Victoria Liberals Win Nepean By-election, One Nation Influence Grows

The Liberal Party won the Nepean by-election, but saw a drop in first preferences. One Nation's vote share increased, showing its growing influence in Victoria.

Victoria's Liberal Party has secured a win in the Nepean by-election, reportedly fending off a challenge from One Nation. The outcome, however, signals a complex political landscape ahead of the state's November general election. Premier Jacinta Allan has previously stated that Victoria “can’t afford” a Liberal-One Nation government, pointing to the Liberal party's reliance on preference deals with One Nation as a key concern.

The Nepean by-election results suggest a complicated road ahead for the Liberal Party towards November's statewide poll, despite claiming victory.

The by-election in Nepean, where the Labor party did not field a candidate, saw Liberal candidate Anthony Marsh declared the winner. This win is being framed as a first electoral test for the new Liberal leader, Jess Wilson. Yet, reports indicate Wilson faced a significant drop in first preferences, with One Nation and a Teal independent siphoning votes, raising questions about the party's broader appeal.

One Nation's performance in Nepean, while not a victory, has underscored its growing presence and potential to influence Victorian politics. This challenge comes as the party experiences a rising popularity in national opinion polls, though tempered recently.

Premier Jacinta Allan's government has recently undergone a cabinet reshuffle following mass resignations of three ministers. Allan has been promoting new MPs to fill these positions, a move that comes as internal party concerns mount over her leadership and the potential for a "disastrous election loss" in November.

Meanwhile, on the federal stage, the Labor government is not ruling out extending the fuel excise cut. This indicates ongoing consideration of measures to alleviate cost-of-living pressures.

Broader Political Currents

The situation in Victoria reflects wider populist movements in Australia. The Liberal party's strategic challenge involves balancing appeals to both its traditional base and more moderate, urban electorates, particularly in light of the rise of independents and parties like One Nation. An attempt to reclaim voters by moving further right risks alienating key constituencies needed to form government.
