As always, it's a school student who asks the best questions at the Reserve Bank governor's testimony to the House of Representative parliamentary committee on economics.

In addition to facing a grilling from federal politicians at Glenn Stevens' twice a year appearances, it has become practice to let two high school students ask questions as well.

Mitchell from Faith Lutheran College in Plainland, Queensland wanted to know what provisions have been put in place since the global financial crisis to strengthen the economy.

Mr Stevens said that he has tried to keep the economy growing by keeping interest rates low and state and federal governments have been reducing debt, so they are ready to spend if the economy takes another downturn.

"There were shortcomings in financial regulation, so there's been quite a big push of regulating the banks and some other sectors of the financial sector so that we don't face a crisis of that severity again," Mr Stevens said in Brisbane.

"So that's a very big work program that is ongoing."

Mr Steven also mentioned part of Australia's leadership of the G20 this year is to push governments to stimulate their economies by building more infrastructure.
