The battle saw the Australian Army thwart further movement by the Viet Cong and delayed its attack on Saigon.
Tocumwal RSL president Alf Grayson, who is a Vietnam War veteran and fought in the battle, said the battle’s importance was often lost on Australians.
“The battle was a really important battle, but one that is often overlooked,” Mr Grayson said.
“Because they made a movie about Long Tan, everyone knows about that, but no-one remembers the Battle of Coral -Balmoral.
“It was just as important, if not even more important.”
More than 75 people attended the dinner. A dozen veterans were there, including Gloria Welch, one of the few known surviving World War II women’s air force members.
Ms Welch, who served in the Women’s Auxiliary Australian Air Force (WAAAF), is 99 years old and was also commemorated at the dinner.
“I had the opportunity to invite Ms Gloria Welch to the dinner after I heard about her and what she did during World War II,” Mr Grayson said.
“At the dinner, we spoke about the importance of WAAAF and how they have contributed to the Australian war effort, and we spoke about how Gloria was involved in this.”
The Tocumwal WAAAF Walk is the only memorial in Australia that commemorates its service to Australia’s war effort.
Two commemorative dinners are planned each year by the Tocumwal RSL, with its Remembrance Day dinner set to be held in November.
Mr Grayson said the RSL planned to hold this commemorative dinner again next year.
