For Australians, the 1st through to 32nd Battalions are entitled to trios.  Of these the 29th, 30th, 31st and 32nd Battalions did not have service at Gallipoli and not all received the Star, despite being in the area of entitlement.  This is also true in reverse, with some receiving the Star when they were not entitled.
Medals:
