This arrived yesterday, sent via the more expensive USPS Priority Mail Express on 30 September. I think it is a cost issue rather than it being a problem at this end - one of our local papers reported a USPS rep as saying "Our ability to find available transportation capacity to Australia is driven by external forces which we do not control" - which I take as code for 'we can't find transport at a price that doesn't lose us money'. There was a temporary suspension of Australia Post (our USPS equivalent) receiving parcels while they cleared a back log, but that is no longer the case, and all the usual transport companies like DHL, Fedex, Toll etc. are still delivering as normal
