Four helo services up that way, according to my intel - Sky Safari, Cape York, Aust Helicopters, + Gt Barrier Reef - Sky Safari have R44 & R22 (4, 2 incl pilot), Cape York have R44, Bell 206 & AS350 (4, 5, 6-7 incl pilot), Aust Heli 206, BK117, Bell 412 (5, 9-11 max, up to 10), & GBR Heli's have R44, 206, 206L +AS350 - probably at a guess booked Cape York with 2 x AS350 @ 6-7 ea max people = 12 - 14 bums on seats.
