Stories of Yamada burying his treasure on the east coast of Australia (and in particular, Magnetic Island off Townsville) persist but it is highly unlikely that Yamada would have ventured into that area as there were no trade routes in this region and the only ships to venture to this region were the ones blown off course during the summer storms.
The lead character in the film is based on Yamada Nagamasa, a Japanese adventurer who later became a governor in the Ayutthaya Kingdom.
