In both England and Australia, once a woman became married her property was no longer her own and had to relinquish it to her husband.
In England, the married women's property act was enabled.

"The Act altered the common law doctrine of coverture to include the wifes right to own, buy and sell her separate property.[7] Wives' legal identities were also restored, as the courts were forced to recognize a husband and a wife as two separate legal entities, in the same manner as if the wife was a feme sole. Married womens legal rights included the right to sue and be sued. Any damages a wife might pay would be her own responsibility, instead of that of her husband. Married women were then also liable for their own debts, and any outside trade they owned was subject to bankruptcy laws. Further, married women were able to hold stock in their own names."
In australia 1883 The Married Women's Property Act of 1883 was enacted.

The Married Womens Property Act enabled married women to hold property of their own, sue and be sued, enter into contracts, be subject to bankruptcy laws, be liable for the debts contracted before their marriage, and for the maintenance of their children. Victoria passed legislation in 1884, New South Wales in 1879, and the remaining states passed similar legislation between 1890-97.
So, based on the above, the key difference that I can discern is that in Britain they were allowed to own stock in their own names, but not in australia?
