Not always the case.
Property settlement is all about the couple's contributions, mutual assets and liabilities incurred during the marriage.
Even if wife never worked and husband was the sole breadwinner during the marriage, her contribution is still 50% as long as the marriage lasted over 10 years.
Also, the party who has more time in custody of their children gets some adjustment to the split percentage. That's why most women try to keep their kids in their custody as much as possible, not necessarily they love them more than husband. Child support payment is calculated based on parents income and % time.
Another factor the court considers is the current income and future prospective. Whoever has lower current income and likely to be the same in the future will get some adjustment to their % split (usually 5-10%).
Each party's super will also be splited, not just husband's. Future pension is not included in the property settlement.
