I'm assuming you are in Australia?
Here we have protections on certain bank accounts that the federal government assures. FDIC insured you can generally have up to 500k and not worry about it getting stolen or lost if the bank goes under, as the federal government will cover it. (Private insurance generally covers amounts above that.)
Does Australia have something similar to protect you?
This says they are a "non-bank" -- what exactly does that mean down there?
www.rams.com.au/about-rams/why-choose-rams/Many legalese terms are different, so I hesitate to offer advice on it. We also have something called a Better Business Bureau to look up how many customer complaints a company has and how they were resolved. Do you have an equivalent to that?
Finally, have you tried googling the company?
That about page makes it seem like they've been around at least a few years, and have been noted by some different financial publications, so they seem to be at least somewhat legitimate.
