Nicholas Schofield is accused of using his position as a senior employee at Indigenous Business Australia to syphon funds to finance a lavish lifestyle of overseas travel and luxury cars.

Schofield allegedly bought prestige cars - including an Aston Martin Vantage - as well as property in Adelaide, and paid off credit card debt with the money, court papers said.

The IBA reported the alleged fraud in January but the police waited more than six months to lay criminal charges.

Last month, an ACT Supreme Court pre-trial mention of civil proceedings, launched by the IBA to recover $1.343 million, heard police had charged Schofield.

ACT Policing declined to confirm the criminal proceedings due to "operational sensitivities" when questioned by Fairfax Media.

It is understood Mr Schofield is scheduled to appear before the court next month.

A mention before Justice Richard Refshauge this week heard the lawsuit had stalled as the defendant's previous legal representative had withdrawn.

The IBA has made a liquidated demand against Schofield in an attempt to recover money.

Court documents from the civil case allege Schofield made large transfers of IBA funds into his private bank account on eight occasions between July 2013 and August 2014.

The largest is said to have been $371,500 around May 14, 2013.

Earlier this year, the authorities froze Mr Schofield's bank accounts and assets, ordered him to surrender his passport, and seized the Aston Martin and a Mini Cooper.

Court documents said Schofield had full access to IBA finances through his job and the alleged theft involved creating payments for existing clients.

He would then allegedly substitute his account details before the funds were transferred.

Schofield, court documents said, admitted to spending more than $400,000 of IBA money to buy a unit in the Adelaide CBD, the luxury cars, furniture, and a mountain bike.

He said a further $340,000 cash in his account was IBA funds and he had used the rest to pay off credit card debt he owed for travel abroad.
