Some more data from https://ropengov.github.io/r/2016/06/10/FOI/:
Finland paid in total 131.1 million EUR subscription and other fees on scientific publishing in 2010-2015. The overall breakup of the costs is available as a separate table. The average annual costs for in Finland were 22 MEUR in 2010-2015; this is one third of the annual subscription costs in Austria (70 MEUR; Bauer et al., 2015), and two thirds of the annual expenditure (31 MEUR) in New Zealand. Data for the top-10 publishers in the UK 2010-2014 is available in Lawson, Meghreblian & Brook, 2015 (Table 1). During this period the UK paid altogether 4319 MEUR (rough estimate based on the exchange rate June 12, 2016) for the top-10 publishers. Finland paid 61 MEUR for the same top-10 publishers in the same period, which is roughly 17% of the UK expenditure per capita (unexpectedly low?). The costs in the other countries seem unexpectedly high compared to Finland.
