Prime Minister Malcolm Turnbull and his Vietnamese counterpart have agreed to settle the details of future commemorations at Long Tan in order to avoid future misunderstandings.
Mr Turnbull met with Vietnamese Prime Minister Nguyen Xuan Phuc on his final day of talks at Vientiane, Laos on Thursday morning.
During the bilateral meeting, it is understood Mr Turnbull raised the issue of hundreds of Australians being unable commemorate the 50th anniversary at the site of the battle of Long Tan after being blocked from the location last month.
The leaders agreed officials should settle the details of future visits to the site in order to avoid any misunderstandings in the future.
Last month Foreign Minister Julie Bishop said the Australian government was only formally notified about the ban to the site the day before despite months of preparations.
Following talks on the issue, hundreds of visitors were able to visit the site, however hundreds missed out.
