Cubillo, who is an Aboriginal elder and has two university degrees, has lodged a complaint with the Commissioner of Liquor and Gambling Paul White, who has since launched an investigation.
On the day of her winning visit, Cubillo said she only had $7 with her. She played several machines before getting to the “Fort Knox” machine. She noticed the $1 credit and played in order to clear it.
“That is when all the lights and noises started on the machine and the jackpot came up,” said Cubillo.
The investigation has raised a legal question regarding the ownership of abandoned credits on slot machines.
