Just on the face of the info you have provided, If you have been married for a long time (say 20+ years) and your home has been your family home and the kids have vacated and left you free from providing them any legal support, I think if you saw a solicitor that you would find that you are entitled to 50% of her Super as she is entitled to 50% of the House.
If you have been in a married or defacto relationship for any shorter period (say 10 years) then sometimes you may be entitled to split the assets on the basis of what you bought into the relationship. So in this case if you have been together for only 10 years and she has worked 25 of the 10 then she may be able to argue that the prior 15 years of super is hers.
The same would apply to your super and possibly in this case as you paid off the house with yours she may owe you a proportion of this amount.
It is a must to seek legal advice. And best if you can attend as a couple.
