Sadly mate I don’t believe it would. Vic roads are some of the worst in Aus and yet the state has the 2nd most people and 2nd most millionaires/billionaires. Not to mention Aus also has a very high tax rate already for those making good money. Furthermore, most billionaires are not liquid net worth billionaires. The ultra wealthy hardly ever have millions in the bank. Their wealth is typically tied up in equity in a company and it’d tank the company stock if they sold everything. The wealthy will usually borrow against their collateral assets instead. That’s why “tax the rich” is an oversimplification of a more complex issue.
