The head of the world players' representative body has warned that the International Cricket Council's new powers to seize phones could jeopardise players' privacy and says he would be stunned if any Australian or England players were caught up in spot-fixing.

The ICC's anti-corruption unit is in the early stages of a wide-ranging investigation that will stretch into five countries including Australia in an effort to discover if sensational allegations made by two alleged Indian fixers in British tabloid The Sun have any substance.

While the most shocking of the claims of Sobers Joban and Priyank Saxena - about a supposed spot-fixing plot in the third Ashes Test - was quickly played down by anti-corruption unit chief Alex Marshall last week, Australia will be a key part of the probe.

In undercover footage captured by The Sun, Joban and Saxena boasted that they could arrange fixes on three or four Big Bash League games and that a former Australian player and an Australian administrator had been involved in passing on information on BBL matches. They also alleged that an Australian fixer they called The Silent Man had current and former internationals working for him.
