Exactly what fees are you trying to pay? For an immigrant visa (CR-1), that would be the NVC processing fee and the Affidavit of Support fee....which are not applicable for K-1 cases.
For a K-1? What checklist? There is nothing to submit to NVC for a K-1. For a K-1, NVC simply assigns a DOS case number, then forwards the case to the consulate.

Then, you will not qualify for a K-1 visa. K-1s are for couples who wish to marry inside the US. After marriage, you would qualify to apply for a CR-1 spousal immigrant visa.
You can interview in Australia.
You could easily be looking at another month before your case is "ready". No need to worry yet. Waiting is the hard part of immigration. It is not uncommon for some couples to be separated for a year and longer. Nothing happens fast in the world of US immigration.
