Depends on what you mean
by 'the migration crisis'
If you're talking about people coming here by dangerous boat crossings instead of having safe routes, I'd say setting up safe routes would be a good step.
For those already here, I'd say putting in an effective system to process the massive backlog of claims, so legitimate claimants could get on with their lives, work, pay taxes, contribute to society, and so on .
The 'crisis' of our government weaponising the plight of these relatively few souls, who seek asylum here, as a distraction from their own mismanagement??
I don't really know, plenty of people seem ready to lap up that story of 'our own' homegrown homeless being homeless because of 'immigrants' don't they?
I'm not sure how you cure wilful ignorance, and a basic lack of understanding, awareness, and humanity.
I really wish I knew, the answer to that one 🤔
