The smaller letters spell out the names of places in Australia from where soldiers came, and some of the letters in these are highlighted to make bigger letters that spell the names of places where the Australian soldiers fought - in this example "MEGIDDO"

"The last major battle of the campaign at Megiddo is an excellent example of how the Australians not only affected the statistics of the campaign, but the operational employment of mounted forces as well. It was the Australian commander of the mounted forces, Chauvel, that launched his corps into the operational depth of the enemy's defences. It was the Desert Mounted Corps that was able to exploit the destruction of the Turkish armies in a major operation which culminated in the capture of Damascus and the pursuit of the Turkish forces to the Taurus Mountains.
During an engagement in the Megiddo battle at the village of Semakh, the Australians demonstrated their tactical flexibility by quickly reverting to their mounted infantry role. This happened even though they had been armed with the sword and legitimately reclassified as "cavalry". They were not inhibited from adapting to the situation and fighting with rifle and bayonet when it was required. There exist no examples of the British cavalry doing the same, although their doctrine provided for such actions." (from www.lighthorse.org.au/military/austwar.htm )
