More players revealed match-fixing approaches on Tuesday as the Australian Open Grand Slam tournament came under close scrutiny following claims that corruption in tennis was widespread.

Australia's Thanasi Kokkinakis said he had been targeted through social media, while a British former Davis Cup player said he was once offered an envelope stuffed with cash to throw a match.

According to Australian media, police were also checking for suspicious results at the Australian Open.
