Here's Peter Ryan.
PETER RYAN: During his time as Telstra's chief executive, much was made of Sol Trujillo's Hispanic background, even though he's a first generation American.
He was constantly referred to as an "amigo" or one of the "three amigos" along with his two American confidantes - the head of public policy Phil Burgess and the chief operations officer Greg Winn.
The characterisations clearly hurt and speaking to a BBC interviewer in San Diego, Mr Trujillo said they were unacceptable, and that elements of Australia were racist and backward.
SOL TRUJILLO: You know, many Australians have come up to me and they've apologised because they're embarrassed by that kind of behaviour.
STEVE EVANS: Because I noticed reading papers the papers there, that when you were referred to they would always point out that you were, had a Hispanic background or whatever.
In other words in Britain and in America it would have been neither here nor there; in Australia it was invariably pointed out.
And the Prime Minister, when asked what his parting words to you would be said "adios".
Was that racism?
SOL TRUJILLO: I think by definition there were even columnists who wrote stories that said it was.
But you know, my point is that, you know, that does exist and it's got to change because the world is full of a lot of people and most economies have to take advantage - including Australia - of a diverse set of people.
And if there's a belief that only a certain people are acceptable versus others, that is a sad state.
PETER RYAN: It's not the first time Sol Trujillo has raised the race card.
Speaking to AM in February last year, Mr Trujillo said he was troubled about the constant Hispanic references.
SOL TRUJILLO: Well, I think they are unique. I don't think there would be references made like that in most other countries and I have worked around the world.
PETER RYAN: But did you think those comments went against what might be your personal standards or what the standards might be in the United States.
SOL TRUJILLO: Well, they clearly are not the same standards as in the US or Europe - you know I have lived in France or the UK - but they are what they are here and you know, my view is people should be judged on who they are, not where they come from.
PETER RYAN: Few of Sol Trujillo's friends or foes have bought into the issue.
The ACCC chairman Graeme Samuel and his predecessor Alan Fels were both unusually silent.
But a long time critic, the telecommunications analyst Paul Budde, believes Sol Trujillo was happy to call himself an amigo.
PAUL BUDDE: Very early in his reign, he actually made that comment and he, you know in quite a funny way he was talking about it. I honestly believe it never was taken in any negative racial context. You know it was just a funny story at the time.
PETER RYAN: But three amigos was a consistent message in the media and also in business and in politics and remember the Prime Minister said "adios". Do you think we are all being just a bit too sensitive about this?
PAUL BUDDE: We don't have to be oversensitive in a situation like that. True, Sol Trujillo has been an extremely controversial person and obviously that whole situation with the "amigos" had been continued but you know, it had more to do with the close knit sort of American management relationship that was established by Sol Trujillo you know, that basically operated outside the management of the existing, call it native, Australian management .
PETER RYAN: The World Today sought a range of legal opinions on Mr Trujillo's racist claims but none were forthcoming.
And the Human Right Commission which covers all areas of discrimination declined to comment on Mr Trujillo's complaints.
