The NDP had no electoral success after 1987, and the 1990 election was the last at which the party ran a serious campaign. After several years of inactivity, the party was revived for the 1998 election. It attracted little support in its second manifestation, and was eventually formally disbanded in December 2009, when it voluntarily relinquished its registration with the Australian Electoral Commission (AEC). In the meantime, many of its initial members had either returned to the Labor Party or become involved with the Australian Greens.
