Where "Branch Stacking" Comes From
"Branch stacking" describes signing up large numbers of members — sometimes without their full knowledge or genuine interest — to a local branch of a political party, specifically to sway the outcome of internal votes like candidate preselections. The term emerged in Australian political language from the 1960s onward, though the practice it describes is considerably older, and has been a recurring flashpoint in Australian party politics for as long as local branches have had real power over candidate selection.
Both major parties have been implicated in branch stacking scandals at various points, though it has been most publicly associated with Victorian Labor. A 2002 report by former Labor leaders Bob Hawke and Neville Wran described the practice as having a "cancerous effect" on democratic traditions. The practice sits in a legal grey area — signing people up to party membership without their informed consent can be a civil matter, but the underlying factional behaviour itself is rarely illegal.

How Aussies Actually Use It
"Branch stacking" is mostly heard in political and media coverage, describing internal party scandals rather than everyday conversation.
It's almost always used critically, implying an attempt to manipulate the democratic process within a party rather than a genuine grassroots recruitment drive.
