This template is only for use in lists - for other uses, {{Census 2006 AUS}} is preferred. The link template is used with a single parameter, "id", which is the alphanumeric key following "LOCATION CODE:" in the ABS statistics pages, or in brackets in the second-to-top line in the ABS spreadsheet. The most common reason for broken links is an incorrect ID.
Usage: {{Census 2006 AUS link|id=}}
