First, Australia does not have any direct citizenship pathways for general migrants (exceptions are for cases such as children born overseas to an Australian parent). You would need to obtain permanent residence in Australia first, then accumulate considerable residence periods in Australia to qualify for
citizenship. Generally, this is at least three years of residence in Australia during a four-year period (there are specific rules around this such as no more than three months away during the last 12 months). For business and investment pathways for Australia, there is no specific country advantage other than English threshold requirements to reduce visa fees can be met through demonstrating certain citizenships such as the U.S. Aside from this, the requirements and quotas are the same across all countries. However given tighter regulatory controls in the U.S. versus some other countries, you may require less documentation to support the legal acquisition or earning of funds. The investment pathways for Australia are either AU$2.5M or AU$5M - AU$2.5M, requires two years of stay in Australia during the investment period (3-5 years), while AU$5M requires only 40 days for each year you've held the
visa (3-5 years) (The 40 days x years = accumulated total, you are not required to spend the time in each year). These are initially temporary visas, after maintaining the investment and meeting the requirements such as residence periods, you can qualify for permanent residence, and then later with residence in Australia meet the citizenship requirements. The advantages of Australian citizenship include the unrestricted property purchasing (foreigners are limited to new developments only,
not the larger re-sale property market), the right to residence in New Zealand, free education in schools and subsidised education at university, public healthcare (medicare), social security benefits and many others.
