Meg Lees and The Dems saved us from a GST on everything...
The Democrats under Lees, strengthened the Environment Protection and Biodiversity Act, improved the Pharmaceutical Benefits Scheme, negotiated the GST tax reform and maintained the general oversight role of the Democrats in the Senate through a number of Senate inquiries. She brought the Dems back to the centre after the Kernot debacle and started "keeping the bastards honest" once again.
In 1999, Prime Minister John Howard (re)proposed a Goods and Services Tax.
It was opposed by the Labor Party, the Australian Greens and independent Senator Brian Harradine, which meant that it required Democrat support to pass. In an election fought on tax,
the Democrats publicly stated that they didn't like either; the Liberal (GST) tax package or the Labor package, but pledged to work with whichever party was elected to make their tax package better. They campaigned with the slogan "No GST on food". A
majority of the senators in the party room agreed to
pass the bill if some amendments were made, mostly to exclude fresh food and essential items such as basic medicines.
Stott Despoja was unhappy with the outcome, particularly the GST on books.

Both Stott Despoja and Queensland Senator Andrew Bartlett crossed the floor, to vote against the GST package.
Some Democrat members were unhappy with the GST deal, and began to agitate for a change in leadership. These were the LEFT of the party. Under the Democrat constitution, a petition of 100 members could trigger a leadership ballot of all the members.
On the initial ballot, Meg Lees was returned unchallenged. Subsequently the Democrats faced a decline the polls... The members again had a leadership ballot and this time, Stott Despoja announced her intention to challenge Lees for the leadership, and was successful, replacing her on 6 April 2001. The rot continued.
In mid-2002, Lees began vocally opposing Stott Despoja's leadership, claiming that it had moved the party too far to the left. This unfortunately culminated in Lees leaving the party to sit as an independent.
The party was put last by both major parties and has never recovered since. Many LW members jumped ship and joined the Greens.
