>>33354602i also '''owe''' ~$90k.
the amount of worry correlates directly with your situation.
i'm 31 living at home on roughly ~85k (construction estimator) and at 4% threshold i pay about 3.5k a year.
that's nothing for me, but if you rent, have dependents, want a mortgage etc it can be a worry.
just keep in mind to NEVER EVER make additional contributions. i'm personally convinced that every election cycle they will keep cutting HECS to some degree to secure votes.
