Marginal rate and tax on the whole salary
Your marginal rate is the rate on the next dollar. It is not the share of your salary that goes in tax. On $100,000 the marginal rate is 30%, while the effective rate, including Medicare, is about 22.52%. The full resident bands are on the tax brackets page.

Estimates for an Australian resident who claims the tax-free threshold. Employer super is 12% on top of ordinary earnings unless you mark the salary as including super. Full-time hours are 38 a week across 52 weeks, with no overtime. HELP is included only when that option is on. Weekly, fortnightly and monthly nets follow ATO withholding, so they can differ from the annual net split evenly. This is not personal tax advice.
