SELECT T2.driverid ,  T3.forename FROM races AS T1 JOIN results AS T2 ON T1.raceid = T2.raceid JOIN drivers AS T3 ON T2.driverid  =  T3.driverid WHERE T1.name = "Australian Grand Prix" INTERSECT SELECT T2.driverid ,  T3.forename FROM races AS T1 JOIN results AS T2 ON T1.raceid = T2.raceid JOIN drivers AS T3 ON T2.driverid  =  T3.driverid WHERE T1.name = "Chinese Grand Prix"
