Seems like in Australia we're in a pretty good position with "superannuation" https://en.wikipedia.org/wiki/Superannuation_in_Australia being compulsory since 1992 and is typically managed by completely unrelated parties to your employer.
The payments are generally made directly by your employer into the fund of your own choosing.
The biggest thing is once you've had this contributed to YOUR account, it is YOURS (drawable from age 65) and doesn't matter what happens to the fortunes of your employer(s) in the future.
