Hi Meg,
It can be a big step to take getting breast reconstruction after so long. Congratulations on taking that step.
Women most definitely can have breast reconstruction in the public system, you might find some specific barriers in your local region like waiting lists or capability and equipment (like for micro surgery options).
Many many women seek this surgery, like you, as a delayed procedure and can have wonderfully satisfying results. You can connect with these women and view their stories in the Breast Reconstruction Online Group. Request membership and we will help connect you.
Your next step might be to get a referral to a plastic surgeon, your GP should be able to assist you. You could also ask for recommendations in the private group or do a bit of a ring around or ask your local breast care nurse.
Lots to think about, but yes definitely you can get reconstruction in the public system, doesn't matter how long after BC it is.
cheers Louie
