The banker son of Australian Prime Minister Malcolm Turnbull is the latest of a list of individuals to open up on alleged dubious deals linked to troubled Malaysian sovereign wealth fund 1MDB.

According to The Australian, Alex Turnbull claimed he was sidelined from his executive position at Goldman Sachs in Singapore four years ago after blowing the whistle on billions of dollars of allegedly dodgy deals done with 1MDB.

The report quoted Turnbull as saying that he had raised concerns with his colleagues about the US$6 billion of bonds raised for 1MDB in 2012 and 2013 and the lack of clarity in offer documents about the use of the funds.

“When the 1MDB deal was done with Goldman I sent an email to some of my colleagues saying, ‘What the f..k is going on with this? The pricing is nuts, what is the use of funds?” he was quoted as saying by The Australian.

"And I got a talking-to by compliance (division of Goldman Sachs)," said Turnbull who was reportedly not involved in organising the bonds that had reaped the global investment bank almost US$590 million in fees and commissions.

He also said he was "B-tracked" as a result and later resigned from Goldman Sachs in 2014 to start his own Singapore-based hedge fund, Keshik Capital.

"Whistleblowing is a shit business," he was quoted as saying.

Mongolian model

In raising his concerns at Goldman Sachs, The Australian also quoted Turnbull as having made reference to the 2006 murder of Mongolian national Altantuya Shaariibuu, who was killed in a patch of jungle near Shah Alam.

"How many Mongolian models did we have to bury in the jungle for this pricing?" he said.

The report further stated it was believed a similar remark to his colleagues had earned Turnbull a telling-off from Goldman Sachs’ compliance division.

The Australian in its report also highlighted that Turnbull’s claims came as Prime Minister Najib Abdul Razak is preparing to face the 14th general election and could undermine efforts by Canberra to shore up relations with Malaysia, regarded as a key ally in its battle against terrorism.

Further, it stated that Turnbull's claims could lead to an uncomfortable encounter between Najib and the Australian prime minister at a special Association of Southeast Asian Nations (Asean) summit in Sydney next weekend.

Najib has denied any wrongdoings linked to 1MDB.

The US Department of Justice (DOJ) in its civil asset forfeiture suit had alleged there were three principal phases of money-laundering through 1MDB, one of which involved US$1.367 billion raised through two separate bond offerings arranged and underwritten by Goldman Sachs International in 2012.

Last November, it was also reported that Singaporean prosecutors and police are looking at Goldman Sachs Group's relationship with 1MDB through meetings with its current and former employees.

Malaysiakini is unable to independently verify the claims made in The Australian report.
