The use of trusts and other tax-minimisation vehicles used mostly by higher-income earners will be targeted by a Labor government after Bill Shorten promised to end the nation's "two-class tax system".
As experts rejected the Opposition leader's assertion that inequality in Australia was on the rise, Mr Shorten said Labor would target the "whole different set of rules for people with the financial wherewithal to mine the plethora of choices for aggressively minimising their tax".
These included vehicles such a trusts, vast property portfolios, complex deductions and "parking their money in offshore havens".
Mr Shorten said there were two classes of Australian taxpayer, the vast bulk being of pay-as-you-earn workers, who he called "economy class", and "then there's business class, beyond the curtain where a different tax menu is served".
