In our part of rural Australia ute (utility vehicle) is largely reserved for the classic Australian Ute (eg: 1974 HQ Holden Ute: https://www.youtube.com/watch?v=cztnXaND-Xo) which is a non US car footprint that'd be at home in Europe, cut down from a family sedan to be a single front bench seat in a two door cab, with everything behind as a tray.

Other parts of Australia do vary

As such things get bigger, get more doors, and veer towards a US size they get called crew cabs, trucks, pickup's, etc.

  Traditionally, the term referred to vehicles built on passenger car chassis and with the cargo tray integrated with the passenger body (coupé utility vehicles).
  However, present-day usage of the term "ute" in Australian English and New Zealand English has expanded to include any vehicle with an open cargo area at the rear, which would be called a pickup truck in other countries. 

doesn't speak for all Australians and veers toward city usage.
