> As luck would have it, global healthcare plans seem reasonably priced. My partner and I got covered under Aetna's MHP Exclusive plan (their most comprehensive package) for under $300 a month total (not $300 per person).
As an Australian, this figure seems ridiculous, even if it were in $AUD! To give you an idea, I pay around $45 AUD/mo (but I've never had to use it because free healthcare).
I pay about 600 EUR a month and that only covers up to 3 months abroad (but abroad can be anywhere) — for longer trips I still do at least a “major medical” policy and I have MedEvac insurance, so my effective price for an ad-hoc global insurance is probably more like 700-800 per month.
Which on the one hand is horrendous, but on the other hand very competitive with serious global policies that cover everything everywhere for someone my age.
These are great for getting temporary coverage while you wait for a residence permit, but there are few use cases for them outside of that. In Germany, I actively try to steer people away from them.
