An employee at one of the big four accounting firms has been sacked after he and another man allegedly accessed Prime Minister Anthony Albanese’s personal banking account.

The men, aged 21 and 25, faced court on Tuesday over the breach which Australian Federal Police alleged occurred when the EY graduate was on secondment at the Commonwealth Bank.

Paul Issa, 21, was charged with accessing restricted data without authorisation, as well as distributing personal data.

Phillip Issa, 25, was charged with facilitating unauthorised access to restricted data.

The two Sydney men were charged on May 6 and granted bail to appear before Downing Centre Local Court on Tuesday, an AFP spokesperson said.

Both men had their bail continued until their next court appearance on August 25.

According to his register of interests, Albanese has a savings account at CBA, as well as a mortgage for a property on the Central Coast that is jointly owned with his wife.

Treasurer Jim Chalmers said any breaches of that kind were “incredibly concerning”.

“Not just in relation to the PM’s details but any Australians’ details,” he said.

A CBA spokesperson said it was not appropriate to comment on individual contractor matters.

A spokesperson for EY declined to comment, but confirmed the former employee was no longer working at the firm.

The big professional services firms have come under increased scrutiny of late, after scandal engulfed rivals KPMG and PwC for leaking confidential information about client audits and tax policy, respectively.
