I own a 16-room student accommodation, and have had hundreds of tenants over the years, mostly overseas students. Overall, I find them pretty good tenants - most of them have families who've worked really hard to send them to Australia to study, and they are grateful for the opportunity and do little but study and maybe the part-time work they're allowed to do. Generally not party animals.
The primary "danger zone" is the couple of months immediately before they're due to depart the country. They don't care about getting listed on TICA, because they never plan to rent in Australia again, and once they've left Australia, you've got no hope of ever recovering anything. A not-insignificant portion of them have figured out the rules and will stop paying rent about 4 weeks prior to leaving, so that they eat up their bond and once you can do anything about it, they're gone.
I get my PM to be incredibly vigilant in the last month. We do an inspection about 3 weeks prior to departure, so that if there are any obvious necessary repairs due to tenant damage, we can highlight that to them at the time and ask them to fix it. If they stop paying rent, the day after their regular rent payment would normally be due, the PM gets in touch and reminds them that it's in breach of their lease conditions to chew up their last month from the bond.
Whilst there's little we can do if they don't choose to repair / continue paying rent, we find that most of them will if you just ask nicely. They've been lead to believe by others that it's just accepted practice to stop paying rent, and in particular, they think that getting their bond back is one less thing to worry about when leaving the country. When we point out that it's a violation of the lease, and could affect their future prospects of renting if they return to Australia, and how quickly they can get their bond back legitimately (and tell what we'll do to facilitate that), most are willing to fall into line. But we've built up goodwill by being good PM/landlord while they're there.
