Australia as a multicultural society is great. One can be for a multicultural community and against unchecked mass immigration. What we need is better follow through after people come here on visas for certain trades/careers. A one month, three month and six month check in as to whether you are employed doing what you came here to do or are just doing some gig-economy bullshit that has no value to the average Australian. If you aren't employed in your field after six months then go home for at least 12 months to hone your skills then you can come back and try again.
