Procurement, engineering and fitting out of the aircraft is expected to cost US$2 million.  It is expected that based on the expected number of missions and hours flying, the aircraft will be viable for 5 years.  It is then anticipated that the engines and aircraft will be able to be sold for US$2 million.  These funds will then be used to purchase a replacement aircraft.

People who volunteer their time and expertise must become financial members of OpAir.  The membership fee prior to procuring an aircraft is $25.00.

Once an aircraft has been procured, membership will be $500.00 to participate on missions.  The reason for this is that the aircraft must be a "private" aircraft and so be funded by individuals.  If the aircraft is not a "private" aircraft, the Civil Aviation Safety Authority (CASA) of Australia will require extensive documentation for the granting an Air Operator's Certificate (AOC).  The $500.00 membership fee will be refunded, upon request 12 months after the member withdraws from OpAir.
