The contest continues over the future of Australia's tax system following last week's Federal Budget. The Coalition has flagged its own bold policies on tax and housing, while the Treasurer is working to sell a trio of changes affecting negative gearing, capital gains and trusts. Two new opinion polls suggest his federal budget has been poorly received by voters - but Jim Chalmers has declared the long-term gains from controversial housing tax changes are worth the short-term political pain.

The Federal Government says it's investing $1.2 billion in First Nations communities and Closing the Gap over five years as part of Tuesday's budget. Headline measures include new funding for remote jobs, community controlled health infrastructure, and programs to combat gendered violence. Despite these investments, some community leaders have told NITV they feel the budget left First Nations people behind.

Cuts to the National Disability Insurance Scheme are the largest source of savings in the federal budget, leaving many in the disability community angry and anxious about what's to come. The details of which participants will lose their supports, and whether state governments will fill those gaps, are still being worked out.

What do the changes mean for renters and potential buyers in the housing market?

There are big changes ahead for the NDIS with some budget cuts and tightened eligibility. Health Minister Mark Butler says the government aims to remove around 160,000 participants by the end of the decade. Children with autism are the largest cohort of NDIS participants, with many set to be moved into the government's new thriving kids program and he says future eligibility will be based on a different set of criteria. He says work is also being done on cultural safety before Indigenous participants are transitioned off the NDIS under the new reform measures. Mr Butler's been talking the SBS Chief Political Correspondent Anna Henderson.
