Telephone country code +61 is Australia, and numbers beginning with +61 4 are mobiles. However, it is incorrect to refer to "country code +614"; the correct country code is just +61.
(The plus signmeans "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
