Asked what the Coalition will be doing for renters this election, (you know, that pesky one-third of us), shadow housing minister Michael Sukkar said…cutting migration:

Well, the centrepiece of our budget in reply was for renters. The centrepiece was a major reduction in migrations to this country. We know whether it’s international students, whether it’s the permanent migration programme, whether it’s other visa classes, bringing more than a million people over the last two years, has driven rents up by nearly 20% at the heart of a reduction to the
big Australia policy that Labor’s trying to progress is ultimately a policy to support renters, because the only way you can help them is to reduce the demand on the rental market. And we’ve been we’ve been in the midst of a perfect labour storm on housing, fewer homes, particularly here in Victoria, fewer rentals available because of the huge taxes that Labor has imposed on
housing.

So we know there are fewer rentals in the market, and then more than a million people in two years who are fighting for a dwindling number of rentals.

So our policy, again, we’ve spoken about it on Sunday, we spoke about it in the budget in reply. Peter Dutton will speak about it between now and Election Day, we have to get our migration programme back to a sustainable level. If we do that, I think one of the biggest beneficiaries will be younger renters

Not sure if I need to tap the sign, but cutting migration is not going to suddenly make rentals affordable.
