The proposition, a financial transaction tax on high-speed share traders, capital gains tax on “mansions over $2 million” and an inheritance tax on estates worth more than $5 million.

“When politicians speak in Canberra’s Parliament, it’s not the average Australian we are hearing from anymore,” Senator Lambie said at a business breakfast in Burnie on Wednesday.

“It’s the voice of the people who’ve avoided paying their fair share of tax for years, the foreign interests, or those who have cosy interests with the government.”
