'Lost' super is a big issue and not an easy one to solve. The ATO have had a 'lost super' web service for years, but part of problem is the database is only updated with 'lost' funds i.e. where there is returned correspondence etc.
Also, older employer funds often didn't get the TFN, so there's another disconnect.
For a number of years now a small fund with employer contributions could not be reduced below $1,000 by fees (although insurance premiums can), so peace I don't know what happened to you but I think there's more tho the story of your $25k......
My concern about any automatic rollover is the potential for losing insurance cover and the loss of control.
Bottom line is only the individuals can really be responsible for making sure they keep track or track down, older super funds. It's as simple as that.
