Melbourne to Bali (1 stopover in Bandar Seri Begawan, Brunei) on Royal Brunei Airlines from $289. I've checked the dates, and sure enough I could find it for that price.
Royal Brunei Airlines is not a low-cost carrier, so baggage/entertainment and food/drinks are included on board. RB IS a "dry airline", so they don't serve alcohol onboard, but you can buy something in duty free and have it served on board.
Seems like its a STA Travel "exclusive"; as other booking engines are showing 500-600$ for the same fare.
