Great Ocean Walk - advice please

My husband and I are flying down from Mackay, Qld to Melbourne in April 2024 and we are looking for the best and most cost effective way to transfer from Melbourne airport to Apollo Bay.
We are also trying to work out how to get gas canisters for our Jetboil stove, as we are unable to bring them with us, as we are flying. Has anyone else flown down and been able to get some gas canisters delivered to their accommodation in Apollo Bay.
Any information or advice will be very much appreciated.
