I'd also advocate for using CloudFreeNight as a higher precision Australian option (

Using the ACCESS-C data from BOM, this is more accurate than the data from the GFS model (which is probably what most are using), and you may be able to find a town on the list that is closer to you. The accuracy of the ACCESS-C model is down to a 1.5km area, so can be quite good.
I have found it to be extremely accurate in it's predictions.
