If you ring the hospital they will be able to send you pricing.

I just looked up my file from when I had DD and the charge for me was $4920 but my DD was prem and was in the SCN for 4 weeks and the charge for her was $16305! I am thankful that we had private health insurance as all we paid was an excess of $200 each for myself and my DD. I had a spinal block for a MROP which was a further $383.85 charge covered by PHI plus there was pathology claimable from Medicare

There were no theatre fees involved so you need to be aware that if it turns out that they can't go ahead with the VBAC then you would be up for fees for a caesar as well.

I hope this helps.
