Turning to the future, Alexander said there would be more expansion in the big data space.

"We've got other areas within Treasury where people are still doing manual Excel work so we want to make better use of business analytics," he said.

In addition, the Treasury is also in talks with other organisations in the federal government who use the same kind of source data.

"We want to build a data warehouse that other federal government organisations can all share," he said.
