The 100 per cent owner of Australian telco giant Optus, the Singapore Government-controlled Singtel, states it has “zero tolerance” for “bribery and corruption in any form”.

Former NSW Premier Gladys Berejiklian has been found to have engaged in “serious corrupt conduct” after a multi-year probe by the NSW Independent Commission Against Corruption.

Nine months after Telco giant Optus — overseen by former NSW Premier Gladys Berejiklian — announced a “review” into the nation’s biggest data breach it’s refusing to release the findings.

The embattled Tax Practioners Board will be forced to reveal whether its former chair — who was in charge for the entire PwC tax leaks investigation —recused himself from the probe, including from board meetings.

The long-time chair of the Tax Practitioners Board — who departed immediately before explosive senate hearings into the PwC tax scandal two weeks ago — spent almost a decade working for the same accountancy as disgraced tax practitioner Peter Collins.

An alleged mastermind of PwC’s tax leaks scheme was just weeks ago providing nationwide training seminars to the Australian Taxation Office – and was personally praised by the Taxation Ombudsman.
