Maureen In addition to my other reply. It appears that you don't know where George and Elizabeth were married. The cheapest and best way would be to obtain one of the Qld. children's birth certificates. Up to 1889, they are available at the Qld. State Archives at Runcorn. [ about $18] Include in your request that the marriage information be included. Their death certificates should also have their parents names. The Qld. State Archives are on the net and you can download a request form.
