Two solutions spring to mind: Both have a precedence as a guide.

Initiate a commission of enquiry into African Youth crime and violence, and as a conclusion, pay these youths from taxpayers funds, a three figure amount, for pain and suffering, caused by their negative experiences in their new country, Australia.

Precedence: Payments made from taxpayer funding, for pain and suffering caused by the forced occupation in Dondale Youth Detention centre, NT. to incarcerated youths.

More realistically, legislate a mandatory brain scan of all offending youths, with the aim of isolating those with psychopathic tendencies for correctional treatments. One treatment could be, placed against a double brick wall and shot.
Another could be a one way aeroplane voyage over the Pacific, and ejected from the cargo hold, at three thousand feet.

Precedence: The slaughter in Australia, of thousands of unborn children through abortion practices.

Young Australians are like 'old people, what have you done to our country'

Not as completely stupid as it sounds?

Now on that theme? Why not have a voluntary postal survey to see if there's any appetite to return/repatriate these young hoodlums and thugs to their countries of ethnic origin?

Even if that meant setting them adrift off an african/arab coastline in the dead of night, with enough supplies to allow them to survive for a (character building) paddle your own canoe, fortnight?

Well, not too different from the then acceptable to them, personally chosen, manner of their arrival?

When enough examples have been repatriated, willing or not? Some of these folk and their AWOL parents may start taking personal responsibility and owning their own behavior?

Moreover, these excuse making ethnic misfits and their benefit supported unemployed parents, ought be obliged to resettle in regional and rural australia!

To earn a living picking fruit etc, as opposed to their current entirely unproductive and aggressive, ghettoized (taxpayer supported) behavior?

Alternatively, accept voluntary repatriation! As opposed to making it all our fault!

Don't like it here, our customs, culture or laws pal?

Well, how about we pass that hat around for a few, one way airfares? And get them on their way!

We could even supply some volunteer helpers to help them pack.

Turnbull and Dutton are responding to the reality of inordinate African youth violence in Melbourne.

Meanwhile the Victorian Labor Government is in ideological and electoral denial that a specific ethnicity (and within that a specific age group) can be more prone to violent crime.

The gangs and antifa are very similar in their hate for decency and luv of violence. Pollies like Turnbull and Shorten care nothing about the average person putting up with this c rap. People who live in highly indigenous populated areas have suffered for decades while being labelled racist for calling crime for what it is. Tribal thinking is definitely inferior to places influence by Christianity. Its time previous immigration ministers were charged with treason ratther than live on massive pensions in leafy suburbs.

So you think 'Christianity' isn't a form of tribal thinking?
