190,000 is not enough
It is not possible to make a recommendation on Australia's permanent migration policy with a single number.
It doesn't matter what amount we nominate - what matters is that the migration intake is accompanied by an appropriate set of well-designed and supportive policies that enable migrants to best achieve their potential. This involves providing adequate infrastructure and services as our population grows, as well as ensuring fair and inclusive economic opportunities for new migrants, in relation to education, employment, access to business opportunities and other essential services such as safe and affordable housing, and ensuring new migrants have a voice and representation in decision-making.
Australia's current demographic circumstances also strongly warrant investment in migration. Australia's birth rate (1.58 babies per woman as at 2020) is well below replacement-rate levels, meaning migration is the key mechanism for replenishing the country's workforce as older generations age.

I have indicated 190,000 as a minimum, on the basis that higher population growth has the potential to foster greater economic prosperity and wellbeing for all.
Migration has brought wide-ranging benefits to our country, including through innovation as well as cultural benefits.

When considering an upper limit on migration caps, keep in mind that 30% of all Australians were born overseas. For 20% of Australians, one or both of our parents were born overseas. Most of us wouldn't be here in Australia if it weren't for migration.

Clearly any population growth policy also needs to be accompanied by well-informed resource sustainability policies, so that higher population growth and economic development does not come at a cost to our natural resources, environment and ecosystem.
These dual goals are achievable if we take a holistic approach to policy design and recognise the mix of policies that are required, aiming for "inclusive" and "sustainable" economic prosperity, not just economic growth at any cost.
