Federal opposition leader Angus Taylor has vowed to deliver one of the biggest immigration cuts in Australian history and called Labor "socialist in all but name". This was reported by Qazaqyia.kz citing The Guardian.

In a wide-ranging address to the NSW Liberal party state council in Sydney on Saturday, Taylor admitted the previous coalition government had its shortcomings, but said Labor was "utterly failing the nation".

"For the past four years, we've had a government in Canberra which is socialist in all but name," Taylor said.

Taylor said it was "divisive" for Labor politicians to "stand in front of three different flags instead of our one national flag", referring to press conferences where leaders would deliver speeches with the Aboriginal Torres Strait Islander flags alongside the national flag behind them.

After Labor unveiled its new immigration plan, which includes transforming a former quarantine facility into a new detention centre, and preventing international students from bringing their family members to Australia, Taylor offered to go further.

"I will deliver one of the biggest cuts to immigration in Australian history," he said.

The opposition leader also promised to protect Australia's national flag and Australia Day, and change laws regarding gender.

"We will not allow the ideologues and activists to deny the truth … Under a Coalition government I lead, we will end this lunacy," Taylor said.

The Coalition will be hoping to win back voters from One Nation at the NSW state election in March.

Meanwhile, tributes were paid to Victorian Greens MP Tim Read.
