Hi Jeff,
Yes as a child of the deceased you are entitled to obtain a copy of the will or view it under the Succession Act (Qld) 1981
Section 33Z requires the person that has possession of the original or a copy of the will to allow a child to inspect the will or obtain a certified copy of it. (Where a certified copy is obtained, reasonable costs should be paid by the person obtaining the copy.) It doesn’t matter if the validity of the will has not been confirmed. Check out this blog post that gives more info:

I would contact the executor of the will or if you know another person holds the will, contact them and request to see the will.
In Australia there is no requirement to have a formal "reading of the will", so no to that question. And, no if the will has not been read yet, and no one knows what specific items have been formally gifted in the will then it is not adhering to the wishes of the deceased if you were to take things from the home until the executor says its okay to do so. The executor is responsible for distributing the estate in accordance with the will and owes a duty to beneficiaries to preserve the estate until it can be distributed to them. There can be serious consequences for failing to do so.
