Our Zafira 2.0DTI has a flanged plug with a rubber o-ring seal instead of a copper washer,to undo it you need a torx socket,size tx45 I think.Your astra is probably the same.Most of the local motor factors sell torx tools singly or in small sets. If you have the plastic "ecotec" engine cover,you need a smaller torx to get this off for oil filter access.(tx30 I think)If you look around the engine,you will see bolt heads with flutes instead of flats,these require female torx sockets "E" numbers.All designed to discourage home maintenance!!!!! *For easier oil filter access,you may need to remove the intercooler hose.Also,observe the torque setting for the plastic filter top.Although a large socket (36mm)required,torque is only 25Nm.
