What are you needing, type, rego, history? Second image (JHG) is a type of aircraft that always made my life difficult working in the tower at Bankstown, a PA60 or Ted Smith Aerostar. Popular with bank runs, they are a high performing twin (now there is a jet powered version) with high accident rates. I note this one has a very similar colour scheme to PWV, perhaps started life with the same operator.
Third picture shows the forward section of a Piaggio 166, I suspect it's the former VH- GOB

First picture is a twin bonanza, I suspect it's the former VH-SKY
