The Holden Astra is a small car formerly marketed by Holden. The first couple of generations of Astra were made only for Australia, and was a derivative of the locally produced Nissan Pulsar. With the Button car plan coming into effect, it was replaced by the Holden Nova, a rebadged Toyota Corolla.

The Button car plan, also known as the Button plan, was the informal name given to the Motor Industry Development Plan, a Hawke government initiative intended to rationalise the Australian motor vehicle industry and transition it to lower levels of protection. It took its name from Senator John Button, the then federal Minister for Commerce, Trade and Industry.
