports page reads: "Flaunt your cash all you want but money can't buy you respect, champ."

Rumours Tomic is about to star on Channel Ten's reality series I'm a Celebrity... Get Me Out of Here! persist but are unsubstantiated.
