If you don't have access to a public oncologist--they are rare in regional areas--you will have to pay for the cost of seeing a private one. Out of pocket for that around here is about $140 per visit, but the actual chemo treatment doesn't cost anything.
You will have to pay for any discharge meds, which can be pricey. A hint here, get any prescriptions filled at a discount pharmacy; hospital pharmacies charge the full PBS rates which can be considerably more expensive than you will pay elsewhere.
