Kay,
Thanks for the question -  though it is a hard one to answer directly.
It is difficult to give a direct answer as there are a lot of variables and options in what you are asking, The duration of the procedure, the type and extent of the tummy tuck, and if the breast lift will need an implant to restore volume, as well as if there is private insurance that may cover some of the costs, are all questions that need to be considered when the cost is estimated. 

As everyone is going to be individual, the cost will vary from person to person and surgeon to surgeon, and  even offering a range is difficult as the difference between two people asking for the same procedure can be quite large.
The best option will be to be seen in a consultation, and from there a surgcial plan can be made, and cost estimate given
 I hope that makes sense and is of some help

Hi Kay
Pricing for any procedure, especially multiple procedures, is very complex. In my office, we work out how many hours I think it will take, then the team needs to look at if you will qualify for any item numbers, how much you will get back from your health fund, and if your health fund will cover some or all of the hospital costs.
Your best bet is to choose your Specialist Plastic Surgeon and get a proper quote - anything that you get from a forum without an assessment is likely to be inaccurate.
Good Luck
