Thanks N52.

Have now found that he was SSM instructor with Army for 7 years before going overseas.  Tomorrow I willlook for his actual enlistment.

thanks for the spur along the way.

Found this bit of info.

Am I correct in thinking   AASC  stands ofr Australian Army Staff College - just guessing.

No, I think he was in the Australian Army Service Corps (it didn't get its 'Royal' prefix until 1948). It was equivalent to the British Army's ASC.
In any case, a lieutenant would have been too junior to attend staff college - that's normally for majors and above.

[Nanna52]

Yes, Australian Army Service Corps.

Some abbreviations for Australian services are found here.

Thanks Andy and N52.   

 Sounds much better.  I think that was what I meant to write, but forgot between thinking and typing.   It happens too often these days!   

He was made up to Leiutenant as he was about to depart overseas.

I am learning!!
