A Canberra man who stole more than $1 million from Indigenous Business Australia, using the money to fund a luxury lifestyle, has been sentenced to five years in jail.

Nicholas Ian Schofield, 46, was a financial officer at the Commonwealth-funded authority, and stole the money in amounts ranging from $50,000 to more than $300,000.

He pleaded guilty to eight charges relating to the thefts.

Schofield used the money to fund several overseas trips, a wedding, clothes and an Aston Martin sports car.

In a police interview, Schofield noted it was easy for him to steal the money.

Justice John Burns said the crime required planning and sophistication, and that Schofield had repeatedly breached people's trust.

He labelled the offences "serious", and sentenced Schofield to five years in jail.

Schofield will be eligible for parole in 2018.
