> We get 4 weeks of vacation, health insurance, 4 months parental leave, and other benefits
As any permanent full time employee in Australia working for any employer, you'd get a minimum of 2 weeks of public holidays (depends on state), 20 days of annual leave, 10 days of personal leave (carer's & sick leave), and 12 months parental leave. There's health insurance funded through the public system decoupled from employment.
Compared to US this probably seems relatively socialist, compared to europe things are relatively neoliberal.
Excluding retirement fund contribution, equivalent base salary would be around 155k AUD. That'd be subject to roughly 29% total income tax. There are no additional state level income taxes . So you'd end up with around 110k AUD cash. A single person who rents & shares a place can cover all baseline living expenses on a quarter of that.
