Greek prime minister Alexis Tsipras has urged ministers to get on with reforms demanded by creditors so the country can exit its bailout programme in 10 months.
Mr Tsipras told his cabinet in televised remarks that the country was on course to outperform budget targets set by creditors for the second year running.
He said Greece's surplus, before debt servicing costs are taken into account, will be higher than the 1.75% of annual GDP demanded.
Bailout inspectors are currently in Athens but negotiations on the next batch of loans are not expected to start until November.
Conditions for future disbursements include the continued reorganisation of public sector personnel and further deregulation of the state-dominated energy utility.
The previous bailout review was delayed by more than six months.
