Used Scuba Diving Equipment – Why is Operation Wallacea So Expensive?

Used Scuba Diving Equipment – They claim to be a non-profit charitable organisation, but a 6 week engagement costs £2400 excl. long haul flights, internal flights, overnight hotel stays, meals before and after transfers to expedition sites, and visas (£60). The accommodation is basic (usually sharing with at least one other person) with no proper shower or bath facilities, no free use of scuba diving equipment, and food consists of tuna and rice. Indonesian staff are evidently underpaid. So just where is all the money going to?
