Fact-check
This post is strongest when it focuses on the 30 per cent floor itself. The Budget does apply a 30 per cent minimum tax floor to post-2027 capital gains, including share and ETF gains, and that floor can bear more heavily on lower- and middle-rate investors than a pure progressive-rate approach would. The broader claim that the reform hurts young people more than it helps them is still an all-things-considered judgement that depends on housing, income, and portfolio assumptions. But the narrower design criticism of the floor as flattening outcomes across brackets is materially grounded in the announced tax mechanics.
Prefills a post-2027 ETF-style savings case so the 30 per cent floor critique can be pressure-tested against tax-rate and inflation assumptions.

By mandating a 30% floor, the government is effectively imposing a flat tax that ignores the progressive nature of the Australian tax system.

The Budget text describes a broad capital-gains redesign rather than a property-only rule, so ordinary share gains are within scope.

“the 30% floor is a regressive measure that unfairly targets low-to-middle income Australians trying to build wealth through shares and ETFs.”
That narrower design point is materially right. A flat minimum floor binds hardest where a taxpayer's marginal rate would otherwise be lower than 30 per cent, which is why the floor can compress away part of the ordinary progressivity of the tax system for some lower- and middle-rate investors.

Budget 2026-27 Tax reform page Capital gains tax · p.1 The reform introduces a minimum 30 per cent tax on gains from 1 July 2027. ATO: Tax rates – Australian resident Resident tax rates 2025–26 · p.1 Resident marginal tax rates below 30 per cent show why a flat 30 per cent floor binds differently across taxpayers.“By mandating a 30% floor, the government is effectively imposing a flat tax that ignores the progressive nature of the Australian tax system.”
This is a fair characterisation of the floor's design effect when kept narrowly framed. The ordinary income-tax system remains progressive overall, but the 30 per cent floor does impose a common minimum rate on affected gains regardless of whether the taxpayer's normal marginal rate would otherwise be lower.

It raises the cost of the one wealth building option still available to me while getting locked out of the property market.”
This broader claim goes beyond the floor's design mechanics and depends on how much young households actually rely on shares and ETFs, whether housing-policy benefits offset that hit, and what other Budget measures matter to them.

“shares investing is caught in the blast radius.”
This is a framing judgement about legislative intent rather than a discrete factual claim.
