Taking out computer-generated investment advice could make sense for more than 1 million Australians, says robo-adviser Six Park, after the Hayne royal commission further damaged the reputation of the financial planning sector and raised its costs.

Traditional face-to-face financial advice businesses face tighter curbs on fees and tougher disciplinary rules as a result of the Hayne royal commission, and some experts have predicted this could give to a boost to the nascent robo-advice sector.

Six Park, a "robo-adviser" founded by former Future Fund board member Brian Watson, says its conservative estimate is that 1.1 million people, some of whom are currently advised by a human, could be suited to robo-advice.

It comes as rival Stockspot says the royal commission could already be having some impact, after it posted the strongest four months of inflows between January and April.
