Hi there,
Thank you for your question and photos regarding your situation.
Yes. You'll be a suitable candidate for consideration of a combined breast implant lift with a reduction approach. 
As a result of weight loss, your breasts appear to be quite deflated and droopy in addition to your moderate degree of breast asymmetry. The redundant saggy breast tissues will need to be removed for equalising the native breast volume between the two sides before appropriate pockets (either in front or behind your pectoralis muscle) to be created for allowing the implants to fill the deflated breast volume. This is followed by the appropriate tightening of the overlying breast envelope and lifting/reshaping of your nipple areolar complex to restore the balance & harmony of your breast shape & form. Depending on your situation and the type & level of cover from private health insurance, you may qualify for a partial rebate for the breast reduction component of the surgery provided there is evidence that it is performed for medical reasons. Your breast implant component however will be purely cosmetic with nil cover as the implants are used to optimise the aesthetic shape of the final outcome of your breast enhancement surgery.
I highly recommend you to seek an in person consultation with a specialist plastic surgeon for a proper clinical assessment to find out the most suitable options for you surgically, logistically and financially.
Hope that helps.
Best wishes

Hi and Thanks for posting your question and photos.
You have ptosis in both breasts and breast asymmetry. In considering the steps required to achieve your desired outcome, you must consider the following principles: 1. equalising the breasts, and 2. augmenting them. Some surgeons will do this as a two stage procedure; that is, equalising them first by reducing/lifting the right and lifting the left, followed by augmenting both at a second stage. Some surgeons will consider doing both at the same time. 
Some part of the operating (for breast asymmetry) will be partly covered by private health insurance/medicare depending on your level of cover, whilst the augmentation portion will be considered purely cosmetic. 
I hope this information is of help.
All the very best.
Warm regards,
Dr Ray Goh
