I believe JQ17 MEL-HKT is a Boeing 787 flight, which is a bonus. In economy you will get seat back IFE although I think you have to pay for some/all of it. USB ports/power points only in business class.
Food, drinks, amenity kits etc. not included, but available for purchase (unless you're in business). You do get 20kg of baggage though.
I had a friend look at booking this flight using Qantas points, until we realised that for $200 more (than the tax co-payment which is close to $200 itself) she could just buy the fare directly from Jetstar and save the 24,000 points. Something to consider.
