In Australia, the entire city of Canberra is leased from the federal government, with most blocks being on 99 year leases.

The original idea was a Georgism-inspired approach to capturing land value increases through rent to help fund the city's development, but nowadays it functions effectively like freehold, as most lessees do not have to pay anything other than nominal rent, and you can renew your lease effectively automatically every 99 years, with the added interesting complexity that the government uses additional lease clauses as a form of planning controls.
