If it was piece based, instead of showing the suitcase with 30Kg written inside, it would show the suitcase with x 1 next to it and say 1 piece underneath ( or higher numbers if applicable )

Also, if you look at https://www.qantas.com/au/en/travel-...d-baggage.html and check your itinerary against this page, you will see the allowances

What is your ticketed itinerary ( including stopovers ) ; I assume that it is not a standalone Sydney-Melbourne ticket since that should be 1 piece max 23kg in economy
