Business groups unite in fierce opposition to Chalmers' budget tax legislation

Business groups of all shapes and sizes have united in their mission, setting their hair on fire in response to the central pillar of Jim Chalmers' federal budget.

The chorus of detractors hasn't faded since budget night, but has risen to a full throated roar just as the treasurer introduced the tax legislation to federal parliament on Thursday.

Sure, the whole point of any lobby is that it reflects the self-interest of those represented.
