they are the company I have always used for VIP service in the old airport.

These days I do not need to use anyone, as I fly Garuda Executive Class from Sydney.

Garuda offers a service on these flights where you pay for your VOA at checkin, and then an Imigrasi officer comes thru the aircraft after the meal service, stamps you into Indonesia, and you get a laminated card like a boarding pass which says , cleared Immigration.

You just walk thru the crew line, hand it in, without stopping and go direct to baggage claim.

Worth flying Garuda if you are in the Sydney area just for this service
