Wesley Sneijder opened the scoring in the 28th minute with a fine volley over goalkeeper Jurgen Macho after combining well with Theo Janssen to get through the Austrian defence.
Forward Klaas-Jan Huntelaar doubled the lead early in the second half with his 10th goal in his last six matches when he got the ball in at the near post after Macho misjudged a cross from left-back Erik Pieters.
"The way we approached and played this match said a lot about this team," Netherlands coach Bert van Marwijk told reporters.
"After a year with a World Cup and then a series of qualifiers it might be tough to focus on a friendly like this.
"But despite a sloppy start with some bad passes my team showed spirit and if you understand that you also have to win matches like this you are on course."
