Travel packages from Sydney to QLD

Hi ladies I’m looking for travel packages for a family of 5.

Im wanting to book a cheapish holiday for my family and I with flights from Sydney to QLD with accomodation and the ticket packages for sea world ect..

My kids will be 6 years, 19 months and 7 months old at the time and I’m trying to find the best deals and prices for a whole package instead of individual prices. Preferably one I can book for January and pay off as we go 😊

Thanks in advance
