VB flying to Bali, 737-900ERs have very good range (on paper). Range is shown on Boeing sites, as about 3200 miles.
These aircraft would be very good for Transcons, and range would be good for SYD/MEL to DPS as well.
Over in America, Continental are using these planes with 20 Business Class seats, 153 Economy Seats, so these aircraft could let DJ offer quite a good Y+ service on big time business markets.
