Although they used to have several remote bases, Chartair have closed down their Tennant Creek, Warburton and most recently, Borroloola bases. Probably can't compete with the other operators like KA, Territory Air Services, etc on price.
Only remote base now is Hooker Creek - which is most likely operated on behalf of Lajamanu Air, which is a community owned enterprise, but definitely a Chartair pilot there now operating the C210.
Still have their Katherine base, as well as Alice Springs and Darwin.
CP wouldn't be described by many as "friendly", but does seem to make the effort to speak to pilots if they can catch him in the afternoon - spends time in both Alice Springs and Darwin. They have given heaps of newbies a start straight out of flying school and seem focused on training their pilots to fly the way they want. All pilots full time, and if not flying are expected to work hard at washing aircraft, etc.
