Tennis Australia was tipped off about the match-fixing allegations more than a month before the tournament started, with the ATP warning players of the bombshell that was about to be dropped. 
Fairfax Media has been told the ATP informed all players at a compulsory meeting at a Melbourne CBD hotel on Saturday. It is understood Tennis Australia also spoke to the management teams of several Australian players leading in to the tournament, to familiarise them with what was subsequently released by BBC and Buzzfeed on Monday.
It is understood several players have been approached in the past month by several media organisations in regards to suspicious betting and match-fixing in the sport.
It is understood Tennis Australia was aware of the players the BBC and Buzzfeed believed had allegedly been involved in matches with suspicious betting fluctuations.
The BBC/Buzzfeed did not release the players' names, referring to them by code.
On Thursday, another website, Show Legend, claimed to have decoded the Buzzfeed algorithm, which it alleged was the focus of the Buzzfeed report, and released a list on social media of names, including Lleyton Hewitt.
While the third party report strongly refuted any suggestion Hewitt was involved in any dubious activity, the ATP and Tennis Australia are hellbent on ensuring the Australian legend's reputation is not tarnished by the whole episode.
It is understood ATP and Tennis Australia solicitors are ready to launch a legal attack on any organisation that implies the two-time grand slam champion is involved or connected to match-fixing.
Fairfax Media contacted Hewitt's agent David Drysdale, who backed his client's stand in the press conference following his exit from the Australian Open on Thursday night.
"It is absolutely ludicrous that anyone would think Lleyton Hewitt would be involved in anything like this," Mr Drysdale said.
"Everyone in this country knows his character and there's no questioning his integrity."
Using an algorithm from information provided in the Buzzfeed report, decoders identified 15 players and a series of matches that raised flags because of betting irregularities.
Fifteen of Hewitt matches were flagged, including at least one in the Davis Cup, outraging tennis purists and a country that widely recognises the 34-year-old as one of the most competitive athletes Australia has produced.
While Hewitt's farewell was somewhat overshadowed by the speculation, the veteran did not shy away from the drama, describing it as "absurd" that his name had been thrown into the controversy.
"I think it's a joke," Hewitt said.
