I'd suggest using "minimum wage" instead of "minimum salary."

Examples:

[#2944666] What's the minimum wage in Australia? (CK) *audio*
[#1040499] Tom's been working for minimum wage. (CK) *audio*
[#2943037] It's hard to get by on minimum wage. (CK)
[#2943032] Tom and Mary were discussing the pros and cons of raising the minimum wage. (CK)
[#2943029] Everyone working for us earns more than the minimum wage. (CK)
[#2943023] Tom thinks raising the minimum wage would be a bad idea. (CK)
[#2943016] I heard that even a lot of college graduates have to work for minimum wage. (CK)
[#2943008] Would you work for minimum wage? (CK)
[#2943006] Do you think that the minimum wage should be raised? (CK)

[#2942992] Do you have any idea what the minimum wage in Australia is? (CK)

[#1542369] There's no minimum wage here. (Spamster)
[#1534782] What's the minimum wage in your country? (CK)
[#1336113] They're barely paid minimum wage. (Scott)
[#828804] The minimum wage in Okinawa is 642 yen per hour. (Scott)

I'd suggest the same change for all of these.
(I really wonder how many of the same pattern we need, but there are no guidelines about this. There are probably more interesting ways to introduce various county names into the corpus.)
