This comic is undated. Dating is an estimate from www.ausreprints.com. The cover lists this as issue 9. However there is no known issue 8 and two number 9s. This is the earlier of the two issues and should probably have been issue 8.
The end of this story reports "To be continued! In the pages of All-Star Squadron #15 "Master of Worlds and Time!" That story was not printed in Australia and there was no Australian All-Star Squadron series -- although the US series was consistently imported and distributed in Australia.
