Can inheritance money affect FTA or FTB or baby bonus/maternity leave payments?

My DH may have some inheritance money coming to him, not sure of when it will come through or how much it will be (could be $10,000 or could be up to 50,000). Just wondering if i have to consider it when working out whether to go for baby bonus or the other one.

Also, does anyone know if it affect tax thresholds etc ? (i know that is not a centrelink qu)
